Crabs and Their Relatives

 Common Hermit Crab

 The Hermit Crab has no shell of its own to 
protect its body,so it finds an empty shell to 
live in. When it outgrows the shell, it finds
 a new one. It can be found in rock pools.

Common Lobster

Small Common Lobsters are sometimes 
found in rock pools on the lower shore.
Most lobsters, though, crawl along the
seabed in deep waters.

Edible Rock Crab

 Large Edible Rock Crabs live in deep water, 
but you can see small ones in rock pools, 
under rocks or buried under the sand on
the lower shore. As you can guess from
their name, these crabs can be eaten. 

Squat Lobster

This is not a true lobster, but a relative.
It is found under rocks and stones on the
lower shores. Its first pair of walking 
legs have very long pincers.

Sea Lice

 For this animal, look in breakwaters and on rocks
above the high tide level on the upper shore. 
It is nocturnal - it comes out at night to feed.

It has broad, flattened claws on its front legs. 
People catch shrimps and prawns to eat.

Acorn Barnacle

 Barnacles stick to rocks and build a hard shell
around themselves, like a wall. They are a very 
common sight on rocks. The Acorn Barnacle
has a diamond-shaped opening.

Common Prawn

 This creature is common in shallow water
and you can sometimes find it in rock
pools. Like all prawns and shrimps,
its feelers are longer than its body.
