Mobile homeThis hermit crab dragsits home wherever itgoes. It finds a shell tolive in, then hides insidewith just its head andfront legs poking out.

This shell once belongedto a whelk. It was just theright size, so I moved in.


This hermit crab’s bodyreaches up to 10 cm (4 in) in length. As itgrows, it findslarger shells to move into.

pincer to nip an attacker.

Mmm, a deadfish - just what I fancy for mybreakfast.

turns white, and if it is angry it

turns blue.

Feeling my wayThis strawberry shrimp lives on a coral reef, hiding amongthe corals or in a burrow inthe sand. Its long feelers, or antennae, help it to find food.

I use my claws forpicking up food anddigging in the sand.If I lose a claw, I cangrow another one.

Crusty crabScuttling around a rockpool, a pie-crust crab islooking for food. It gets itsname from the top partof its shell, which lookslike the pastry on a pie.






The colours of my shellhelp me to hide amongthe pebbles.

I have two hugepincers forgrabbing my food.

An adult pie-crust crabmeasures about15 cm (6 in)

across its shell.That’s about the size of your hand.

Snappy shellsLying on the seabed, a group of queen scallops are waiting fortheir next meal to float past. Theytrap tiny plants in the wavinghairs around their shells.

Did you know...

counting the ridgeson its shell. Themore ridges, the

older it is.


I swim along by opening andshutting my shell, a bit likeyou clapping your hands.
