How did the jackrabbit get its name?

Jackrabbit

The jackrabbit gets its name from its long ears, which resemble those of a jackass, or donkey.  Though it was originally called a “jackass rabbit,” this animal’s name has long since been shortened to “jackrabbit.”  The jackrabbit is a hare, and not a true rabbit.

It has longer ears and longer legs than a rabbit.  This large hare can run up to 45 miles an hour to escape its enemies.  While running it often makes great leaps, or “spy hops,” as if to check on the pursuer.  Jackrabbits hide most of the day, and come out at night to eat plants and farm crops.–Dick Rogers

What Is A Coelacanth?

Coecalanth

Coecalanth

A coelacanth (pronounced SEE, luh kanth) is a large rare fish from deep in the oceans around Africa.

What makes the coelacanth so unusual is that it is perhaps the world’s most primitive bony fish. It was once thought to have been extinct. But in 1938, a living coelacanth was caught by a fisherman off the east coast of Africa.

Almost unchanged since its origin, this strange-looking fish was bright blue in color. It was five feet long and weighed 125 pounds. It had leglike fins, probably used for crawling about in the sea, and its head was covered with thick scales.

If the fisherman had found a living dinosaur, he would not have attracted more attention in the scientific world.

Scientists  knew the coelacanth only from fossils and had assumed that the prehistoric fish had died out 60-million years ago!

Since the discovery of a live coelacanth, several more of these “living fossils” have been found.Dick Rogers

How do starfish eat?

Starfish

A starfish’s mouth, underneath its flat body, leads directly into a large, bag-like stomach. The starfish can push its stomach out through its mouth.  Starfish like to eat clams and oysters.  Encircling a clam with its powerful arms, the starfish attaches its sucker-like tube feet to the clam’s shell.

With ever-increasing force, it pulls the two halves of the shell apart.  Then, the starfish pushes out its stomach and digests the food.  When the starfish has completed its meal, it pulls back its stomach, and leaves only an empty clam shell behind.–Dick Rogers

Do fish drink the water they live in?

Fish

Fish consume the water they inhabit if it agrees with their system.  Since the bodies of freshwater fish are much saltier than the water they live in, they don’t drink.

They are in danger of too much water entering their bodies, diluting their body fluids. They urinate often to get rid of any extra water that soaks into their bodies.

Saltwater fish, however, drink large amounts of water, since the salty sea water absorbs moisture from their bodies, causing dehydration.  These fish eliminate excess salt through their gills and very concentrated urine.–Dick Rogers

Do Squirrels remember where they hide all of their nuts?

Squirrels don’t always remember where they have hidden all their nuts.  Every autumn,  the tree squirrel gathers and hides acorns and other nuts.  It knows that food will be hard to find during the winter months.  It buries small stores of nuts in many different places.

That way, if other animals find and eat some, the squirrel will have others.  The squirrel depends on a keen sense of smell to help it relocate the hidden stores.  Yet many of the nuts are forgotten or abandoned by the squirrel.  Then the nuts may take root and grow into new nut trees.–Dick Rogers

Why do pigs wallow in mud?

Pigs wallow in mud because it feels good to them.  Pigs have no sweat glands in their thick skin to serve as a cooling system. Wallowing in mud helps pigs to keep cool on a hot day.  The coating of mud also adds a protective layer against the sun and helps keep off biting insects.

Pigs have a reputation of being dirty and stupid because they wallow in mud. But they keep themselves cleaner than most other farm animals.  Pigs have been shown to be the most intelligent of all hoofed animals.  They can be taught to perform tricks and can even become pets.–Dick Rogers

Why do cats retract their claws?

Cats retract their claws in order to keep them sharp for catching mice and other prey.  A cat has a special movable joint at the end of its toes that enables the claws to move in and out.  The claws move out when they are needed.  When not in use, the cat conceals its claws in little sheaths on its toes and walks softly on the pads of its feet.  Claws that can be pulled back so that the sharp points are protected are called retractile claws.  Cats sharpen their claws by raking them on furniture and free trunks to remove any ragged edged on the claws.–Dick Rogers

What are the whiskers for on an animal’s face?

Whiskers

The whiskers on an animal’s face are organs of touch.  They help the animal sense what going on around it.  Scientists call whiskers vibrissae (vi-BRIS-see). These long, sensitive hairs are most helpful to animals that prowl about in dark places.

A cat’s whiskers brush against objects the cat might not see as it hunts at night.  Whiskers help some animals find food.  The whiskers on a seal’s face are helpful in detecting fish in the dark or cloudy water.  And the thick whiskers on a walrus’s upper lip help it to feel for clams in the ocean bottom.–Dick Rogers

Is the prairie dog really a dog?

Prairie Dog

No, despite its name and its barking call, the prairie dog is actually a member of the ground squirrel family.  The prairie dog lives in underground burrows in the western United States. These burrows have so many tunnels that people refer to them as towns.

Hundreds of prairie dog families may live in these towns.  A mound of dirt surrounds the entrance to each burrow.  A prairie dog usually stands guard at the entrance to its burrow.  If it spots danger, the prairie dog barks loudly, and they all scramble to their homes for safety.–Dick Rogers

How can birds perch on electric wires without getting shocked?

Birds

A bird does not receive a shock when it lands on an electric wire because it lands on only one wire.  Electricity takes the path of least resistance—it flows through some materials much more easily than others.

It is simply easier for the electricity to continue along the metal wire than it is for it to detour through the bird.

If the bird landed on two wires with different voltages, however, the electricity would flow through the bird from the wire with the higher voltage to the wire with the lower voltage, and the bird would be electrocuted.–Dick Rogers
