Euplectellidae
Euplectellidae is a family of glass sponges (Hexactinellids) belonging to the order Lyssacinosa Lyssacinosida (also spelled Lyssacinosa) is an order of glass sponges (Hexactinellida) belonging to the subclass Hexasterophora. These sponges can be recognized by their parenchymal spicule (sponge), spicules usually being unconnected, unlike in ..., first represented in the Ordovician fossil record, substantially older than molecular estimates of the clade's age. Taxonomies According to the World Register of Marine Species (WoRMS) the family includes the following subfamilies and genera: Subfamily Bolosominae Tabachnick, 2002 * '' Advhena'' Castello-Branco, Collins & Hajdu, 2020 * '' Amphidiscella'' Tabachnick & Lévi, 1997 * '' Amphoreus'' Reiswig & Kelly, 2018 * '' Bolosoma'' Ijima, 1904 * '' Caulocalyx'' Schulze, 1886 * '' Hyalostylus'' Schulze, 1886 * '' Neocaledoniella'' Tabachnick & Lévi, 2004 * '' Rhizophyta'' Shen, Dohrmann, Zhang, Lu & Wang, 2019 * '' Saccocalyx'' Schu ...

Lyssacinosa
Lyssacinosida (also spelled Lyssacinosa) is an order of glass sponges (Hexactinellida) belonging to the subclass Hexasterophora. These sponges can be recognized by their parenchymal spicule (sponge), spicules usually being unconnected, unlike in other sponges in the subclass where the spicules form a more or less tightly connected skeleton.''Treatise on Invertebrate Paleontology'' Part E, Revised. Porifera, Volume 3: Classes Demospongea, Hexactinellida, Heteractinida & Calcarea, xxxi + 872 p., 506 fig., 1 table, 2004, availablhere . Lyssacine sponges have existed since the Upper Ordovician, and three families (four including Aulocalycidae) are still alive today. The Venus' flower basket (''Euplectella aspergillum'') is one of the most well-known and culturally significant of the glass sponges. Subgroups * Family Aulocalycidae?
