Crabs
have five pairs of jointed legs. If a crab looses a leg it can grow a
new one.
Crabs
eyes are carried on stalks. Some crabs have long eye stalks and
others are very short.
Crabs
breathe with gills. They take water in to the gill chamber under the
carapace through pairs of slits near the base of their legs. Water
passes out through openings in the mouth frame.
As
crabs grow too big for their skeleton they moult. The skeleton splits
and the crab carefully edges its way out. Its new soft skeleton is
underneath.
Crabs
have to be very careful at this time in case their predators find
them.
