Tardigradan.

Brit.

/ˈtɑːdᵻɡreɪdə/, U.S.

/ˈtɑrdəˌɡreɪdə/

Origin: A borrowing from Latin. Etymon: Latin Tardigrada.

Etymology: < scientific Latin Tardigrada (see quot. 1842) < post-classical Latin tardigradus (see tardigrade n. and adj.) + scientific Latin -a -a suffix², after Italian tardigrado ( L. Spallanzani Opuscoli di fisica animale, e vegetabile II. (1776) 224).

Zoology.

With plural agreement: a phylum of minute aquatic invertebrates, many of which live in the water film on the surface of mosses, characterized by a short stout body, a chitinous cuticle, and four pairs of stubby non-jointed legs bearing claws or ‘toes’. Also: animals of this phylum (collectively or individually); water bears.The taxonomic position of the Tardigrada is uncertain, but they are thought to be allied to the arthropods and were formerly regarded as a subclass of arachnids. They are noted for their ability to withstand extremes of heat, cold, and desiccation by becoming dormant.
