Hexactinellida genera

Euplectella is a genus of glass sponges which includes the well-known Venus' Flower Basket. Glass sponges have a skeleton made up of silica spicules that can form geometric patterns. These animals are most commonly found on muddy sea bottoms in the Western Pacific and Indian Oceans. They are sessile organisms and do not move once attached to a rock. They can be found at depths between 100 m and 1000 m but are most commonly found at depths greater than 500 m.

Bolosoma is a genus of pedunculated siliceous sponges belonging to the family Euplectellidae. This genus lives in deep-sea environments and provides a habitat for a plethora of other benthic species, giving Bolosoma an incredibly important ecological role in the ecosystems it is a part of. thumb|Brittle stars and other deep-sea invertebrates use this Bolosoma species as a habitat

Lefroyella is a genus of glass sponges in the subfamily Euretinae, containing 2 species.

Staurocalyptus is a genus of sponge. It was circumscribed in 1897 by Isao Ijima.

thumb Monorhaphis is a monotypic genus of siliceous deep sea Hexactinellid sponges. The single species is the type species Monorhaphis chuni, a sponge known for creating a single giant basal spicule (G.B.S.) to anchor the sponge in the sediments. The species was described by Franz Eilhard Schulze in 1904 from specimens collected by the German Deep Sea Expedition in 1898–1899. Monorhaphis is also the only genus in the monotypic family Monorhaphididae.

Hyalostylus is a genus of sponges belonging to the family Euplectellidae.

Aspidoscopulia is a genus of glass sponge in the family Farreidae.

Atlantisella is a genus of glass sponges (Hexactinellids) belonging to the family Euplectellidae, first described in 2002 by Konstantin Tabachnick.

Lonchiphora is a genus of glass sponge in the family Farreidae.

Claviscopulia is a genus of glass sponge in the family Farreidae.

Sclerothamnus is a genus of glass sponges in the family Tretodictyidae.
