Snakes are from 6 inches long to 30 feet long.
They have long, thin bodies. Their
bodies are covered by a tough bunch of plates and scales that is nearly
water tight. Snakes' eyes are
covered by clear scales that keep the dirt out.
Snakes are many different colors which helps them to blend in with
the land around them.
These animals hunt for food and eat small animals.
There is a small hole between the snake's upper and lower jaws. This
lets the snake's tongue go in and out without it opening its mouth.
Some snakes lay eggs and the eggs stay inside their bodies.
and estivate to get away from
the cold or heat. When their
nights are cool, they will go out in the daytime, and lay on a rock in the
sun until they warm up. In some climates,
the cold will kill them so they hibernate. The desert snakes have a
different problem and need to get away from heat and dryness.
Snakes are cold-blooded and their
body temperatures are about the same as the air temperature around
them. They would freeze or cook if the temperatures were too low or
too high. They adapt to the environment
around them by sleeping through the bad times.
Snakes look for caves, holes in the ground, or
cracks in rocks to sleep in. A
layer of dirt on top of their den helps keep them warmer or cooler.
Dens sometimes have hundreds of hibernating snakes in them.
When hibernating, the snake’s heartbeat slows and it needs less
oxygen and energy. Its body
temperature falls and breathing slows down.
Snakes eat more food before they hibernate so that they can live on
