Red-finger aeolis

The original description of this species is of an animal with unusually short, rounded cerata, hence the name verrucosa. The name has been extensively used for animals of different appearance, with long cerata, including Coryphella rufibranchialis, the type species of the genus Coryphella. The body of Coryphella verrucosa is translucent white. The tail is elongated and pointed with a mid-dorsal line of opaque white pigment in which there are round translucent spots. This white line may extend along the back amongst the cerata from the tail, breaking up into spots. In different parts of its range this species has differently coloured forms, which may be different species. In some places the digestive gland in the cerata is red while in other locations, cerata with brown digestive gland predominate, though it is known that the colour of the digestive gland in species of Coryphellidae is dependent on diet. There is also considerable variation in the colouring of the tips of the cerata, from narrow broken rings (F. rufibranchialis form) through broad white bands to white almost covering the tips of the cerata in the typical form. The oral tentacles have a broad white stripe on the upper surfaces. The maximum recorded body length is 35 mm or up to 40 mm (1.6 in). This nudibranch is similar in appearance to Microchlamylla gracilis and many other species of Flabellinidae.
