This page represents the following TreeOfLife-200M taxonomic path.[1]
Images in the TreeOfLife-200M dataset show specimens identified as Acanthascus (Rossellidae, Hexactinellida). These images typically depict thin, branching/supple sponge structures with a delicate, glass-spicule–like look rather than massive, thick tissues. Observations are consistent with a hexactinellid growth form in which skeletal elements are prominent and overall silhouettes can appear filamentous or lacy in photographs.
Molecular phylogenetic analyses of Porifera that incorporate complete SSU rRNA secondary-structure information have been applied across the three extant sponge classes, including Hexactinellida (the class containing Rossellidae and Acanthascus). These approaches use rRNA structural models to improve alignment and phylogenetic reconstruction accuracy for deep metazoan relationships. [3]
