crustacean

Ecdysozoans include all the arthropods, including insects, crustaceans, and spiders, as well as tardigrades, and roundworms, or nematodes.

It uses a cavernous hood to trap crustaceans to eat — a feeding strategy also used by anemones and some jellies.

But as transport networks made travel easier and food storage improved, more and more people were introduced to the crustacean.

For example, they’ve witnessed people wading into the water in the tidepools, a sensitive habitat that’s home to a variety of sea life, including octopus, urchins, sea stars, crustaceans and small fish.

Shipments that comply with U.S. law are safe — but not all shipments do, said Julie Lively, a crustacean expert and associate professor at the Louisiana State University AgCenter.
