Agu -- capitellids & cirratulids (the hair worms) are so well known for their ability to population low oxygen & pollution areas that they are considered prime pollution indicator species. A bottom sample from a clean area will have many different species. A sample from an outfall or impacted area will have only a few species but these will occur by the thousands or tens of thousands, and caps & cirris will be the most abundant. Many labs keep capitellids on hand for toxicity studies so there should be a lot of information available on how to culture them.
