The crustacean group is usually treated as a subphylum, and because of recent molecular studies it is now well accepted that the crustacean group is paraphyletic, and comprises all animals in the Pancrustacea clade other than hexapods.

The 67,000 described species range in size from "Stygotantulus stocki" at , to the Japanese spider crab with a leg span
