Beyond their role as a luxury seafood resource, crustaceans are central to modern research. is the formal study of crustaceans , with major publications like the Journal of Crustacean Biology dedicated to their biology, genetics, and evolution. Recent legal and scientific discussions in regions like the UK have even explored crustacean sentience and animal welfare standards.

While they vary immensely in shape and behavior, most crustaceans share several defining biological traits:

: Sessile (fixed-in-place) sea creatures that attach to rocks, boats, or even whales . Scientific & Human Importance
