Due to to diversity of polychaetes it is obious that you have to use several papers to find the feeding guilds of species. I have attached two important papers for the beginning.

Cheers Michael

Dear Jayachandran,

If you asked about trophic guilds of freshwater benthic animals I would refer you to the MaTroS program (macrozoobenthos trophic structure). In your case, as I see,you need info about sea invertebrates. Unfortunately I can't help in this situation :((

ITS OK TIMUR

Dear Jayachandran,

I agree with our colleague Michael L. Zettler. Indeed, feeding depends on the species kind which is mainly related to the ecological conditions in the studied ecosystem. You can see some elementary data on Nereis diversicolor in our paper on research gate.

Dear Mohamed Cheggour, kindly sent link of that paper

Dear Jayachandran ,

The above link might help for polychaetes.

The following link might help you get on the way. Next to the genus traits, it features a list of relevant publication with (almost) all species groups.
