However, it can make … Read more

The wooly mammoth, which is an ancestor of our modern elephant, lived on earth for 3,000,000 years, and became extinct only 10,000 years ago. However, we know a great deal about these creatures, more probably than about any other creature that lived at the same time. Some of these mammoths made their home in the … Read more

Many small rodents live their entire lives without traveling more than 20 feet from their birthplaces. Yet there are some types of whales, humpback whales for example, who travel across the oceans of the world and cover more than 4,000 miles in one year! However, that record would not impress the Arctic terns, who are … Read more

It burrows tunnels in the ground, just like moles. And it nurses its young just like dogs, cats, and humans. What is this mixed-up creature? It’s the duckbill … Read more

Because we can easily see colors around us every day, we might assume that every creature does too. But that is not so. The question of whether animals can distinguish between colors has long, puzzled scientists. However, they have come up with some interesting answers as a result of thousands of experiments. Dogs, for example, … Read more

Worms can infest apples through a variety of means, but the most common way is by eating the moths that feed on young fruit.

However, if the infestation is extensive, it will probably take … Read more

What? The lowly earthworm, educated? Well, the answer is yes! This amazing feat was accomplished at the University of Michigan, where scientists used the common flatworm that you are likely to see in streams and ponds. These scientists taught the worms to crawl through a series of very difficult mazes, and the worms learned how … Read more

Creatures with backbones, like birds, fish, lions, and man, usually have a tail at the end of that backbone. Even man had a tail at one time. Tails are useful to many animals, but their use differs according to whose tail it is. Kangaroos and woodpeckers use their tails to prop themselves up and rest … Read more

No, but it often takes a very close look to see the difference, and who wants to get that close to either one of them! Alligators and crocodiles are both long, cigar-shaped reptiles, with four short legs, powerful tails, long snouts, and scales, or plates, covering their bodies. If you see a broad, rounded snout … Read more

One species of cicadas, small dark insects about 1 to 2 inches long with heavy bodies and thin wings, holds the insect record for the most unusual life cycle. The cicada, also called the 17 year-locust, spends 17 years sleeping in the ground, comes out for five weeks in the sun, then it dies! Scientists … Read more

For many years that question puzzled scientists, but in 1825 a scientist studied sponges under a microscope and saw water enter them through some openings and come out others, looking different. This was evidence that the sponge was an animal which captured tiny plants and animals from the water to use as food, digested them, … Read more

Really in many different ways, from many different places, and from many different languages! Ducks, for example, are birds who “duck” in the water. Their name comes from an old English word duce, which means a “diver.” The Arabic word zirafoh, which means “long neck,” gave the long-necked giraffe its name. Two Greek words, hippos, … Read more

The spotted hyena, which is the largest member of the hyena family, is appropriately named the laughing hyena. But don’t think that this creature laughs as you do, because of something funny or because it is tickled. The hyena’s laugh is more of a mixture of a weird howl and a chuckling gurgle. But these … Read more

The phoenix never existed. It was a large bird, much like an eagle, written about in Greek mythology and based on ancient Egyptian legends. Only one phoenix was said to have lived at a time.

The snail has an unusual body sticking out from the underside of its coiled shell. This body is actually a strong muscle called a foot.

Even though octopuses belong to a group of shellfish called mollusks, they have no outside shell. A tough skin, called a mantle, covers the octopus’ body. This mantle contains small bags of pigment, or coloring matter, which are connected to the animal’s nervous system. Any outside stimulus that excites the octopus makes its skin change … Read more

Although an octopus has eight arms, or tentacles, it does not use them for swimming. These tentacles are only for crawling along the ocean floor and for catching food. In order to move through the water, the octopus draws water into a cavity in its body, then squirts it out in jets through a tube, … Read more

Tiny, jellylike sea creatures, called polyps, have actually built reefs and entire islands. These cylinder-shaped, 1-inch wide polyps live in large colonies on the ocean floor and attach themselves to each other. Polyps remove a chemical called calcium from the sea water and use it to build a shell, or outer skeleton, of limestone around … Read more

Many large grazing animals, such as rhinoceroses and buffaloes, form strange partnerships with small birds. These birds, cattle egrets and tick birds are carried about on the backs of larger animals.

No. Cows do not start producing milk until after they have given birth to their calves. Until that time, they are called heifers. When heifers reach the age of 2-2.5 years, they are then mature enough to produce their young. A cow carries her unborn young for 283 days. This is called the gestation period. … Read more

Chewing a cud is a process by which some animals, called ruminants (camels, goats, sheep, deer, and cattle), thoroughly digest their food. The cow, for example, has a stomach organized into sections to take care of hard-to-digest food. When the cow first takes in food, it chews it just enough to moisten it. Once swallowed, … Read more

A snake’s tongue looks like a long, sharp, slender forked finger. People have long believed that when a snake flicks its tongue in and out of its mouth rapidly, it is preparing to attack.

Have you ever collected shells at the beach, especially the large, flat, rounded ones that many people use as ashtrays? Well, those shells once belonged to the sea creature known as the clam. At one time, two of those shells were fastened together and formed the home of the fleshy creature that lived inside. For … Read more

Clams, like oysters, have no eyes, ears, or noses, so they cannot see, hear, or smell. But they do have a large number of feelers, or tiny hairy projections on their gills. When the clam’s shell is open, these hairs fan the water, which is rich with small organisms, into the clam’s small mouth. From … Read more

Both clams and oysters are a class of mollusks, called bivalves. All bivalves have two shells held together by hinges.

The inside shells of oysters and other shell-forming mollusks are covered with a shiny, lustrous substance called nacre, or mother-of-pearl. Only tropical sea pearl oysters have the beautifully colored nacre necessary to make valuable pearls. Other edible clams and oysters also make pearls.

The salmon is this determined navigator. Not only will it travel great distances to reach the place where it was born, but it swims against strong currents while doing so.

The Australian walking fish is most unusual. In the water, it swims just like any other ordinary fish. But on land, this fish behaves as if it belongs there, for it actually walks! Its gills are bent in such a way that it can stroll out of the water and even climb up into the … Read more

Some fish, like guppies, give birth to live young, but most fish lay eggs. In spring and summer, when the water is warm enough for eggs to hatch, the male and female fish send signals to each other with their fins or their body. At this signal, the female lays her eggs in the water … Read more

The lamprey is a long, fishlike creature which resembles an eel. Lampreys differ from fish in that they have no limbs (fish have fins) and practically no scales.

However, it is these tentacles that make them so dangerous, for on them are stinging cells called nematocysts. When the umbrella-like jellyfish moves through the water, its tentacles drift along behind it. Jellyfish do not attack their prey rapidly like sharks and other fish. They might slowly propel themselves along, but usually they lie in … Read more
