CONSIDERACIONES ZOOGEOGRAFIAS SOBRE LOS TIBURONES DEL PACIFICO COLOMBIANO

Abstract

The zoogeographical origin is determined and analized, and the distributional patterns in the eastern tropical Paciic are recognized for 22 shark species (Pleurotremata) recorded from the Colombian Pacific, including Triaenodon obesus, Ginglymostoma cirratum and Rhiniodon typus, recorded for the first time. The distributional patterns are discussed as a response to the historical and ecological factors which affect the species according to their zoogeographical origin; finally, a biogeographical characterization of the Gorgona Island is made based on the species that inhabit its surrounding waters.
