Introdução de espécies de Serpulidae RAFINESQUE, 1815 (Annelida): estudo de caso na Baía de Sepetiba, RJ

Abstract

Serpulidae is a globally distributed family of filter feeding, tubiculous, and fouling polychaetes. They usually are composed of an operculum, a radiolar crown, thorax, and abdomen. These animals are commonly translocated through vessels or floating debris. They can be found in port regions, as well as in places with a diversity of natural (e.g. rocks, mollusc shells) and artificial (e.g. pier, ship's hulls) substrates available for settlement. The knowledge about the species of serpulids within Sepetiba Bay is still scarce, aiming to expand this knowledge active collections were made in 15 places within the bay. Seven species belonging to four genera were identified, one being native and the other six exotic. With this survey it was possible to report three new records for Sepetiba Bay (Salmacina ceciliae, Hydroides dianthus and Protula balboensis) and to confirm the presence of Spirobranchus tetraceros for the state of Rio de Janeiro. We update the list of serpulid species occurring on the Brazilian coast even as the list of exotic species of polychaete present on Brazil. Nevertheless, we recommend increasing the efforts in evaluating the invasive potential and monitoring the Brazilian marine environment, mainly in port regions
