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

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 barracuda?

Barracuda

One of the fiercest of fishes is the barracuda.

These slim, alert fishes with jutting jaws and razorlike teeth can be found living in the warmer parts of the Atlantic and Pacific Ocean.

There are several kinds of barracudas.  The largest of them is the great barracuda.  This bit fish may grow to be a 6 feet long.

It has strong jaws and a mouthful of razor-sharp teeth that may be nearly an inch long.

It is sometimes called the “tiger of the sea”.  It fears nothing, and will attack anything that moves in the water, including man.

Sharks are often blamed for wounds really made  this fearsome fish.  In fact, many people think barracudas are more to be feared than most sharks.

When it finds a school of fish, the barracuda slowly stalks them.  Then it dives into their midst, biting and slashing with its sharp teeth.  – Dick Rogers
