Being cold-blooded means that their bodies react to the temperature of their surroundings. When they get too warm, they can go into the water or shade to cool off. When they get too cold they can hang out in the sun to warm themselves up.
Some creatures that belong to the reptile group of animals are snakes, alligators, crocodiles, tortoises, lizards, etc.
Scales protect their bodies they can be hard or soft, large or small depending on the reptile speices.
Reptiles are born on land and are born with strong instincts, so they are on their own at birth. Just think, no parents to nag them about cleaning their rooms
What are snakes ?
Snakes belong to the animal class reptiles. This group also includes crocodiles, lizards, and turtles as mentioned above. As menitioned above aswell, reptiles are cold-blooded animals that raise their body temperature by lying in the sun or lower it by crawling into the shade. Their body temperature changes to the temperature of its surroundings. Because of this, snakes that live in colder climates must hibernate through the winter. They will find burrows or caves and fall into a deep sleep until the weather becomes ware enough for them.
There are more than 2,900 species of snakes in the world. They live almost everywhere, in deserts, forests, oceans, streams, and lakes. Snakes live on the ground, in trees, and in water.
Snakes cannot survive in places where the ground stays frozen year round so there are no snakes north of the Arctic Circle or in Antarctica. Some islands, including Ireland and New Zealand, do not have snakes at all.
What are Amphibians ?
The word amphibian means two-lives. Amphibians spend their lives in the water and on land. All amphibians begin their life in water with gills and tails. As they grow, they develop lungs and legs for their life on land. They are cold-blooded, which means that they are the same temperature as the air or water around them.
There are more than 4,000 different kinds of amphibians. Members of this animal class are frogs, toads, salamanders, newts, and caecilians or blindworms.
