Dendronotus

Lore & Background

Dendronotus has an elongated, broad body with 4 to 8 pairs of branched cerata on the notum. Animals in this genus have an obvious oral veil with 2 to 5 extensions, which may be branched, and smaller unbranched extensions around the mouth. The rhinophores are surrounded by a sheath that itself has branched extensions, and a large extension is found on the side at the base of each rhinophore. The anal opening occurs between the first and second set of dorsal cerata on the right side of the body.

This genus feeds on hydroids, as reflected by its serrated radula. The article lists numerous species within the genus, including Dendronotus albopunctatus, Dendronotus albus, Dendronotus arcticus, and many others, along with several species brought into synonymy such as Dendronotus diversicolor (synonym of Dendronotus albus) and Dendronotus luteolus (synonym of Dendronotus frondosus).

Reader's Guide

The significance of Dendronotus lies in its distinctive morphology and its placement within the superfamily Tritonioidea and clade Cladobranchia. The genus is characterized by its branched cerata, oral veil extensions, and rhinophore sheaths with branched extensions, which are key features for identification. Its diet of hydroids, indicated by a serrated radula, reflects its ecological role. The extensive list of species and synonyms provided in the article demonstrates the taxonomic work done on this genus, including contributions by researchers such as Robilliard, MacFarland, Korshunova, Martynov, and others. The inclusion of synonyms like Dendronotus diversicolor and Dendronotus luteolus highlights historical taxonomic revisions. The article also references external SEM images of the radula from Thompson & Bebbington (1973), which aid in understanding its feeding apparatus. Overall, Dendronotus serves as a well-documented example of nudibranch diversity and taxonomy.
