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…

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

A small, active flatworm spotted in the shallows.

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

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

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