Please contact Dr. Murugaeshan at Marine Biological Station, Parangipettai for identification.

José Tena Medialdea

It's extremly difficult to identify Polychaetes from pictures. I can see some Syllidae, Capitellida, Orbinidae, fragments of several families, etc. . I recomend you to send samples to a local specialist. Dr. Murugaeshan could be a good option.

Michael Reuscher

Nr. 12 looks spionid like with its paired palps, Nr. 28 is a syllid.

For the other specimens you need to post pictures in higher resolution!

Prince Samuel Godson

Than you all for your concern....
