Bioluminescence in Pelagic Polychaetes
Journal of the Fisheries Research Board of Canada, 1971Of six holopelagic polychaete families, the Tomopteridae and Alciopidae are the only ones having representatives that appear to be photogenic. Previous investigators localized the site of photogenic organs to certain parapodial glands in the tomopterids. Photogenic organs have not been demonstrated in the alciopids, but some species have been reported

The Polychaeta or polychaetes are a class of annelid worms, generally marine. Each body segment has a pair of fleshy protrusions called parapodia that bear many bristles, called chaetae, which are made of chitin. Indeed, polychaetes are sometimes referred to as bristle worms. More than 10,000 species are described in this class.

During the 1990 Cordell Expedition to Rocas Alijos, numerous general collections of invertebrates in aggregate were made. While polychaetes were not deliberately targeted, large numbers of these worms were present in the collections. Several lots of aggregates were received by the author in 1990, from which five lots of polychaetes were separated ...
