Plakobranchus species; Plakobranchidae

This small Plakobranchus species Sacoglossan was spotted when we were diving on the sand at a local Koh Phangan dive site. It had a busy nature and long rolled rhinophores, which look quite like oral tentacles. This made us think that it was a species of Cerberilla until we saw the photos on the computer.
Apparently it belongs to the P. ocellata species complex although its behaviour and appearance might suggest otherwise.
