About Cratena capensis Barnard, 1927
Cratena capensis reaches a total length of 10 to 30 mm. This is a slender nudibranch with a pale body, smooth white rhinophores, and a pair of elongated oral tentacles. Two orange or red 'eye' patches are present on its head. Its cerata are reddish or orange with white tips, and the color of the cerata changes based on the nudibranch's diet. This species has only been found along the South African coast, ranging from Saldanha Bay to Port Alfred. It occurs from the intertidal zone down to at least 30 m depth, and is endemic to South Africa. Ecologically, this nudibranch feeds on a wide variety of hydroids. It produces an egg mass that forms a broad coil made of one or two whorls.
