Diversity and distribution of the crustacean decapods of the upper continental slope (300-500m deep) in the nort colombian Caribeanean sea
Abstract
The Instituto de investigaciones Marinas y Costeras INVEMAR, developed the proyect about thecaracterization of the macrofauna of the upper continental slope of the Colombian Caribeansea. The present proyect covered the identification, distribution, abundance and faunisticalcomposition of the crustacean decapods, of the north of Colombian Caribean sea, between LaGuajira and Magdalena, to 300 and 500m deep. The material was placed in the Colección deReferencia de Organismos Marinos of INVEMAR and the Museo de Historia Natural delInstituto de Ciencias Naturales de la Universidad Nacional de Colombia. The taxonomicinformation about each species was fed the data base about marine biodiversity of theINVEMAR. 6381 individuals of the crustacean decapods were collected and 99 species, 48 ofwhom are the firts report for the species in the Colombian Caribean sea and, two are newspecies. One of the genus Cymonomoidesand the other of the genus Pyromaia. Five families werethe most abundant 77% two groups of the crustacean decapods there established. One to300m deep, caracterized for the species Portunus spinicarpus, Methanephrops binghami, Munidalongipesy Penaeopsis serrata. The secon group at 500m deep was caracterized by the speciesGlyphocrangon neglecta, Pleoticus robustusy Munidopsis riveroi.
