Frogs have many adaptations that allow them to live on land and water. These include lungs, porous and regenerating skin, superior vision, webbed feet and mucus excretion.Know More
Frogs may breathe through their skin or using their lungs. Oxygen from air or water is dissolved into the frog's thin skin and diffused through the walls of the blood capillaries into the blood stream. When on land, frogs are able to breathe through their lungs simultaneously with their skin. The lungs are a much more efficient way for frogs to acquire oxygen. Frogs do not have to breathe rhythmically as most animals do, instead taking in oxygen only as needed. Frogs have nasal valves to prevent the intake of water into lungs when swimming.
A frog's skin is covered with a protective mucus to keep it from drying out. Frogs replace their skin weekly by pulling off old skin to reveal new skin underneath.This regeneration process ensures that the skin stays soft and efficiently coated with the protective mucus.
Frogs have webbed feet that allow them to move through the water more efficiently. Their strong hind legs help them to swim and leap more efficiently. They have excellent vision to allow them to see in poor conditions, such as murky water and nighttime.Learn more in Frogs
Poison dart frogs live naturally in the rainforests of Central and South America and on some of the Hawaiian islands. The frogs are also bred to live in many zoos around the world.Full Answer >
One of the adaptations that allow frogs to live on land and in water is their permeable skin, which allows them to absorb water from their surroundings. However, if the frogs are trapped away from water for a significant length of time, this may cause them to desiccate. To help prevent this from happening, frogs produce a mucus coat, which retards the rate of evaporation.Full Answer >
Red-eyed tree frogs live as far north as southern Veracruz and northern Oaxaca in Mexico, throughout the Central American countries of Guatemala, Belize, Honduras, Nicaragua, Costa Rica and Panama, and as far south as the Caribbean coast of northern Columbia. They inhabit tropical forests near freshwater ponds, rivers and other bodies of water from sea level up to almost 4,000 feet.Full Answer >
