This pleurobranch is similar in shape and colour to the Mediterranean species Pleurobranchus testudinarius (Cantraine, 1841). It is large and tuberculate, often with bright pink or yellow rings encircling the base of each tubercule. It has seldom been reported since Quoy & Gaimard's first report from Mauritius. It has been found in New Caledonia (personal observations), New South Wales, Australia (Allan, 1957), [and possibly from the Great Barrier Reef (Kenny, 1970) and southern Africa (MacNae, 1962)]. It has also been recorded from Kerama Islands, southern Japan as P. grandis by Atsushi Ono (1999).
