          Abstract

          Durante junio de 1988 a julio de 1992 se realizaron muestreos no continuos en el Parque Nacional Natural Gorgona donde se colectó información sobre el contenido estomacal de dos especies de peces cartilaginosos de la familia Triakidae. Del total de muestras obtenidas 139 correspondieron a contenido estomacal de Mustelus lunulatus y 51 a M. henlei. En general estas especies depredan sobre crustáceos (93,06%) principalmente Portunus iridiscens, Squilla panamensis e Hipoconcha panamensis, en segundo lugar se encuentran los moluscos de la familia Loliginidae (4,32%) y en menor proporción peces (2,28%); el restante 0,34% corresponde a material digerido. En el contenido estomacal de estos organismos se encontraron nemátodos e isópodos los cuales no se tuvieron en cuenta en el análisis, pues se los consideró como accidentales.

          Translated abstract

          From June 1988 to July 1992, non-continuous samples of two species of cartilaginous fish of the family Triakidae were taken in the National Natural Park Gorgona. Stomach contents of 139 individuals of Mustelus lunulatus and 51 individuals of M. henlei were analyzed. These species predate on crustaceans (93,06%), mainly Portunus iridiscens, Squilla panamensis and Hipoconcha panamensis, secondly on mollusks of the family Loliginidae (4,32%) and fishes (2,28%) in a smaller proportion; the remaining 0,34% corresponded to digested material. Nematodes and isopods were found in the stomach contents of these fishes, but we considered them as accidentals and were not included in the analysis.

              CRUSTACEOS DECAPODOS DEL PACÍFICO COLOMBIANO: LISTA DE ESPECIES Y CONSIDERACIONES ZOOGEOGRAFICAS

              The Pacific coast of Colombia has been poorly explored, and its fauna is one of the least known in the tropical eastern Pacific. Although knowledge of the decapod fauna from this coast has recently increased, the information is scattered in numerous sources. A review of the literature showed that 378 decapods have been reported from this coast, including the islands of Gorgona and Malpelo. The numbers of species are distributed as follows: Dendrobranchiata, 18; Caridea,79; Thalassinidea, 13; Palinura, 6; Anomura, 61 ; and Brachyura, 201. Twenty-seven species are known exclusively from the Colombian coast, three of which are endemic to the islands of Malpelo or Gorgona. A list of nominal species is presented, including information on distribution, important references, and synonyms under which the taxa have been reported for this coast. A summary of the history of explorations of the Pacific coast of Colombia as it relates to decapods, is presented. Zoogeographie affinities are briefly discussed for the marine species based on published distributions. Affinities are greatest with the Gulf of California (51.8%), followed by the Galapagos (28.6%), the Indo-Pacific (8.8%), and the Caribbean- Atlantic (7.7%).
