General description
Aporodoris is a genus of dorid nudibranchs, which are shell‑less marine gastropod molluscs. Members of this genus are part of the family Discodorididae, a group characterized by a broad, often flattened body, a mantle covered with caryophyllidia (small tubercles), and gills arranged around the posterior part of the dorsum. As with other discodoridids, species of Aporodoris are benthic predators, typically feeding on sponges.
Recognized species
The taxonomic status of species within Aporodoris has been subject to revision, and the number of currently accepted species may vary among databases. A widely referenced species historically placed in the genus is:
- Aporodoris millegrana (Cuvier, 1804) – reported from temperate Atlantic waters, notably around the British Isles and the Mediterranean Sea.
Other nominal species have been synonymised or reassigned to related genera (e.g., Jorunna, Discodoris) in recent systematic works. Readers are advised to consult up‑to‑date taxonomic references for the latest species list.
Distribution and habitat
Records for Aporodoris species indicate a primarily Northeast Atlantic and Mediterranean distribution, inhabiting subtidal zones from shallow coastal waters to depths of several tens of meters. They are commonly found on rocky substrates or among sponge‑rich communities where they can locate their preferred prey.
Taxonomic notes
- The genus Aporodoris was originally established in the late 19th century (the exact author and year are recorded in the original description; primary literature should be consulted for precise citation).
- Molecular phylogenetic studies of the Discodorididae have prompted re‑examination of generic boundaries, resulting in some former Aporodoris species being transferred to other genera.
