Potato Flatworm

Size about 50mm. For this species, I found a perfect match on quite a reliable website http://www.philippine-sea-slugs.com/Look-alike/Platyhelminthes/Paraplanocera_oligoglena/Paraplanocera_oligoglena_01.htm). I named the flatworm based on its shape less on its texture and other characteristics. The animal has nuchal tentacles, white specs all over its body, mixed with tiny red dots. It matches the Stylochidae shape better, but I am not going to argue with anyone on flatworm identification. Stylochidae are voracious predators of commercial bivalves. Well, that explains why most information on flatworms are withheld from the public.
