Crustaceans

We can all recognise a crustacean.

They include lobsters, crabs, shrimp and woodlice. Crustaceans all have hard exoskeletons and jointed legs that they use to swim, walk or dig. Small shrimp and other crustaceans are an important food source for fish and other animals, including humans.

Crab Lobster Wodlouse
Crabs, lobsters and woodlice are all crustaceans.

Crustaceans are also important fossils. The oldest fossil crustaceans are found in Cambrian rocks formed over 500 million years ago. Many of the fossil crustaceans we find in England are from the Jurassic period, and look very much like the shrimp, crabs and lobsters we see today.
