Los espiónidos (Polychaeta: Spionidae) del Golfo de California y Golfo de Tehuantepec, México

Abstract

La composición y distribución de los espiónidos, una de las familias de poliquetos más diversas, abundantes y frecuentes en la plataforma continental del Pacífico mexicano, se estudió en los golfos de California y Tehuantepec. Se consideraron 37 localidades de la primera región y 30 de la segunda. Se identificaron en total 5153 organismos de 12 géneros y 27 especies. Los espiónidos se distribuyen preferentemente en las costas de la porción centro-oriental del golfo de California, y al oeste de Salina Cruz, en el golfo de Tehuantepec, en profundidades entre 60 y 100 m. La especie dominante en ambas áreas fue Parapriospio pinnata, una especie cosmopolita que está prácticamente distribuída en toda el área de estudio y representa el 75% y 86% del total de organismos en el golfo de California y de Tehuantepec respectivamente. Los espiónidos, representados básicamente por especies anfiamericanas y de amplia distribución geográfica, agrupan al 64% de los organismos de ambos golfos

The composition and distribution of the Spionidae, one of the most diverse, abundant and frequent polychaete families in the continental shelf of the Mexican Pacific was studied in the Gulfs 01' California and Tehuantepec. Thirty seven stations were sampled in the former and 30 in the latter. A total of 5153 organisms in 12 genera and 27 species were determined. The spionids were better represented in the central-eastern region in the Gulf of California and to the west of Salina Cruz, in the Gulf of Tehuantepec, in depths ranging from 60 to 100 m. In both areas, the dominant species was Parapríonospio pinnata, a cosmopolitan species, distributed practically along the entire study area and representing 75% and 86% of the organisms found in the Gulfs of California and Tehuantepec respectively. The spionids, basically represented by species with Amphiamerican or extended geographic distribution, represent 64% of the organisms from both gulfs.
