What is the name of a small marine crustacean?

Answer 1

The class Crustacea comprises the majority of the marine species of the arthropods, although there are many freshwater species and even a few terrestrial ones such as the common sowbug. The most familiar are shrimps, crabs, and lobsters, but the diversity of the crustaceans in form and biology ranges from the gigantic king crab of the Pacific Ocean to a myriad of planktonic forms comprising the dominant herbivores of the ocean.
