Atubaria heterolopha explained

Atubaria heterolopha is a species of hemichordates in the monotypic genus Atubaria and in the monotypic family Atubaridae. This taxon belongs to the pterobranchian order Cephalodiscida. It was described by Tadao Sato in 1936[1] from specimens found feeding on a colony of the hydrozoan Dycoryne conferta in Sagami Bay, Japan.[2]

Description

The characteristics of this pterobranch species include a 1–5 mm long zooid, a collar with four pairs of tentaculated arms, a single pair of pharyngeal slits, and a solitary and sedentary behaviour.[3] It closely resembles Cephalodiscus members.[4]
