0:05:06 > 0:05:08We're down here today to do some rock-pooling.
0:05:08 > 0:05:11- So, Jack, what have you found? - We have found a pie crust crab,
0:05:11 > 0:05:15which can grow to an unbelievable size and can also be eaten.
0:05:15 > 0:05:18Oh, look, there he is! We've actually got two in there!
0:05:18 > 0:05:22So, you can see there, Karen, the pie crust shape on the shell.
0:05:22 > 0:05:25- And that's what's Jack's talking about.- Just like a Cornish pasty!
0:05:25 > 0:05:29Exactly right. And they also do grow really, really big
0:05:29 > 0:05:33and that's why we eat them - because their claws are full of flesh.
0:05:33 > 0:05:36So, they're very popular round here and all around the world to eat.
0:05:36 > 0:05:38Nola, what have you found? What did you like?
0:05:38 > 0:05:43Well, one of the best things is the butterfish, which is hard to find.
0:05:43 > 0:05:47- But it's pretty fun to watch it swim around so fast.- Which one?
0:05:47 > 0:05:49- Have we got one in there?- Yeah, we've got a couple in here.
0:05:49 > 0:05:53There's one absolutely gorgeous orange-coloured one.
0:05:53 > 0:05:57They get their name because they're really slippery, like butter.
0:05:57 > 0:06:00But they're very special because they can survive
0:06:00 > 0:06:04on the coastline here without water for quite a long time.
0:06:04 > 0:06:08So, the slimy coating over their skin actually provides moisture
0:06:08 > 0:06:09for their gills,
0:06:09 > 0:06:12which helps them breathe when they're in the dry.
0:06:12 > 0:06:14And they're always mistaken for eels.
0:06:14 > 0:06:17So, if you find what looks like an eel,
0:06:17 > 0:06:19but has spots on its side, it's definitely a butterfish.
0:06:19 > 0:06:23- OK, what else have we got? - OK, so we've got lots of limpets.
0:06:23 > 0:06:25We've got some anemones.
0:06:25 > 0:06:27But I'm actually going to have a wee go myself.
0:06:27 > 0:06:30- And maybe get your hands a bit dirty?- Absolutely!
0:06:30 > 0:06:32- If you want to help me move back some of this seaweed?- Uh-huh.
0:06:32 > 0:06:39- And see what we can find... Let's see what we've got.- Oh, look!
0:06:39 > 0:06:41Yeah, we have a starfish.
0:06:41 > 0:06:44So, this is a common starfish.
0:06:44 > 0:06:46They are absolutely common here.
0:06:46 > 0:06:48You'll probably find one nearly every time you come down
0:06:48 > 0:06:51to the beach. They get a lot bigger than this
0:06:51 > 0:06:54but the shoreline is a perfect spot for finding baby starfish.
0:06:54 > 0:06:57- They're quite rough little suckers on there, yeah?- Yeah.
0:06:57 > 0:07:00- I'll just pass it over to you. And I can turn him over.- Oh!
0:07:00 > 0:07:04So, underneath here we've got hundreds of little feet
0:07:04 > 0:07:08and they move around individually and have little suckers on the end.
0:07:08 > 0:07:11So, that's how starfish can stick to rocks.
0:07:11 > 0:07:13But it also helps them when they're feeding.
0:07:13 > 0:07:17So, what they do is they find a piece of food, like a shellfish,
0:07:17 > 0:07:20or a piece of fish, anything they can find,
0:07:20 > 0:07:23that's usually quite smelly, and they sit on top of it
0:07:23 > 0:07:26and pull the shellfish open with these sticky feet.
0:07:26 > 0:07:28And then they do something pretty gross.
0:07:28 > 0:07:32- They spit their stomach out on top of their food.- Ah!
0:07:32 > 0:07:34There's not much room in there,
0:07:34 > 0:07:38which means they have to digest all the food outside of their body.
0:07:38 > 0:07:40- Not such a pretty starfish.- No.
0:07:40 > 0:07:43And when they're finished, it turns into a big fish soup
0:07:43 > 0:07:46and they suck it all back in again. So, it's not very pleasant
0:07:46 > 0:07:49but it's the way they have to do it to survive.
0:07:49 > 0:07:51- He has terrible table manners!- Yes!
0:07:53 > 0:07:56Well, Lewis, what have you found?
0:07:56 > 0:07:59- I found a sea anemone. - A sea anemone?
0:07:59 > 0:08:03Very good. And he's stuck to the rock. That's what they do, isn't it?
0:08:03 > 0:08:08So, a sea anemone is basically an upside-down jellyfish.
0:08:08 > 0:08:13And, you know when they're under the water, all their red tentacles come out.
0:08:13 > 0:08:15This one's called a beadlet anemone.
0:08:15 > 0:08:19And all around the outside, he's got little blue tentacles,
0:08:19 > 0:08:22which he uses for fighting with other anemones.
0:08:22 > 0:08:25And I see you've got a limpet here as well?
0:08:25 > 0:08:27And these are also stuck to the rock.
0:08:28 > 0:08:33So, did you know that limpets actually leave their little spot
0:08:33 > 0:08:36in the rock whenever the tide comes up?
0:08:36 > 0:08:40And when they go away, they leave a little trail of scent behind,
0:08:40 > 0:08:44so that they can find their way back when the tide goes out again.
0:08:44 > 0:08:47And that means they always stay in the same spot.
0:08:47 > 0:08:50So, if you see a rock with a dark circle in it,
0:08:50 > 0:08:53that's called a limpet scar - and that's where the limpet lives.
0:08:53 > 0:08:55So, he always comes back.
0:08:55 > 0:08:58Jen, Lewis and David are loving all of this.
0:08:58 > 0:09:00And we've got to remember, haven't we,
0:09:00 > 0:09:02- that this stuff can be found on any rocky shore?- Yeah.
0:09:02 > 0:09:05And every rocky shore will have a different set of animals.
0:09:05 > 0:09:07So, you'll never get bored!
