Se determina e interpreta el origen zoogeográfico y se reconocen los patrones de distribución en el Pacifico oriental de las 22 especies de tiburones (Pleurotremata) registradas hasta la fecha en el Pacífico colombiano, incluidas Tnaenodon obesus, Ginglymostoma cirratum y Rbiniodon typus, las cuales se registran por primera vez. Se discuten los patrones de distribución, como respuesta a factores historico-ecológicos; finalmente se hace una caracterización biogeográfica de la Isla Gorgona con base en las especies de tiburones presentes en sus aguas.The zoogeographical origin is determined and analized, and the distributional patterns in the eastern tropical Pacific are recognized for 22 shark species (Pleurotremata) recorded from the Colombian Pacific, mcluding Triaenodon obesus, Gmglymostoma cirratum and RhiniodoQ typus, recorded for the first time.
