Summary

[edit]
Description

Bispira brunnea (Treadwell, 1917) - social feather duster worms at a patch reef.

Social feather duster worms occur in clusters. Their bodies occupy irregularly cylindrical, parchment-like tubes composed of organic material and fine-grained sediments. Some feather duster worms have their tubes buried in the seafloor (infaunal). Social feather duster worms have their tubes exposed (epifaunal). The worms shown above have extended their crowns of feathery appendages, which extract dissolved oxygen and filter the water for particles of food (filter feeding/suspension feeding). When disturbed, the worms quickly retract their feeding appendages.

Classification: Animalia, Annelida, Polychaeta, Sedentaria, Sabellidae

Locality: patch reef just west of Cut Cay, eastern Graham’s Harbour, northeastern San Salvador Island, eastern Bahamas
