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.Continue Reading
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.Learn more about Frogs
A tadpole can be identified by the length of the body, the length and shape of the dorsal tail fin and the ventral tail fin, the tail musculature, and the placement of the eyes and nostrils. The tadpole's habitat and the time of year it's found are also clues. Still, identifying tadpoles remains difficult because tadpoles are small and are in a constant state of metamorphosis.Full Answer >
Frog droppings are about an inch longÂ and roughly the size of a U.S. quarter. It is common for the scat to contain the exoskeletons of insects recently consumed by the frog.Full Answer >
A frog breathes through its skin, the inner surface of its mouth and its lungs, depending on its circumstances. When their skin is moist, and particularly when they are in water where it is their only form of gas exchange, they breathe through their skin. When it is necessary, such as on land, they take air into their lungs by pushing it from their mouths with their nostrils closed.Full Answer >
Even when they sleep, frogs do not close their eyes. Frogs do, however, have eyelids that blink to protect their eyes from dirty residue and preserve moisture. Frogs also have a third eyelid, called the nictitating eyelid, that facilitates a clear view when swimming underwater or on land.Full Answer >
