Fun facts about reptiles and amphibians

There are 8,240 species of reptiles in the world, inhabiting every continent except Antarctica

Hundreds of millions of years ago, amphibians became the first vertebrates to live on land

Reptiles and amphibians are cold-blooded, or "ectothermic," animals, which means that they depend on external sources, such as the sun, to maintain their body temperatures

Since they don't burn energy to heat internal "furnaces," reptiles eat 30 to 50 times less food than do birds and mammals (warm-blooded animals) of similar sizes

Some turtles and tortoises, including the Eastern box turtle, can live for more than a century

Only a few hundred of the world's 3,000 snakes are venomous

In the United States, only rattlesnakes, copperheads, cottonmouths, and coral snakes are poisonous

More Americans die each year from bee and wasp stings than from snake bites

One way to tell a frog and a toad apart: frogs have smooth, clammy skin, while toads have more dry, bumpy skin

Both frogs and toads lay their eggs in water, but toads spend more of their time on land than do frogs

Averaging ten to 12 feet in length, the king cobra is the largest venomous snake in the world

It is also the only known snake that builds a nest for egg incubation

Frogs can breathe not only with their lungs, but also through their skin

A frog's skin is thin and contains many mucous glands that keep it moist

Oxygen can be absorbed through this thin, damp skin

Depending upon the size of the meal, anacondas can go several months between meals

More than 75 percent of all toad and frog species in the world live in tropical rainforests

The emerald tree boa can strike a bird or small mammal in complete darkness

The pits along the lips of most boas and pythons, and the nostril-like cavities of pit vipers, are infrared heat receptors

Snakes use these pits to sense the location of anything that differs in temperature from its surroundings by as little as 0

4 degrees Fahrenheit
