Xenoturbellidae
A family of simple, worm-like marine animals classified as basal deuterostomes. Used in zoological and taxonomic contexts.
Organisms belonging to the family Xenoturbellidae live in deep-sea mud.
The Japanese name 珍渦虫科 is a direct translation of the scientific family name Xenoturbellidae, combining 珍 (strange), 渦 (whirlpool), 虫 (worm), and 科 (family). The derivation is taxonomic rather than historical.
