Pirate perch

The pirate perch (Aphredoderus sayanus) is a freshwater fish that commonly inhabits coastal waters along the east coast of the United States and the backwater areas of the Mississippi Valley. This species is often found towards the bottom of clear, warm water habitats with low currents. These fish are normally solitary, carnivorous, and nocturnal. The pirate perch is known to consume live mosquito larva, amphipods, glass shrimp, meal worms, small fish, dragonfly and stonefly larvae, and earthworms.

The pirate perch is related to the trout-perches, but only loosely; it is the only species in its family, Aphredoderidae. The specific name sayanus is a tribute to naturalist Thomas Say. Charles C. Abbott gave the fish its common name after observing it eating only other fishes.
