A extreme eye closeup of a very large Ghariel. Gharials inhabit four river systems of the northern Indian subcontinent. Easily recognizable because of their unique appearance, both male and female gharials have long slender snouts and webbed hind feet. Gharials are among the largest living crocodilians. A mature male can grow to more than 20 feet in length, and a female can grow up to 13 feet in length.
