}}Tantulocarida is a highly specialised group of parasitic crustaceans that consists of about 33 species, treated as a subclass of the class Maxillopoda (copepods and barnacles). They are typically ectoparasites that infest copepods, isopods, tanaids, amphipods and ostracods.[2]

Description

{{expand section|date=June 2018}}

==={{anchor|Body size}}Body length===

Members of this subclass are minute – less than {{convert|0.3|mm|in}} in length and have a dramatic reduction in body form compared to other crustaceans, with an unsegmented, sac-like thorax and a much reduced abdomen.[3] One tantulocarid species, Tantulacus dieteri, is the world's smallest arthropod, with a total body length of only {{convert|85|um}}.[4]

Life cycle

{{expand section|date=June 2018}}

The tantulocarid life cycle is unique. It does not follow the usual moulting cycle of all crustaceans; instead, the mature adult actually develops within an attached parasitic tantulus larva.[5]

Classification

Five families are recognised:[6]
