Agelas citrina
Taxonomy
This page represents the following TreeOfLife-200M taxonomic path.[1]
- Kingdom: Animalia
- Phylum: Porifera
- Class: Demospongiae
- Order: Agelasida
- Family: Agelasidae
- Genus: Agelas
- Species: Agelas citrina
Visual Description
Agelas citrina is a marine demospongian sponge. Photos/specimen records under this taxon show a generally low-profile, cushion-like to encrusting habit with a yellow–orange (“citron”) appearance, consistent with the species epithet and vernacular naming (e.g., “Citron Sponge”).
Species identity and nomenclature
Agelas citrina Gotera & Alcolado, 1987 is treated as an accepted species in occurrence databases, associated with the English name “Citron Sponge.”[2]
Chemistry and notable metabolites
A well-characterized aspect of Agelas citrina is its production of pyrrole–imidazole alkaloids (PIAs). Cychon et al. report discovery of four new citrinamines (citrinamine A–D) and the related alkaloid N-methylagelongine from this sponge.[3]
The study describes the citrinamines in the context of PIA dimer structures and details analytical approaches used for structural elucidation (e.g., high-resolution mass spectrometry and NMR methods).[3]
