Crustaceans

Crustacea is a large group of animals, and comprises an extensive range of marine creatures. It is impossible to give them a generalised physiology as crustacean forms vary widely and includes the barnacles, crabs, lobsters, shrimps, prawns, sand hoppers and sea slaters. As demonstrated by this list, no simple definition would encompass all these body types.


CRABS	PRAWNS & SHRIMPS	AMPHIPODS


Locally found crab species. Their bodies come in different shapes and sizes.	Prawns are common transparent creatures. Shrimps have more colour.	A group of small creatures, that include the immensly common sand hoppers.

ISOPODS	BARNACLES	LOBSTERS


A group of small creatures, that include the fast moving common slater.	Such small animals could easily overlooked, but due to sheer numbers this is not so.	Lobsters use their legs to move, but canl rapidly swim backwards using their fan shaped tails.
