Logperches are a unique subgroup of of a family of fish known as darters. They are easily distinguished from virtually all other darters by their tiger-like coloration, and distinctive head and snout shapes.
These fish have a unique foraging behavior: they flip stones on the stream bottom with their snouts to expose prey hidden underneath. Logperches eat aquatic insects, young crayfishes and aquatic roundworms.
The Darter Family has the second largest number of species of freshwater fishes in North America (only the minnow family has more species). Currently there are about 165 species of darters known and all reside in North America.
They are usually found in areas with considerable sand, gravel or rocky areas in lakes or medium to large streams and rivers. Logperches and are among the largest of darters in size, six inches in total length.
Darters usually rest on the bottom. When disturbed, they dart away quickly to a hiding place, which accounts for their common name.
