Crabs are found in all of the world's oceans, while some varieties do live in freshwater or land. There are more than 6,000 known species, but not all of them are edible! Decapods, meaning '10-legged', refer to crabs, lobsters and shrimp.
Crabs are famous for their sideway struts! :) They are scavengers and can survive extreme living conditions.
The tiniest Pea Crab is only a few millimetres wide while the Japanese Spider Crab, has a leg span of up to 4 m!
