What is difference between a turtle and a tortoise?

Turtles and tortoises are reptiles with shells on their backs. Most can pull their heads, legs, and tails inside the shell for protection.

Many turtles spend a lot of time in the water. They can swim much better than they can walk. The sea turtle spends almost all its time in the water and has strong flippers for swimming. These turtles eat animals and plants.

Tortoises are turtles that live only on land. They have club-like legs for walking on sand, mud, or grass. The shells of most tortoises are tall and round, while the shells of many other turtles are flat to help them glide through water. Most tortoises eat plants.

Turtles don’t watch over their eggs before they hatch. Female turtles dig holes in the mud or sand. They lay their eggs in the holes, then cover up the eggs and go away. The warm sun hatches the eggs, and the babies dig their own way out.

How can a lizard survive in the desert?

It’s the middle of the night in the desert. A small lizard lies almost covered with sand. Only its head sticks out. It is using the sand like a blanket to keep its body warm during the cool night.

When the sun comes up, the lizard crawls out of the sand. It moves very slowly because it is still cold. It lies on a rock for a long time, letting the sun warm it. When its body is warm enough, the lizard dashes off to look for food.

Lizards and all other reptiles are cold-blooded. Their bodies get just as hot or cold as the air or water around them. If their bodies get cold, reptiles can’t move well. If they get too hot, reptiles die. So reptiles must spend their time playing hide-and-seek with the sun. If they are cold, they lie in warm sunshine. If they are hot, they hurry into the shade.

A reptile that lives where winters are cold moves more and more slowly as cold weather comes. The reptile curls up in the warmest hole it can find. Soon its body grows cold and stiff. It cannot move at all. Only when warm weather returns can the reptile move again.

What are reptiles and amphibians?

Have you ever seen a big, fat frog? Did its bulging eyes and raspy croak make you laugh?

Have you ever seen a tiny garden snake zipping through the grass? Were you amazed at how fast it could travel with no feet?

Snakes and frogs belong to two groups of animals called reptiles and amphibians.

Amphibians and reptiles slither, scamper, hop, or swim. Some hiss, some croak, and some make no sound at all. Some amphibians have scaly skin that feels like tree bark. Some snakes have skin that feels like warm glass. Some frogs are slimy, but most snakes are not.

Amphibians and reptiles live all over the world – in woodland forests and rain forests, the Australian outback and the African plains, and maybe in your own garden.

What is a Reptile?

Suppose you found some eggs lying on the ground. Now suppose that some little creatures with scales hatched out of them. What kind of animal would they be?

Could they be fish? Fish have scaly skin, but fish eggs do not have hard shells. Besides, most fish lay their eggs in water. So they could not be fish.

Could they be birds? Birds lay eggs, too. But birds don’t have such scaly skin. So they could not be birds.

They must be reptiles. Only reptiles have scaly skin and lay their eggs on land. Alligators, crocodiles, lizards, snakes, turtles, and tuataras are all reptiles.

How do webbed feet help birds move in water?

Did you ever swim wearing flippers? If so, you know that they help you swim faster. Flippers are like the webbed feet of ducks, geese, and swans. Webbed feet are like paddles. They push lots of water, so the bird can move faster.

Ducks, geese, and swans are all waterfowl. They spend most of their time in lakes, ponds, rivers, or the sea.

Different kinds of waterfowl have different ways of getting their food. Some kinds of ducks, such as mallards, wigeons, and teals, are known as dabbling ducks. To get food – water insects, snails, and water plants – a dabbling duck puts its head underwater. Its feet and tail stick straight up in the air. Swans feed this way too, but they eat mostly plants.

Ducks such as pochards, canvasbacks, and grebes are known as diving ducks. They dive underwater and eat mostly water plants.

Geese usually feed on land. They like grass, seeds, and plants. Their bills can clip off the tops of plants as neatly as a pair of scissors.

Colourful mandarin ducks often perch in trees when they aren’t swimming.

What is significance of Bird Feathers?

You know that all birds have feathers. Some feathers are quite beautiful. But what are feathers for? Feathers help most birds to fly, but they are important for other reasons, too.

In cold weather, a bird’s feathers make a warm winter coat. The bird fluffs up its feathers to keep its body warm. For some birds, waterproof feathers act like a raincoat. These birds can swim and dive without getting too wet and sinking.

The colours of feathers can be important, too. Bright colours help some birds attract mates. Other colours make birds blend in with their habitat so they are hard to see. Then hungry enemies won’t notice them.

All birds have wings. Wings are for flying, of course, and most birds can fly.

A bird’s wings are thin and very light. They are nothing but a few little bones and small muscles covered with thin skin and feathers.

Bird wings aren’t all the same, however. The kind of wings a bird has depends mainly on the bird’s way of life.
