Largest member of the Ranidae family, it may reach 8 inches in length. Predominately found in ponds or marshes (free of fish), also in lakes or rivers. Due to its large size, a Bullfrog can jump three to six feet in a single leap, and has a diverse diet. Primarily feeding on insects and crayfish, it may be observed eating snakes, small mammals, birds, and other frogs. Tadpoles hatch from eggs in four to five days, with their metamorphosis lasting as long as three years. Bullfrogs tend to live six to seven years; longest recorded lifespan is sixteen years.
Dark color, usually green, with four lighter dorsal stripes. Lacks dorso-lateral ridges found in other species. Ranges from 1.6 to 2.6 inches long. Primarily found in bogs and wetlands.
Typically green with brown patches or spots, males may have yellow throats. Dorso-lateral ridge extends only to mid-back. 2 to 3.5 inches in length. Green Frogs prefer ponds or marshes (free of fish), but also appear in any area with suitable moisture and food, including ditches and streams. Tadpoles usually mature in a year.
Ranging from olive green to brown, with distinct yellow pigment on lower legs. Other distinct features include a dark triangular pattern on head, and two intersecting dorsal stripes.
