Poliquetos (Annelida: Polychaeta) epibiontes de Spondylus americanus (Bivalvia: Spondylidae) en el Parque Nacional Mochima, Venezuela / Polychaetes (Annelida: Polychaeta) epibiont on Spondylus americanus (Bivalvia: Spondylidae) from Mochima National Park, Venezuela

ABSTRACT

The polychaetes epibiontic on the mollusk Spondylus americanus Hermann, 1781 were extracted from mollusks hand-collected at a depth of 10-30 m in Mochima National Park, Venezuela (10 degrees 21'00[quot ] N-63 degrees 23'36[quot ] W), using scuba diving gear. Forty-three polychaete species were identified on the 32 bivalve specimens analyzed. The Serpulidae included 17 especies, Eunicidae six and Terebellidae four species. The most abundant species were Hydroides dirampha Mõrch, 1863, Pileolaria militaris Claparède, 1868 (Serpulidae), and Notaulax nudicollis Kroyer, 1856 (Sabellidae). Their geographic affinitie were 51.3% Atlantic, 28.2% widely distributed, 17.9% Amphiamericans, and 2.6% have a disjunct distribution.

RESUMEN

Se recolectaron poliquetos epibiontes de ostiones (Spondylus americanus Hermann, 1781) recolectados entre 10 y 30 m de profundidad en el Parque Nacional Mochima, Venezuela, empleando equipo de buceo autónomo. Se analizaron 32 ostiones, identificándose 43 especies de poliquetos; 51.3% del Atlántico, 28.2% cosmopolitas, 17.9% anfiamericanas y 2.6% “disyuntas”.
