Capo Testa (Sardinia) - Underwater History

Lost Civilisations - The Myth of Atlantis


    Since before the 1500s, the myth of the lost city of Atlantis has fuelled the imagination of creative hipsters through the ages, including Philo Judaeus, Plato, Francis Bacon, Abraham Ortelius and importantly, the Scottish musician Donovan.

'Way down.....below the ocean....'

    And even more importantly, it inspired (Sir?) Julian Courtland-Smith to create one of the GREATEST boardgames of all time - 'Escape from Atlantis'.


Even if I don't win (which is never), it still feels like I'm just generally winning at life when I play Escape From Atlantis. Those beautifully coloured figurines, the danger and destruction from sea monsters, that tantalising tessellation of those hexagons, I could go on... 
(picture from nostalgianerd.com)

   However, in our real, non-game world (if there even is such a thing), there's a planet full of hidden histories and ancient relics immersed beneath the waves that can offer inspiration of what we think the Lost City of Atlantis would look like. For example, there is...  


Capo Testa


    In the North of the Italian island of Sardinia there is a peninsula named Capo Testa (in English this means the Cap of the Head) which used to be a Roman stronghold in terms of military strategy, but also for resources for its Capital City. Granite was threshed from the Capo Testa landscape and hauled to mainland Italy to build Rome itself. If you look closely at the sea-eroded scenery you can see signs of an ancient civilisation that must have worked incredibly hard!

Spacious, atmospheric property with excellent sea views...

Would you describe those stairs as whimsical, kooky or just plain deadly?

    Tiny, hidden clues of a time-worn community are dotted around Capo Testa. However, even more impressive are the often hilariously shaped rocks moulded both from bygone quarrying work and of course by the powerful erosion from the Mediterranean sea.

This rock looks like an elephant or a bird with a large beak. Other suggestions are welcome.

Get your sunscreen on, some tough beach/walking shoes, your best lenses (including for sunglasses as well as for cameras) and enjoy the views.

     Just be aware that, although it may seem like you are looking at the rocks...

...the rocks are actually looking at you.
(Like the Gnome King in Return to Oz - if you get that reference, you are officially a spirit sibling of mine...)

Capo Testa (Underwater) 


   Alright fellow humamphibians, let's dip our heads under the water and see what Capo Testa has hidden under its quarryl-some waves.

But not before observing Ol' Rocky Face here..

    I mean, the water in Sardinia always looks so inviting, it practically orders you to go for a swim!

Viewgasm

    Due to the erosion of the waves, it is difficult to interpret whether or not you are looking at aged stairways, statues or simply weather-beaten rocks.

Look at that centuries-old anger on this guy..

    You can see plenty of wonderful schools and shoals of fish near the surface of the water as you admire mysterious sub-aquatic structures....

Shoaling societies definitely still call this place a home

    Walls and bridges can often look impressive and/or imposing, but underwater they are cleansed by the beauty of the sea..

I've never really been too keen on walls (unless they're the underwater sort).

Would you say that this could be a bridge over and under sometimes troubled water?

    The underwater scenery can be so breath-taking, but don't actually forget to breathe. After all, beautiful landscapes are all around, especially in the form of the Capo Testa Lighthouse sitting atop its kingdom of majestic rocks and fantastic beaches. 

The completely automatic Capo Testa Lighthouse was built in 1845. Facts.

Sardinia Travel Advice


    In all honesty, it's best to get a rented car and travel to where your instincts are pulling you. In the city of Olbia, there are many low budget hotels. There are numerous fantastic places to go and the sea is beautiful everywhere you look, especially if you visit during the summery months (June to September). If you're into history and archaeology, there is a wealth of cultural treasure all around Sardinia. Sometimes you have to let your inner explorer come out from its hiding place and treat your psyche to wonders from lost ages.

Cave? Staircase? Sea? How about all three, those are your decisions...

    But, make sure you take time to relax and enjoy the warmth and the sea breezes with a pizza and granita combo. Keep your eyes peeled whilst Tyrrhenian Rock Lizards scuttle past:

This one seemed to like posing, but most of the time they just want your food..

    So pack plenty of sunscreen (factor 30-50 for Gingers like me), some insect repellent and a well-organised map of fantastic destinations to drive or cycle to.

Starred - beautiful beaches.

    But this is your holiday! So get on Google Maps and start planning your adventure...


Grazie mille for reading. Here's a bit of underwater videography:

The Wisdom of Aquatic Crowds

Like humans, fish display much diversity in terms of social behaviour. Some fish prefer to spend time solo.

The Painted Comber likes to hide alone under rocks whilst giving 'side-eye' towards anyone approaching.

Some fish like to hang out with small, diverse groups of compadres.

Are they feeding together or posing for an album cover?

And some fish like to roam the ocean with hundreds or thousands of others just like them.

Homogeneous heroes of the sea.

    There's something very magical about watching a gigantic group of fish zoom past. But what makes fish decide to gather together in shoals or schools, you ask? Even if you didn't ask, I'm still going to tell you. What do you think this post is, a democracy?
  

Shoals vs Schools of Fish


    In order to help you win pointless pub quiz arguments about the differences between shoals and schools, I have provided some very important information about the definitions. 

Shoaling Fish


    Shoaling fish swim together but they do so in directions independent from each other. Being a part of the group doesn't restrict an individual's expression of their identity (ya know what I mean, like). In human terms, they're like one of your most fun social groups - not always the most organised, but you tend to feel energised after spending time with them.  

Damselfish swim together but... slightly apart.

Schooling Fish


   Schooling fish swim together in a coordinated, organised way. It's as if they are all of one mind, one body, but made up of hundreds and thousands of individuals. They're like the hobby social group in which you can achieve impressive things with, but after a while you need some time alone from them. You know, so that you can remember who you actually are and what you really think after detaching from the 'collective'.  

School of European Sprats. Research has found that they don't need no education nor do they need thought control (since the latter comes naturally to them).

    However, to keep things simple I will be referring to schools, shoals or any other gathering of fish as an aggregation.

The Benefits of Aggregation


Fish gain squad-vantages from aggregation, such as:

Strength in Numbers


    A large swarm of homogenous fish all swimming close together can seem like a much larger creature if you're a predator fish (or if your swimming goggles have the wrong prescription). In that way, small fish can group together to intimidate the larger ones.

Left: What I see when I convert a fish aggregation pic to grayscale. 
Right: What a predator fish may see (artists impression).

   Aggregation can also reduce aggression of individual fish towards their own species, even when competing for the same resource. The longer the time spent bonding, the less aggressive fish can be with each other. This phenomena will probably vary across different species, however, and will be dependent on how high-maintenance certain fish friendships can be.

Foodie Friends


    You've heard the phrase 'many hands make light work'. Well, when it comes to aggregating fish, 'many eyes make it easier to locate food'. Admittedly, that could have been catchier. 

You're more likely to be aware of 'that cool new place to eat' when out with your friends than when wandering the streets alone.

    Just like when your friend shouts out 'I've found cake!' and the entirety of your squad then descends upon said cake, when one fish in a aggregation finds food it is communicated to the others via 'feeding movement'. Additionally, you can often find transient groups of fish from different species', co-located, all sharing the same food niche. 

Surmullet fish can form small cliques with other species, united by an appreciation for benthic dishes (e.g. small crustaceans). Can you see the camouflaged turbot dining with them?

There it is.

   However, individual fish in smaller feeding groups or rebellious ones who have broken away from their aggregation can sometimes gain access to food faster than if they'd kept with their crowd.
    
A solo pompano seems to be reflecting on whether it was a good decision to 'go it alone'. More likely though, they're working out how to eat a drowned fly without having to share it with anyone. 

    It's all dependent on those cost:benefit calculations constantly churning away in their tiny aquatic brains. But sometimes I like to think that fish have complex ethical debates with themselves about whether to be selfish or form selfish herds

Stress Reduction


    Some fish are just born sociable - they have no choice but to aggregate, otherwise they'll feel FOMO. Like humans when they bored or miss their friends, fish can indeed feel depression.  

Damselfish in distress.

   Research has shown that if a damselfish is removed from its friends it shows an increase in metabolism and a reduction in physical health. It's always something to consider when building aquariums. If you're displaying fish that naturally aggregate, make sure they have plenty of friends (besides yourself of course).  

Leaders and Followers


   What I find so impressive about aggregations of fish, especially the coordinated schooling species, is that they all seem to 'agree' on which direction to go. Even if there's more than a hundred of them - they all reach a consensus with apparently no bickering or passive aggression. However, in a relatively small group of humans it can seem like an impossible task when deciding where to go for dinner. Schooling fish just 'move' without debate.

'To McZooplankton!' they all said. At once. No complaints.

   There is some debate about how aggregating fish make decisions; is there a leader or is there a 'collective will'? Research suggests that a small group of 'elites' run the show and that body size can affect whether or not fish will 'lead' or 'follow' in shoals of golden shiners. There are both benefits and risks associated with being a leader. Fish at the front often have earliest access to food. In fact, there is a relationship between being a hungry fish and being a leading fish

This hungry striped seabream may as well be the President.

    However, being at the front makes you more at risk of being gobbled up by a predator. In fact, when aggregating fish become frightened, their first instinct is to bury themselves as centrally as possible within their crowd of friends. Interestingly, if a fish becomes injured or shaken it releases a 'fear pheromone', which triggers an escape response in neighbouring individuals. The very Austrian-German biologist Karl Ritter von Frisch named the pheromone 'Schreckstoff' (literally meaning 'fright-stuff'). 

Pictured: Schreckstoff in action (Artist's Impression). Drawing by Rakel Stensmyr from Stensmyr & Maderspacher, 2012.


    'Schreckstoff' itself is a mucus mixture of glycosaminoglycan (GAG) chondroitins (specifically chondroitin-4 and -6 sulphate), and the purified components have been shown to be responsible for the 'fear response' in zebrafish. To be honest, I would be a bit frightened if someone threw mucus at me.  

Final Thought: Crowds vs Individuals


   Many different species of animals group together for the same reasons that fish aggregate. And yes, that definitely includes humans. As 'groups' or 'crowds' of similarly dressed or similarly behaving individuals, humans can accomplish many fantastic things including beautiful traditional dances, large-scale comedic moments and of course, protest marches that can influence the media, current politics and the course of history. Just like fish aggregating, human 'shoals' are that of people gathering together to work towards a goal that is 'bigger' than that of the individual. However, akin to the fish that break away from the collective, it's just as important for humans to recognise when it's better to be an independent thinker or to simply go with the flow.  

    That said, I thought I'd make a little video about crowds both on dry-land and underwater. Hope you enjoy..

How to Make Friends (With an Octopus)

  Friendships are important. Good friendships can be life-saving. However, making friends and maintaining them can be a challenge, especially for those with social anxiety.
    Fortunately there are a lot of helpful online guides and ebooks that can make the whole process a little less daunting. These hints and tips may help to thwart typical barriers to establishing a friendship. Such obstacles can include cultural divisions, language differences, personality contrasts and perhaps even belonging to completely different species'.

1. Search for Friends in the Right Places


   To maximise your chances of meeting future friends; join organizations, clubs or social groups that share the same interests and hobbies as yourself. That way there will be an immediate topic of conversation (or not, if you join a Silence Appreciation Society). Sports clubs or volunteering groups can help you bond with people as you work towards achieving a common goal. However, some fantastic friendships can be formed completely out of the blue due to chance meetings at an opportune moment. 

For example, I was searching ocean caves for food whilst 'Octobob' was hiding in one.

2. Be Friendly, Approachable and Polite


    Don't be afraid to make the first move; reach out to people to show that you want to make friends. Politeness, manners and an understanding of social etiquette can help you make a good first impression. Make sure you're aware of what's culturally normal in terms of personal space boundaries. By being friendly and respecting others' level of comfort, you will seem much less of a threat and absolutely enhance your initial approachability. This is even more important if you're in fact a predator species and Octobob is worried about potentially ending up in a potato salad

The Brits tend to keep a three metre space between them when talking. It's slightly different in the Mediterranean sea, where one metre is probably alright.  

    If you're impolite and get far too close for comfort, it can trigger a 'fight or flight' response in the other person. No one likes arm grabs or unsolicited poking.

3. Make Eye Contact and Sincere Conversation


    During a conversation be sure to show interest in the other person's company. Eye contact, smiling and active responses to what they're saying will mean the other person associates you with a positive interaction. An awareness of the 30% talking/70% listening ratio will mean that the other person is more likely to enjoy the conversation. Negative body language such as repetitive yawning, turning your back or snarling menacingly can have the opposite effect. 

However, extended periods of eye contact can be difficult if the other person has an intense stare or if their eyes are a brilliant shade of orange.

  Sometimes it can be beneficial to communicate with people more than once, but with adequate breaks in between conversations so that they don't view your company as too intense or clingy. It can also help to ward off potential clingy behaviour in the other person. The latter is especially important if your new acquaintance has eight tentacles with the strongest suckers known to science. 

4. Gift Giving


  Gifts don't have to be tangible. Sometimes these can be in the form of compliments, appreciation of their efforts, recognition of their talents or simple acts of kindness. Of course when gifts are tangible, make sure it's appropriate and of a reasonable expense. Specific food items (e.g. a can of chopped tomatoes) can be problematic if you don't know someone's tastes or what they may be allergic to. An elaborate or very expensive gift (e.g. International Space Station Lego Set) can result in awkwardness if you've only known each other for half an hour. From my point of view an Action Camera with a 32GB SD card was an unreasonably expensive gift, as was any of the surrounding fauna.  

Since Octobob seemed to be quite cave-proud, an ornamental beach pebble was thought to be an appropriate and reasonably expensive gift.

5. Be Honest About your Intentions


    Many people can feel suspicious about why they are receiving a gift. Nowadays we're all conscious of bribery and its consequences, so if you do give a gift be sure to communicate your intentions. For example, normal reasons include the celebration of a birthday, wedding or housewarming, or perhaps a thank-you gift if someone has been incredibly awesome. You may also need to state that what you're giving is definitely a gift and not some old junk from your attic or contraband that you're trying to frame them with.  

Communicating clearly is especially important if the other person has slightly blurry eyesight or has difficulty comprehending the human concept of gift giving. 


6. Be Patient


    If you're speaking with someone who has low levels of confidence or if they take a while to trust others, you'll need to be patient. Shyness, fear of rejection or self-consciousness can result in others withdrawing despite you being a perfectly approachable and friendly person. Some people need space and time in order to work out whether or not they trust you or if they feel you're worth investing their time and emotional energy in. 

Some people just fear being hurt by others. Especially if you seem the type to have eaten Insalata di Polpo the previous night.

7. Give them the Chance to Initiate Conversation


  Certain types of people tend to be happiest when they feel they're in control of situations. No one likes to feel forced into anything and it's important to let people choose whether or not they want to engage with your company. Patience and respect can mean that the other person extends their hand (or tentacle) of friendship towards you in good time. 

In some cultures it's polite to shake hands, but note that it's not a universal rule. It may not even be recommended if their 'hand' has incredibly painful suckers. 

8. Enjoy their Company


   If you enjoy social interaction, like-minded others will know this and feel like hanging out with you is fun. Seeing someone emerge from their shell (or crawl out from their cave) and feel comfortable in your presence can be a fantastic feeling. By spending time with them, you may gain a more in-depth understanding of the world, discuss ideas that will initiate thought processes you never thought could exist and learn so much more about others as well as yourself. 
    You may also find out that your friend has some unconventional hobbies, interests or quirks. For instance you may be completely startled by the fact that your new friend looks like an alien brain crawling around on eight giant noodles. Hold back from expressing harsh judgements of their character, however. Remember that no-one is perfect and that we all have our foibles. For example, I probably look like a giant pink alien who only buys cheap tech.  

Octobob may be sociable but I can already sense him judging my camera specs.

9. Let them Introduce you to their Friends


    If they enjoy your company, they may be willing to introduce you to their comrades. Make sure to be genial towards those they care about. Antagonism towards their besties can result in detachment of the friendship quite quickly. Additionally, understand that the dynamic you have with your new friend may be quite different from the type of bond they have with their closer friends. For example, Octobob and his Mediterranean Rainbow Wrasse friend (named 'Red Stripe') will probably discuss Renaissance art whilst snacking on amphipoda

Octobob would have surely been a fan of Bosch and his azurite-rich works

    However, my friendship with Octobob was mainly based on an appreciation of tasteful pebbles. 

10. Respect their Needs


    In order to maintain the friendship, do your best to be a good friend. Initiate meetups, ask the other person how they are, respect their feelings and celebrate their achievements. Even if you feel a little envious that they're able to change the texture and colour of their skin at any given time, be happy for them rather than critically chip away at the attributes that they're proud of. 

Not everyone is blessed with naturally vibrant cyan highlights (it's due to octopus blood containing haemocyanin)

   Importantly, if your friend needs to rest or simply requires their own space (or to hide under ocean reeds), respect their wishes. Compromise and boundary setting is crucial in every social interaction. Understand that everyone has a different threshold for how much time and energy they can spend on socialising. Toxic behaviours such as being too clingy or controlling can cause the friendship to end abruptly. 

11. Understand that Friends Come and Go


   Just like the skin colour of Octobob, friendships are often transient. There is that famous poem which states 'people come into your life for a reason, a season or a lifetime'. Just because you haven't spoken to your friend in ages doesn't mean the friendship is over. However, just because a friendship ends doesn't mean it was necessarily a bad one. Sometimes priorities, circumstances or social needs change. You may need to evaluate your past actions and grieve the loss of the friendship, but don't forget to appreciate the time you spent together and the positive impact it had on your life.
    And anyway, you may still be in contact (and have more in common with) your friend's associates!

'Red Stripe' here is more of a sociable extrovert like myself anyway.

To Octobob!

Who Lives in Rockpools?


Why go 'Rockpooling'?    


    Rockpooling is the third most popular hobby in the UK after wearing shorts in winter and apologising (but not for the shorts). Clambering over rocks and exploring their unpredictable aquariums is a popular family holiday activity and fun for all ages! 
    It happily combines wholesome learning about aquatic wildlife with gaining marine foraging expertise. Both skillsets are incredibly useful and may prepare you and your family for possible future societal collapse.

Also, your dog will enjoy rockpooling too!

  But anyway, let's escape from UK politics for a few minutes and dive into the enchanting world of rockpools themselves. Also, these magic puddles contain their own societies, all with their unique hierarchies, majorities, cultures and divisions.. 

...and all dependent on regular offshore investment.

   So, if you're brave enough to drop into these neighbourhoods...

...and explore their Urban Greenspaces);

...and if you're reckless enough to brave the sub-aqua alleyways...

(As with any alleyway, make sure you avoid the weird people with cameras)

...then these are just some of the curious characters you're likely to meet:

Rockpool Prawn (Palaemon elegans)


  Their exoskeleton may be almost translucent, but what they lack in pigment, they absolutely make up for with personality. 

Left: Shout when you can see them. Right: Shout anyway.

    In fact, science has accused them of having too much personality. If you've ever been rockpooling, you may notice that some of these critters will swim up to you out of sheer curiosity. Although this risk-taking behaviour often results in creepy rockpool prawn selfies, it can put them at a disadvantage. The more cautious of the species tends to do better in terms of access to food.

Sometimes it doesn't pay to be shellfieish.
    
    Their inquisitive nature also means that they are super easy to catch. If you're reading this blog, there's a high probability you've caught one right now, so I may as well tell you that they're edible. Although, before you go ahead and eat hundreds of them at once, it's best I inform you that they often accumulate the environmental pollutant cadmium. Perhaps those prawns are using their media spotlight to tell us to think responsibly about what we're dumping into the ocean

Pictured: Unimpressed prawn

    Although, it's more likely that they're just mesmerised by gigantic fish-eye lenses..

Two-Spotted Goby (Gobiusculus flavescens)?


    It's very difficult to capture a photo of these in the wild, so their identification here is up for debate. Their behaviour includes swimming at 500mph probably. 

Woah, what are those?!

    So, they are small fish, at least we can tell that much.

Oh look there they are!

Wait!

Oh, OK, you're all very busy swimming away. Bye then!

    Whatever these tiny fish are, there's a good chance that they tend to feast on zooplankton (e.g. microscopic shrimp larvae). Zooplankton look incredible under a microscope and according to marine scientists, they are an important indicator of changes to ecosystem health.

Beadlet Anemone (Actinia equina)


    Also known as "what on earth are those slimy red blobs?"

For something we don't know much about, they are sure are everywhere.

  The slimy mucus they secrete is keeping them alive at low tide by protecting them from dehydration. Interestingly, the mucus also has antibacterial and hemolytic activities due to it containing equinatoxins. These molecules help anemones to defend against infectious microbes and to immobilise their prey, respectively. Equinatoxins are produced from venom-secreting cells (or nematocytes/cnidocytes) amidst their tentacles. 

The beadlet anemone 'tentacle fro' is usually only seen when they're underwater.

Equinatoxin Science


  All this talk of toxins sounds quite scary, but they're not dangerous to humans (unless you have a particular allergy to them). In fact, they seem to be of benefit to humans. Equinatoxins have been shown to be effective against human leukaemia and human glioblastoma cells, but also normal fibroblast cells. The highly basic (positively charged) equinatoxin has been extracted and demonstrated to promote the survival of mice with Ehrlich carcinoma.  

Cartoon representation of the X-ray Crystal Structure of Equinatoxin II (Athanasiadis et al 2001PDB: 1IAZ)

  Equinatoxins damage their cellular victims by 'punching holes' (or forming pores) in their membranes. They attach to cell membranes that contain sphingomyelin, which is a type of lipid (or fat) molecule. The toxins then undergo oligomerization, in which a limited number of these molecules group together to form a much larger molecule called an oligomer. It is this oligomer which becomes the 'hole-punch'. 

   X-ray crystallographyNMR (Nuclear Magnetic Resonance) and peptide synthesis techniques have been used to study equinatoxin structures and how they form these pores. This is important work because it's essential that we understand how natural toxins damage cells and how we can best combat them. How equinatoxins interact with membranes is also really interesting from the point of view of those (masochists) who study transmembrane proteins

Rock Gobies (Gobius paganellus), Common Gobies (Pomatoschistus microps), Giant Gobies (Gobius cobitis)


    Rockpools are the ideal habitat for these often well-camouflaged creatures. 

Is it a rock or a goby? It could be both!

    They will often change their appearance to suit their environment. When young they will often be darker in colour and then lighten up to adapt to sandy rockpool environments. 

Tiny baby gobies near a beadlet anenome and limpets. 

    They are often used as bait for fishing the much larger and tastier sea bass. A note of caution; gobies are not as easy to catch as you might think. Any glimpse of a shadow will cause them to dart away to their hiding places, never to be seen again. 

Time was slowed down in order to take these photos..

Blue Mussel (Mytilus edulis)


    As you're probably aware, mussels can be very tasty creatures. You can often find mussels clumped together on rocks at low tide. When picking mussels for your evening meal, make sure you collect the ones that have tightly closed shells at low tide. If you're able to find and eat such live mussels, they are an excellent source of the dietary mineral selenium. 

Mussels find strength by sticking together.

The Science of Byssus Threads


    Mussels aggregate via exceptionally tough byssus threads. These strings of collagenous composites are tougher than our tendons. Byssus threads depend on mfp-1 (aptly named 'mussel-foot protein-1'), a protein that contains a special form of the amino acid tyrosine (DOPA, or 3,4-dihydroxyphenylalanine). DOPA reversibly coordinates with iron ions to further enhance the toughness of byssus threads. Unsurprisingly, these findings are inspiring the development of incredibly tough (and self-healing) industrial and surgical materials.  
    And yes, as you've probably realised - that same amino acid DOPA (also known as L-DOPA or levodopa) is also a precursor to our well-known neurotransmitter dopamine. Isn't science just so unbelievably cool and connects literally everything to everything else just like byssus threads connect mussels to all the other mussels?! I'm sure I'm not the only one that feels like this?! 

European Green Crab/Shore Crab (Carcinus maenas)


    Anyway, back to Rockpooling, which can also be referred to as 'crabbing'. The aim is to find and collect crabs in a bucket of sea-water, then release them back to the wild (or eat them). During my own Rockpool adventures in Cornwall, it took me ages to actually find any crabs. And, well, once I did find them...

I hope they checked themselves for crabs beforehand.

   ...I assumed that they would be pretty pissed off with me if I interrupted them.

    If you're a more successful 'Crabber' than I, then you're very likely to find loads of these Shore Crabs, so make sure you know how to pick them up without getting snipped by their painfully strong claws. Since its Latin name translates to 'mad crab', probably because of its aggressiveness (it will pick a fight with literally anyone) and since its pincers are tough enough to crush oyster shells you'll want to protect your fingers.


Rockpooling and Cornwall Travel Advice


    So, if you want to meet these interesting Rockpool characters, wear your Winter shorts, get some beach shoes and fill up a bucket with bait (bacon strips work well). Just make sure that bucket has a lid, otherwise it will attract the interest of militant seagulls

Or your fluffy and very helpful hunting companions...
  
   And if you're visiting Cornwall, (also known as Kernow) make sure you check the tide timetable before Rockpooling. If you're searching for your dinner at the beach, then chons da (that's Cornish for good luck). If you don't catch anything, you can always treat yourself to the local delicacy - the famous Cornish Pasty
