Dear Paulo and John,
It is a chrysopetalid. The paler tube is part of the enteron not the pharynx. Please not the continuous series of dorsal paleae and their orientation is usually towards the posterior region, such that the anterior region should be on the opposite side of the exposed enteric tube.
No idea about the genus. There are several other colleagues with a better idea.
Have fun,
Sergio

>> My guess is a polychaete in the family Flabelligeridae. It is segemented, looks like it has chaetae and cirri, and the two clusters of long shiny bristles at the anterior end suggest Flabelligeridae.

>> Hi all!
>> thank you for your comments! I should write what I think in the last mail.
>> So... when you look dorsally you can see "chaetae" arrangement looking like chrysopetalids but ventrally you fins this kind of legs.
>> I have worked with polychaetas for a longtime but I dont think it is a polychaeta because the "chaeta" does not have the same kind of insertion than polychaeta. In polychaetes the chaeta come from internal body and in this animal, it is a kind of just attached in body surface. Moreover this animal has 13 pairs of "legs" with spines attached and this kind of insertion reminders me crustaceans. The legs appear to be articulated and the body surface is covered by minuscules spines.
>> attached in this mail, you can find a picture of the rigid "chaeta" from this animal maybe calcareous????
>> I hope someone knows what this can be :D
>> Best regards,
