The Sleeper

Like all native freshwater fish species in French Polynesia, the dusky sleeper (Eleotris fusca) moves between fresh- and saltwater at certain points of its life cycle. More specifically, this species is amphidromous, meaning it hatches in freshwater streams, migrates into saltwater, and later returns into freshwater. This enables it to colonize the freshwater streams of remote islands, where it preys on crustaceans and small fish.
