Flatworm

Hi everybody!

Found this nice looking flatworm from Zanzibar. Anybody have any idea what flatworm this is?

I found it from around 10m. Size was 1"-2".

Very similar to Pseudoceros bifurcus

The lines on this one looks to be much wider, and the orange spot is quite big. I will post another picture later, which shows the flatworm closer.

Hi Heikki --

Jim may be right. Some species like Pseudoceros dimidiatus are quite variable in appearance. While P. bifurcus usually does have thin lines & a small narrow orange spot this color pattern shows up occasionally.

" thank you for your submission. Yes, it does have the indications of being the species you mention and although flatworms are subject to extraordinary colour variations I have stacks of P. bifurcus from all over but nothing with such definite black markings. I would reserve my judgment until I see more specimens.

FAMILY: PSEUDOCEROTIDAE

COMMON NAME: ZANZIBAR FLATWORM

SCIENTIFIC NAMES: Pseudoceros sp. "

That kind of answer I got back from Neville Coleman.

Here's the second picture

Very cool. I've seen images of 3 or 4 of these and never knew if they were just aberrant specimens or something new. Thanks for posting Neville's reply.
