Description
A medium-sized pleurobranch reaching about 70 mm in length, ovate and convex; the mantle is distinctly notched anteriorly and the foot extends well behind it. The cephalic shield is slightly bilobed, the eyes more visible than in larger congeners. Body covered in close-set, low, rounded tubercles, each in life surrounded by a dark-purple ring with a central dot on a brilliant red ground. The sides of the foot are also speckled in this colour. The bright red pigment fades on washing or handling, exposing a yellowish ground colour. The thin, delicate dorsal shell sits in the centre of the back over the gill. Gill openings remain hidden in the groove between the foot and mantle. Common on reefs in the harbour of Port Louis, Mauritius.Distribution
Indian Ocean and adjoining western Pacific. The type locality is Mauritius, in the harbour of Port Louis (based on Péron material).Etymology
The specific epithet peronii honours François Péron (1775–1810), the French naturalist who collected the original material that Cuvier examined for his establishment of the genus Pleurobranchus.Remarks
Type species of the genus Pleurobranchus. Nocturnal, hiding under rocks during the day.References
