Spiders use two different kinds of threads to spin their webs. One kind is sticky, and is used to catch the flies and insects spiders like to eat. The other kind of thread is a non-sticky, or silky, thread. It is on the non-sticky threads that the spider walks when it wants to get to … Read more

All spiders produce silk threads which are used to construct their webs. The silk is produced in the spider’s silk glands with the help of organs called spinnerets. By using different spinnerets, the spider can decide whether the thread will be thick or thin, dry or sticky, beaded or smooth. When the silk is first … Read more

If you see a shrew in a field or marsh, you might mistake it for a mouse until you spot its long, sharp nose. The shrew is one of the smallest mammals, only 3 to 6 inches long, with some weighing no more than a penny. Shrews are covered with short, dark hair and live … Read more

Almost, but not quite. Since moles live in underground tunnels, which they burrow, or dig, themselves, they have no need to see well. Their eyes are small, and a layer of fur and skin droops over them. In other ways, too, the mole’s body is suited for burrowing. A mole’s large, strong front feet can … Read more

Although wolves do attack people, for the most part, they avoid them. However, these gray, black, or red dog-like animals are great hunters. First they howl to get their pack together. Sometimes a pack will consist of about six wolves, but together, they are enough to chase and tire a deer and then kill it. … Read more

It is not its temper that makes a rhinoceros charge an intruder, but its poor eyesight. If it cannot recognize something, it will take no chances, but rush at it like a living tank, fast and furiously, ready to bite. The “horn” at the end of the rhino’s long nose, which can vary from 1 … Read more

Many farmers still use scarecrows in their cornfields and gardens to scare away crows, but while this “make-believe man” might keep the large black birds away for a while, crows are really not easily frightened and soon return to the fields and even perch on the arms and head of the scarecrow. The old custom … Read more

Although rabbits and hares belong to the same family and look so much alike that they are mistaken for each other, there is a difference between them.

The keenest sense of smell in the insect world, and in fact in all nature, belongs to the male silkworm moth. This valuable moth uses its two antennae mainly to locate the female and can detect her signal, or smell, up to 6.8 miles away, amazing for an insect only about 1 inch long.

The caterpillars of the silkworm moth are the remarkable creatures responsible for making the threads from which man manufactures shiny, beautiful silk cloth. Today, almost all silk is cultivated on silk farms in Japan, China, and other countries of the Far East, where mulberry trees grow, since it is the leaves of this tree which … Read more

For the very sensible reason that they’re hungry and they like the taste of wool. The eaters are actually the larvae, or caterpillar stage the moths go through before they get their wings.

The tough, dried, twisted string used today in making violin strings, tennis racket strings, strings to thread looms, and thread for surgical stitches is NOT made from a cat’s guts and never has been. Most catgut is made from the intestines of sheep and hogs. These intestines are cut into long ribbons, then cleaned and … Read more

The top speed man has run is about 25 miles per hour; the fastest dog, the greyhound, reaches a speed of 40 miles per hour; racehorses have been timed at 50 miles per hour; and antelopes can go close to 60 miles per hour. But none of them can come close to the world’s fastest … Read more

Bats are not blind. Like many animals, they are born blind, but gain eyesight from the time they are seven to nine days old. The saying, “blind as a bat,” probably arose because of the way bats fly around, darting here and there at night. Actually, the bat is hunting insects, which people cannot see … Read more

A sloth is a small South American mammal which moves about very slowly, when it moves at all.

Though it lives in the sea, the whale is a warm-blooded mammal. It must breathe oxygen from the air to live. When surfacing, the whale takes in oxygen through the blowhole on top of its head. Then, filling its large elastic lungs which are connected to the blowhole, the whale dives to feed. While underwater, … Read more

The longest-lived creature in the insect world is the termite queen. She has been known to live for over 50 years. During that time, the queen can lay over 30,000 eggs each day, so in her 50 years of life, it is possible for her to give birth to half a billion children!

The turtle lives longer than any creature on earth, well over 200 years (and some scientists believe 300), for the very same reason that the tortoise won the race with the hare in the famous fable.
