Brook trout

The brook trout , sometimes called the eastern brook trout, is a species of fish in the salmon family of order Salmoniformes. In many parts of its range, it is known as the speckled trout or squaretail. A potamodromous population in Lake Superior is known as coaster trout or, simply, as coasters. Though commonly called a trout, the brook trout is actually a char which in North America, includes the lake trout, bull trout, Dolly Varden and the arctic char. The brook trout is the state fish for eight states: Michigan, New Hampshire, New Jersey, New York, Pennsylvania, Vermont, Virginia and West Virginia

The specific epithet "''fontinalis''" comes from the Latin for "of or from a spring or fountain".
