Rossellidae (Porifera: Hexactinellida) from the Bering Sea and off Bering Island

Abstract

Members of the family Rossellidae are the main contributors to the hexactinellid fauna and even to the macrobenthic fauna in the deep waters of the North Pacific. Representatives of this family often reach a larger size than other Hexactinellida, Porifera and even other representatives of benthic invertebrates. Description of Rossellidae from the Bering Sea collected by trawls, submersibles and remotely operated vehicles (ROVs) during the expeditions of RVs 'Akademik M.A. Lavrentyev' and 'Akademik Mstislav Keldysh' are given. Subgenera, species and subspecies in five genera are described and include: Acanthascus (Acanthascus) alani profundus; A.

Expanded sampling of New Zealand glass sponges (Porifera: Hexactinellida) provides new insights into biodiversity, chemodiversity, and phylogeny of the class

“… *** Sequences obtained from other specimen(s). a During the production stage of this article, we became aware of the publication by Tabachnick, Menshenina & Ehrlich (2023) , who abolished the subfamilies of Rossellidae. While we principally support this move, we wish to point out that Lanuginellinae remains valid as a phylogenetic group (clade), given its strong molecular support (see also Dohrmann et al., 2017 : p. 27 for a morphological diagnosis).…”
