What is the smallest mammal?

Shrew

The smallest mammal in the world is the shrew.  The tiniest member of the shrew family, the Mediterranean shrew, is about as long as your little finger and weighs less than a penny!  Shrews live in most parts of the world.

If you see a shrew in a field or garden, you might mistake it for a mouse until you spot its long, sharp nose.  These active animals are almost always hungry.  They must eat more than their own weight in insects, worms, and snails each day just to stay alive.  Their sharp teeth make it easy for them to kill and eat their prey.–Dick Rogers

Why are piranha fish so dangerous?

Piranha

In South American rivers swims one of the world’s most dangerous fish—the piranha.  This savage fish is only ten or so inches long, but its teeth are so sharp and its jaws are so strong, it can chop a piece of flesh from an animal or a human as neatly as a razor. Piranhas often travel in schools of several hundred.

Their diet usually consists of other fish.  But if an animal happens to be in the water near a school of hungry piranhas, they attack and devour it instantly.  Animals as bit as a horse have been eaten down to a bare skeleton in only a few minutes. – Dick Rogers

What is a Barracuda Fish?

Fiercest Fish

Barracuda are pikelike saltwater fish.  They are sometimes called “tiger of the sea” because of their pierce nature.

One of the fiercest of fishes is the barracuda.  These slender, pikelike fishes with jutting jaws and razorlike teeth live in the warmer waters of the Atlantic and Pacific oceans.

There are several kinds of barracudas.  The largest of them is the great barracuda.  This big fish may grow to be 6 feet long.  It is sometimes called the “tiger of the sea.”

It seems to fear nothing and may attack anything that moves in the water, including man.  In fact, many people think some barracudas are more to be feared than most sharks.

When the barracuda finds a school of fish, it slowly stalks them, then dives into their midst, biting and slashing with its sharp teeth and powerful jaws.

Barracuda are among the fastest fishes.  A four-foot-long barracuda can swim 25 miles an hour of more, for short distances. – Dick Rogers

 

Why do beavers build dams?

Beavers build dams to create ponds in which to build their beaver lodges.  Beavers are brown-furred animals with flat, paddle-like tails.  They live in ponds and streams.  Beavers are known for their skill at cutting down trees with their sharp teeth and building dams.

Beaver

The purpose of the beaver dam is to hold back water and make it form a pond in which the beaver can live.

To build its dam, the beaver gnaws downs trees and drags and floats them to the dam site.  It fastens the logs and twigs in place with rocks and mud until a strong barrier is built.

An ordinary beaver dam may be a 5 feet high and 200 or more feet long.

The beaver builds its lodge with branches and mud, too.  A beaver’s lodge looks like a pile of sticks in the pond.  It is really a one-room house.  The floor of the room is just above the water line.  To enter, the beaver must swim through an underwater door in the floor.  Inside the lodge, protected by thick walls and by underwater doors, the beaver is safe from most enemies.  – Dick Rogers

 

What is a peccary?

Peccary (pronounced PECK a ree) is a wild animal that looks very much like a small, tailless pig covered with thick, bristly hair and it has a piglike snout.

Peccaries live chiefly in the forests of South America and can be found as far north as southern rooting in the ground for much of their food and eating roots, fruits and worms, as well as insects and poisonous snakes.

Peccary

Peccaries avoid people if left alone.  If cornered, they can fiercely defend themselves with their sharp teeth.  With their keen ears and noses they are difficult for the hunter to find.

When disturbed, peccaries give a barklike alarm call and make a rattling sound by chattering their teeth.

Peccaries can give off a strong, evil-smelling, musky odor when excited.  For this reason, they are sometimes called “musk hogs.”

Peccaries are also known by such other names as “wild hogs” or “javelinas” (HAH vuh LEE nah).  Peccaries raised in captivity make gentle and interesting pets. – Dick Rogers

 

What is a sea lamprey?

Sea Lamprey

A sea lamprey (pronounced LAM pree) is an eel-like water creature.  It grows up to three feet long.  Its mouth is a cuplike sucker lined with sharp “teeth”.

Fishermen dread the sea lamprey because of its destructive eating habits.  It is a parasite—it eats other fish by attacking itself to the other fish with its strong sucker mouth.

It scrapes a hole in the fish with its teeth and tongue, which also has teeth, and then sucks the blood out of the fish.

A fish attacked by a sea lamprey usually will die.

Sea lampreys are normally saltwater creatures, but they swim up freshwater rivers and into lakes to spawn.

Sometimes they remain in the inland lakes and never go back to the sea.

When this happens, they can become serious pests.  Sea lampreys have destroyed many important food fishes, such as trout and mackerel, in the Great Lakes.-  Dick Rogers

What is a leech?

Leech

Some swamps and ponds contain leeches, worms that can cling to fishes, animals and ever to persons.  Leeches may grow from ½-inch to 4 or more inches long.

Like many worms, they have soft, flat bodies divided into segments.  On the leech’s head is a sucker like mouth equipped with three saw-shaped teeth.  A second sucker is located at the hind end of the leech.

The leech attaches itself to the host by means of its suckers.  Then, with the mouth sucker, it sucks up the blood through three little holes which it makes in the skin with its sharp teeth.

In a single meal a leech may eat three times its own weight in blood.  One meal may fast several months.

Not all leeches suck blood.  Some feed instead on worms and other small animals that live in the water.  During medieval times bloodsucking leeches were used by physicians to draw blood from patients in attempts to cure them. – Dick Rogers
