Genus Pseudoceros

The genus Pseudoceros contains the largest number of marine flatworms in our guide. Hence you are most likely to see them when SCUBA diving or snorkelling around Koh Phangan…

Similar in appearance to P. scintillatus, this a recognised species of mimic flatworm.

And what a scintillating flatworm it is! Not to be confused with P. zebra.

This flatworm was wrongly labelled before as Pseudoceros hancockanus - they all look so similar at first!

A small, active flatworm spotted in the shallows.

The elegant striped flatworm, not to be confused with P. monostichos.
