Description
In life the ground colour is milky white, the back speckled vermilion, and the cerata blackish-brown. The body is slender, elongate and somewhat compressed. Rhinophores recall those of Berghia, with the club covered by ranks of small knobs. The oral tentacles are stout and elongate. The cerata are elongate cylindro-conical, not readily caducous, and arranged in oblique rows that on the front half of the back gather into groups. The foot corners are strongly tentacle-like and elongate; the tail is not long. Preserved body length 24 mm.Distribution
Type locality: Insel Edam (= Pulau Damar, off Java, Indonesia). Subsequently recorded widely from coral-reef habitats across the Indo-West Pacific.Etymology
The specific epithet brockii honours the German zoologist Johannes Brock (1858-1908), who collected the single type specimen at Insel Edam. Brock, sent from the University of Berlin, collected sea slugs and many other marine invertebrates in Indonesia in the mid-1880s and supplied his material for description.Remarks
Described as the type species of the new genus Moridilla. A member of the Aeolidiidae, this species is a carnivorous predator of cnidarians, primarily anemones.References
