Xenoturbellida
A phylum of simple, worm-like marine animals classified as basal deuterostomes. Used in biological taxonomy.
Organisms belonging to the phylum Xenoturbellida live in the mud on the seafloor.
The name 珍渦虫門 is a Japanese taxonomic coinage combining 珍 (rare, strange), 渦 (whirlpool, vortex), 虫 (worm, insect), and 門 (phylum). The derivation is uncertain; it likely reflects the unusual morphology and marine habitat of these organisms.
