The Vermiculated Fishing Owl is a large owl that hunts fish, crabs, and frogs along rivers at night. Its brown back is finely vermiculated, and its pale belly is streaked.
The brown upperparts have fine vermiculations, while the pale to sandy underparts carry dark streaks. It lacks ear tufts.
It hunts at night from a branch over a river, taking fish near the surface. It also eats crabs and frogs, and occasionally small birds or mammals.
