What defines this group — Crustaceans
Armoured arthropods: crabs, shrimp and lobsters, all built around an external shell.
- The skeleton is on the outside; growing means shedding it — the moult.
- Jointed legs in pairs, often reshaped into claws or antennae.
- The larvae drift with the plankton in open water before settling on the bottom.
