Interesting picture Arturo. I think this is a larva from a Polychaeta.

Arturo,

Franz is of course correct. I think it would be difficult to identify the genus as it is an early "nectochaete" stage. It still retains a ring of cilia behind the head which represents the ring of cilia found on the earlier "trochophore" stage. As the larva develops, these cilia will disappear, more segments will be added and it will take on more mature appearance which would make it easier to identify.

You might find this illustrated key useful:

...it is for the northern Pacific, but the families and genera of polychaetes are widespread.

a nice picture of a stage not often photographed- thank you !

boa sorte

Arturo,

Very nice!

The background and contrast on this one is very good, I like this DIC setting.
