New records of early life-stages of cephalopods in the Chiloé Interior Sea Nuevos registros de estadios de vida tempranos de cefalópodos en el mar interior de Chiloé

By Sergio A Carrasco, Roberto Maltrain, Francisco Villenas and Marco A Vega


Early life stages of cephalopods were sampled with zooplankton nets in southern Chile (41°-43°S) during the CIMAR 11 Fiordos cruise, November 2005. A total of 52 individuals were collected, comprising three families (Octopodidae, Sepiolidae, Onychoteuthidae) and four species (Robsonella fontaniana, Enteroctopus megalocyathus, Semirossia patagonica, an undetermined Onychoteuthidae species). Paralarvae of Octopodidae have been previously recorded in northern and southern Chile; however, for Sepiolidae and Onychoteuthidae, this is the first record of early life stages in Chilean waters.<br>Estadios tempranos de cefalópodos fueron obtenidos con redes de zooplancton en el sur de Chile (41°-43°S) durante el crucero CIMAR 11 Fiordos en noviembre de 2005. Un total de cincuenta y dos individuos fueron recolectados, comprendiendo tres familias (Octopodidae, Sepiolidae and Onychoteuthidae) y cuatro especies (Robsonella fontaniana, Enteroctopus megalocyathus, Semirossia patagonica, y una especie indeterminada de Onychoteuthidae). Si bien existen descripciones previas de paralarvas de Octopodidae para el norte y sur de Chile, este trabajo provee el primer registro de estadios tempranos de vida de Sepiolidae y Onychoteuthidae para aguas chilenas
