Superfamilies

Astacidea is a group of decapod crustaceans including lobsters, crayfish and their close relatives. It comprises four superfamilies, two of crayfish (Astacoidea and Parastacoidea), one of true lobsters (Nephropoidea), and one of reef lobsters (the genus Enoplometopus).

All about lobsters (1054 words)
the Astacidea (marine lobsters and freshwater crayfishes), Palinuridea (spiny and slipper lobsters), and Thalassinidea (mud lobsters).
The infraorder Astacidea contains three superfamilies: the Nephropoidea (the commercially important marine lobsters) and the Astacoidea and Parastacoidea (freshwater crayfishes of the northern and southern hemispheres, respectively).
Lobsters and crayfishes of the infraorder Astacidea are distinguishable from other lobsters because they bear pincers (or chelae) on the first three pairs of legs.
Group: Shrimps (657 words)
The shell (or exoskeleton) must be replaced during growth, this process is named molting.
Decapoda includes many different suborders (Penaeidea, Stenopodidea, Caridea, Astacidea, Palinuridea, Thalassinidea) also known as a whole as Macrura (large tail).
These are what commonly we call shrimps, prawns, lobsters.
