a marine larva

[Franz Neidl]

This is a marine larva - "fished" today and unknown to me.
It is 280 µm long. Somebody can help me?

hi Franz,

it is a pilidium larva of a nemertine worm. The metamorphosis of this larva into an adult ribbon worm is extraordinarily complex.

Thanks for another fascinating group of photos (i think that these are rare on the web).
