Crypsis in early benthic phases of Brachyuran Decapod Crustaceans in central Chile

Aunque comunes, y en algunos casos de valor comercial, poco es lo que se conoce acerca de los mecanismos y procesos que afectan la distribucion y abundancia de muchas especies de crustaceos decapodos, particularmente en Chile. Todas estas especies poseen larvas planctonicas que deben asentarse y reclutar antes de pasar a formar parte de los segmentos adultos de sus poblaciones. En varias de estas especies hemos detectado la presencia de una variedad de morfos de coloracion en individuos recien asentados. La existencia de dichos morfos en especies chilenas es comparable con aquellos observados en otras latitudes (e.g., costa del Golfo de Maine). Por otro lado, es caracteristica la aparicion de estos patrones solo durante los estadios juveniles tempranos y, al alcanzar cierto tamano, estos desaparecen, siendo los adultos tipicamente monocromaticos. La expresion de este patron en el submareal chileno parece ser mas pronunciada en las especies detritivoras que en las carnivoras. Proponemos que la existencia de este tipo de atributos fenotipicos, aparentemente generalizado en decapodos braquiuros, podria jugar un rol importante, tanto desde un punto de vista ecologico como evolutivo
