Taxonomy
This page represents the following TreeOfLife-200M taxonomic path.[1]

- Class: Hexactinellida
- Order: Lyssacinosida
- Family: Rossellidae
- Genus: Anoxycalyx
Visual Description
Anoxycalyx (Rossellidae) is a hexactinellid glass sponge; available imagery for the genus commonly shows a three-dimensional, siliceous skeleton with a rigid, macroscopic body form, consistent with other Rossellidae lyssacinosids.
Nomenclature and taxonomic status
Anoxycalyx Kirkpatrick, 1907 is treated as an accepted genus-level taxon in GBIF.
Ecology and life history (key example: Anoxycalyx joubini)
Long-term monitoring in McMurdo Sound (Antarctica) has been used to reassess life-history expectations for Anoxycalyx joubini, a dominant, structure-forming hexactinellid sponge in that region.
Findings from this work emphasize that demographic processes can be episodic: over multi-decade intervals, recruitment and measurable growth may be minimal, followed by a period of settlement and rapid growth after conditions improve.
The study also reports very high mortality of large individuals during later phases within the monitoring window, and discusses how physical disturbances (e.g., ice-related damage) and biological interactions may contribute. The authors link the recruitment-and-growth episode to a region-wide shift in food availability driven by changing ice dynamics.
Biotic interactions
Evidence from Global Biotic Interactions indicates that Anoxycalyx (reported in records at least for A. (Scolymastra) joubini) can be preyed upon by other benthic animals, including echinoderms (e.g., ophiuroid/asteroid taxa in the dataset records).
