Memoirs of the Queensland Museum 44: 289–298. Hexactinellids modify the substratum through spicule deposition, providing a substratum (Barthel 1992) and enable diatom colonization, enhanced by the optical conveying. The order Poecilosclerida is the most species-rich in the antarctic and subantarctic regions. 273: R100-R106.

Barthel D, Gutt J (1992) Sponge associations in the eastern Weddell Sea. Abstract \ud \ud This paper presents an idea on the possible structuring effect of hex actinellids on Antarctic sponge associations. As a result, there have been no comprehensive phylogenetic studies of extant hexactinellid taxa or molecular phylogenetic analyses of intraclass relationships published to date. Polar Biology 8: 367–376. ; Schönberg, C. Validum Edit to include features of both the N Atlantic and Antarctic specimens. Antartic Hexactinellida - Barthel

Most of the world’s continental margins are incised by submarine canyons. Grassé, P. Sponges in Antarctica and in the North Atlantic have been found to play an important role in increasing local biodiversity by offering a substrate for the settle-ment of other invertebrates (Barthel & Gutt 1992, Bett & Rice 1992).
