Giant Talking Catfish

The Giant Talking Catfish is a bottom-dwelling predator with a flat head and upward-facing eyes and mouth. It hides itself in sand or mud, blending right in, then snaps up any small fish or crustaceans that swim overhead. Depending on the species, they can grow anywhere from 20 to 50 cm, and their colors—gray, brown, or yellowish—help them disappear against the riverbed.
