| Se reportan tres especies de picnogónidos para la región sudoeste de Santa Marta en el Caribe colombiano. Nymphon surinamense, Anoplodactylus insignis y Pallenopsis schmitti fueron colectados en arrastres sobre fondos blandos entre 14 y 60 m de profundidad. Este reporte amplía la distribución geográfica de N. surinamense y A. insignis en el Caribe y resalta la abundancia de P. schmitti en el área. La distribución y la sistemática de las especies se discute brevemente y se presentan ilustraciones para cada una de ellas. |

| Soft bottom megabenthic communities have been poorly studied in the Caribbean Sea. In this study we describe the structure and species composition of a Crustacea-Mollusca megafaunal community based on beam trawl samples taken between 13 and 60 m depth at the southwestern region of Santa Marta, Colombian Caribbean. Classification and ordination analyses using abundance data of crustaceans and molluscs produced two main groups (A and C), which seem to be controlled by depth and sediment characteristics. Group A consisted of species collected at the deeper stations and high content of silts (between 30 and 60 m depth) and exhibited the highest density and biomass mean values. The decapod Chasmocarcinus cilindricus was found as the characteristic species for... |
