ABSTRACT
As part of a larger comparative study, marine polychaete hard-bottom assemblages were surveyed using artificial substrate units (ASUs) deployed at four sites off the islands of Trinidad and Tobago. The polychaete fauna was represented by 19 families comprising 89 species. The syllid Exogone dispar was the most abundant polychaete followed closely by the serpulid Pseudovermilia occidentalis. At the family level, the polychaete fauna inhabiting the ASUs is similar to the fauna from other temperate and tropical locations. Omnivorous species were dominant (70 %), followed by filter feeders (20%). This survey provides first records of the hard-bottom polychaete fauna of Trinidad and Tobago and adds new information about the geographic range of some polychaete species. Rev. Biol.

RESUMEN
Como parte de un estudio comparativo más amplio, ensamblajes marinos de poliquetos de fondos duros fueron contabilizados utilizando unidades de sustrato artificial ubicadas en cuatro sitios de las islas de Trinidad y Tobago. La fauna de poliquetos estuvo representada por 19 familias, integradas por 89 especies. Exogone dispar fue el poliqueto más abundante seguido cercanamente por Pseudovermilia occidentalis. A nivel de familia, la fauna de poliquetos que habitan las unidades de sustrato artificial es similar a la de otras localidades templadas y tropicales. Las omnívoras fueron las especies dominantes (70%), seguido por las filtradoras (20%). Este estudio proporciona los primeros registros de la fauna de poliquetos del fondo duro de Trinidad y Tobago, y añade nueva información sobre la distribución geográfica de algunas especies de poliquetos.
