discussion
This species was recognized based on its weakly stellate shape, marginal plate series and surface spination. This represents the first report of this species alive and apparently feeding on a hexactinellid sponge. Some doubt has long been applied to the status of Marginaster, which has been considered as either a small adult poraniid or the juvenile form of an unknown adult poraniid (summary in Mah & Foltz 2012). The latter hypothesis has been difficult to confirm owing to the apparent absence of observed adult poraniid taxon co-occurring in the same region as Marginaster spp. Porania pulvillus has not previously been observed this far south and could suggest a possible taxon for testing the latter hypothesis to verify Marginaster ’ s identity. Identification of this species has been made under the assumption of the former notion that Marginaster is an adult.
