Brit.

/ˌɡastrə(ʊ)ˈtrʌɪkə/, U.S.

/ˌɡæstrəˈtraɪkə/

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

Etymology: < scientific Latin Gastrotricha ( E. Mečnikow 1865 , in Zeitschrift f. wissenschaftliche Zoologie 15 458) < gastro- gastro- comb. form + < ancient Greek τριχ- , θρίξ hair (see tricho- comb. form¹) + scientific Latin -a -a suffix².

Zoology.

With plural agreement: a small phylum of minute aquatic invertebrates having a short worm-like body bearing cilia, bristles, and posterior adhesive organs; (also) animals of this phylum (collectively or individually).The Gastrotricha are thought to be related to rotifers and nematodes, and they were formerly regarded as a class of the phylum Aschelminthes.
