Abstract

A new species of corallivorous goniasterid, Evoplosoma watlingi n. sp., from Bear Seamount in the North Atlantic is described in conjunction with an overview of other species within the genus Evoplosoma. Hippasteria tasmanica McKnight, 2006 is re-classified within Evoplosoma. In situ images of Atlantic deep-sea Goniasteridae, including Evoplosoma spp., Hippasteria phrygiana and Circeaster americanus, are presented herein. Observations of several Evoplosoma species and the Atlantic C. americanus are documented for the first time, recorded by the R/V Okeanos Explorer. The feeding duration of C. americanus is also documented for the first time.
