(^4) LOBSTER
Weighed down by their heavy shells,
lobsters usually walk on the sea floor,
but they can swim backwards to
escape danger by flipping their tails.
Like all crustaceans, they have to
moult (shed) their hard exoskeletons
several times as they grow.

(^5) WOODLOUSE
Woodlice are among the only
crustaceans that are completely at
home on land, but they must live in
damp places. They have seven pairs of
legs and some species can roll themselves
into a ball if they feel threatened. Despite
their name, they do not damage wood.
(^6) PRAWN
Many prawns and shrimps swim or
drift in the water, but others spend
most of their lives searching for food
on the sea bed. Some specialize in
picking bloodsucking parasites off
the fish that live on coral reefs, which
queue to be cleaned up.
