How can amphibians live on land

They slow their metabolism and their heartbeats down and survive off stored body reserves throughout the winter. There are some frog species that can even survive freezing temperatures by maintaining a high level of glucose in their blood that acts like antifreeze. Some of the frog will actually freeze, like their bladder, but their blood and vital organs do not freeze. The heart can stop beating and the frog can stop breathing, but it when it thaws out, it will still be alive.

No, only some species of amphibians are poisonous. Usually they are brightly colored to warn predators of their toxic nature. Most amphibians secrete chemicals from their skin to make them taste icky to predators or make it difficult to handle them. These secretions can be slippery or can be sticky and irritating to the skin. Do you know where rattlesnakes live in our state?

How do amphibians breathe? People brought them. Ironically, they were never used for either and instead have taken over many low elevation areas in Washington state. They breed fast each female can lay 20, eggs per clutch and can breed multiple times in a year. Their tadpoles are distasteful, giving them a high rate of survival. They are fierce competitors with voracious appetites often times will wipe out native amphibian populations.

Amphibians are found in almost all types of environments including deserts. Because amphibians generally have moist permeable skin, it is sometimes strange to think that they could do well in hot, dry conditions.

However, amphibians are very versatile and have established many adaptations to survive in such environments. Some desert toads bury themselves underground and only come out every few years when a good rain comes down to breed in temporary pools.

Other frogs or toads secrete wax that they coat their skin with to protect themselves from drying out.

Others are active only at night when temperatures are cool. Yes, the crab-eating frog can survive in brackish water because they can hold their urine in their body to help maintain proper internal salt balance. The crab-eating frog develops in freshwater but hunts for food in mangroves, marshes and coastal scrubs throughout SE Asia.

As the tadpoles grow, they develop legs and lungs that allow them to live on land. This big change is called "metamorphosis.

All amphibians are predators on other animals and will often eat any animal that is small enough to be swallowed whole. Most can only eat invertebrates, but some larger amphibians will eat small fish, other amphibians, or even small mammals. All amphibians are cold-blooded, like fish, snakes, lizards, and turtles.
