Dendronotus is a genus of sea slugs, nudibranchs, marine gastropod molluscs in the superfamily Tritonioidea.[1]

This genus is within the clade Cladobranchia (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).

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. These extensions may be branched. Smaller unbranched extensions are found around the mouth. The rhinophores are surrounded by a sheath and the sheath itself has branched extensions. 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.[2]

This genus feeds on hydroids, as reflected by its serrated radula.[4] [5][6]
