Taxonomy
This page represents the following TreeOfLife-200M taxonomic path.[1]
- Kingdom: Animalia
- Phylum: Porifera
- Class: Demospongiae
- Order: Tetractinellida
- Family: Theneidae
- Genus: Annulastrella
Visual Description
TreeOfLife-200M-derived dataset images associated with this genus show preserved museum specimens identified to Annulastrella ornata (Naturalis Biodiversity Center records; photographed preserved material).
Distribution and data availability
GBIF lists Annulastrella (as Annulastrella Maldonado, 2002) as an accepted genus and provides taxon-graph metrics through its genus page.
NCBI taxonomy places Annulastrella within Porifera → Demospongiae → Tetractinellida → Theneidae.
Phylogenetic context (Astrophorida spicule homoplasy)
Molecular phylogenetic work on Astrophorida (within which Tetractinellida lithistid-type lineages such as Theneidae are included) indicates that morphological characters based on spicules can show substantial homoplasy (convergence and/or secondary loss), which can contribute to discordance between DNA-based relationships and traditional classifications.
