*HINTS:

Crustaceans have no backbone, but have a hard exoskeleton. The body is divided into segments and they grow by molting their exoskeleton periodically.
-
They have gills
-
Crustaceans have three body parts: head, thorax and abdomen (the head and thorax are often fused together)
-
On their head, they have two compound eyes (some can also have one median simple eye in their larval stage), two pairs of antennae and three pairs of mouthparts
-
On their thorax, crustaceans have four pairs of walking legs and one pair of claws
-
On their abdomen, they have swimmerettes (swimming legs) which are paddle-like
-
The circulatory system is open and there is no heart
