Multicrustacea
Temporal range: Middle Cambrian–Present
A diversity of different crustaceans, a group of segmented animals: Sally lightfoot crab (Grapsus grapsus), European lobster (Homarus gammarus), Red swamp crayfish (Procambarus clarkii), Pacific cleaner shrimp (Lysmata amboinensis), Antarctic krill (Euphasia superba), Hemilepistus reaumuri, Calanoida, and Pelagic gooseneck barnacle (Lepas anatifera).

Classes

The clade[1][2][3][4] Multicrustacea constitutes the largest superclass of crustaceans, containing approximately four-fifths of all described crustacean species, including crabs, lobsters, crayfish, shrimp, krill, prawns, woodlice, barnacles, copepods, amphipods, mantis shrimp and others. The largest branch of multicrustacea is the class Malacostraca (see below).

Classification

Superclass Multicrustacea Regier, Shultz, Zwick, Hussey, Ball, Wetzer, Martin & Cunningham, 2010 [5]


Notes:

  1. ^ a b Class Hexanauplia Oakley, Wolfe, Lindgren & Zaharof, 2013 was proposed for copepods and thecopods, but not supported by subsequent studies.[6]

Fossil record

This section needs expansion. You can help by adding to it. (December 2023)

The earliest fossils representative of Multicrustacea are from the Cambrian.[8] However, the more specific timeline is uncertain. Some Cambrian fossils of uncertain taxonomic placement, such as those of Priscansermarinus, are nonetheless likely to be members of Multicrustacea.[citation needed]
