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 are mollusks?

Mollusks

If you have ever collected shells at the seashore, probably most of the shells you found were once the homes of living animal called mollusks.

The most familiar mollusks are probably clams, oysters, octopuses, squids, snails and slugs.

Most mollusks are related, or alike, in certain ways.  Mollusks are soft-bodied animals without bones.

Most kinds of mollusks, including clams and oysters, have hard shells that protect their soft bodies.

Other kinds, such as cuttlefish and squids, have no shells that show.  A special shell grows inside their bodies.

Octopuses and some slugs have no shell at all.

Mollusks live in most parts of the world.  Some, such as snails and slugs, live on land.  Others are found in rivers, lakes and ponds.  But the greatest number of mollusks are ocean dwellers.

Mollusks furnish us with food.  Their shells are made into many products, including buttons and jewelry.  – Dick Rogers

 

What is a snapping turtle?

Snapping Turtle

The common snapping turtle of North America is a large bad tempered turtle having a powerful jaws which snap with great forces.  This tells us how the snapping turtle gets its name.

Snapping turtles live in muddy streams and swampy ponds.  A full-grown “snapper” may weigh 30 pounds and have a shell a foot long.

It may look clumsy, but it can move quickly on land and can make short leaps on its strong legs to snaps its food.

When this turtle is attacked, it snaps with lightning speed, its strong, sharp-edged jaws can inflict dangerous bites.

A close relative of a common snapper is the big alligator snapping turtles that lives in the rivers of the gulf states.  They are the biggest snappers of all.

A big one can weigh 140 pounds or more.  A snapping turtles shell can be 2 feet long and is covered with rows of bumps, much like the skin of a real alligator. – Dick Rogers
