Weird sea slug or nudi in Roatan, Honduras

[Ocean Connections]

Hey guys, a friend of mine spotted this creature, we have been seeing it regularily for the last 6 -8 months and it hasn't changed in size or distribution. We end to find it near clumps of red algae, either on coral or in rubble zones.
It is less than 1/4 inch long and has no visible gills or rhinophores.
Check out the picture.

It's a small flaworm. I photographed something similar in the BVI.

Does it have a name?

 

[LeslieH]

I haven't been able to find one. A lot of these small critters are undescribed or else the living appearance is unknown so there's no way to match a description to a photograph.

How do you know its a flatworm?
(not that I don't believe you just wondering the reasons)

 

[LeslieH]

I didn't at first. Another expedition team member did. Later I started looking into the smaller groups of flatworms like the acoels. This shape - like an elongated loaf of french bread, like a hybrid between a nemertean & a flatworm - is one of the typical forms. The color pattern seems to be as well.

Anywhere on the net i can get more info about these acoels?

 

[LeslieH]

Sure - here at
Acoela: Definition and Much More from Answers.com and from the research lab of Matthew Hooge who specializes in them:
