Osborn et al., 2009
Swima is a genus of polychaete worm that lives in the deep ocean. This deep ocean pelagic (free-swimming) annelid has modified bioluminescent gills that can be cast off from an individual. These discarded gills somewhat resemble green "bombs" that remain illuminated for several seconds after they have been discarded. It is thought that this is a defensive mechanism rather than reproductive, as it is seen in both mature and juvenile individuals. Animals of the Swima genus are closely related to the recently discovered Teuthidodrilus genus, another pelagic cirratuliform of the bathyal zone.

Anatomy and physiology
Animals of the Swima genus are characterized by a thick gelatinous sheath, transparent body, simple nuchal organs, a single medial subulate branchia, and four pair of small segmental branchiae modified as elliptical, bioluminescent sacs.
