What Are the Adaptations of a Frog?

Frog adaptations include specialized legs, feet, skin, eyes and body shape. Frogs primarily live in water, so many of their adaptations enhance their ability to live effectively in an aquatic environment.

Frogs have long and powerful legs that allow them to jump and swim for long distances. They also have webbed feet that act as fins to aid in swimming. The shape of the frog’s body is streamlined, with a slim body, no neck and a broad head, which allows it to propel itself through water more smoothly.

Frog skin is also adapted for aquatic life. The skin is thin and allows for cutaneous respiration, which means that a frog is able to absorb oxygen through its skin. The skin is also osmotic, allowing for the passage of water in and out. Because the skin is thin, it is also susceptible to becoming dried out. Therefore, frogs produce mucous that keeps the skin moist.

Frog eyes are large and round, sitting on top of the head. This positioning allows the frog to keep most of its body beneath the water while still maintaining a wide range of vision. The placement of the eyes also allows the frog to look around for predators and prey without moving its head. Frogs are able to see particularly well in dim conditions, including underwater.
