How do snails eat?

Snail Eating

The garden snail comes out mostly at night to feed on leaves and other plant food.  The snail’s mouth is under its head.  It has no chewing jaws.  To help it get its food, the snail’s mouth is equipped with a special tongue that is covered with hundreds of tiny teeth.

It is called the “radula” (RAJ-uh-luh).  The rasp-like radula shreds and scrapes bits of food into the snail’s mouth as the snail crawls along.  The snail finds its food with two pairs of tentacles on its head.  The shorter pair is used for smelling on the tip of each of the longer tentacles is an eye. – 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

How does an octopus eat?

Octopus

The octopus has a powerful parrot-like beak in its mouth that it uses to crack the hard shells or crass and oysters.

The octopus is a sea animal with a soft, bag-shaped body.  It gets its name from two Greek words that mean “eight feet.”  We call its eight feet “arms.”

The octopus dwells on the ocean bottom where it crawls about on its arms, searching in every crack and crevice for its favorite food of shrimp, crab, and mussels.

On each of the eight arms there are two rows of cup-like suckers which help the octopus grab and hold very tightly to anything it catches.

The arms do not squeeze and prey, but pull it toward the creature’s mouth.

An octopus has two very strong jaws that look like the beak of parrot.  It uses its jaws to crush crab shells and to tear apart the food it eats.

The long, snakelike arms and large, unwinking, strangely human eyes give it a frightening look.  Most kinds of octopus are only about as big as a man’s fist, and do not attack people.

Some however, have poisoned jaws and bites from even a small octopus. – Dick Rogers

Which is the largest shark?

The largest known living shark is the whale shark which is often more than 50 feet long and weights several tons.  It is also the biggest of all fishes.

(The whale, which is larger and resembles a fish, is not a fish but a mammal.)

Shark

Whale sharks can easily be recognized by the lines of pale spots on a grayish body, as well as by their huge size.

Curiously enough, this biggest shark of all is completely harmless to man.  Though it has jaws wide enough to swallow a man, the whale shark lives peacefully in the warm sea, eating seaweed and small fish.

Sharks have the reputation for being among the most dangerous of sea creatures.

There are many kinds of sharks, and while some are quite fierce, the surprising thing is that most kinds of sharks are quite harmless.

The great white shark is sometimes called the most dangerous of sharks.  It may grow to be 35 feet long and will have no hesitation about making a meal of a swimmer. – 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

 

What are harvester ants?

305611645_VJKkC-SWe are all familiar with ants.  Ants are found scattered far and wide over the world.

There are red ants and lack ants.  Others can be brown or yellow.

Some ants are hunters.  Others may be farmers, dairymen or carpenters.

Ants known as harvester ants are large, long-legged red or black ants that live in warm, dry, sandy places.

They get their name because they harvest, or gather, seeds of weeds and other plants and store them in their underground nests for a future supply of food.

They have large, crushing jaws for breaking seeds.

To build rooms underground to live in and sore seeds, the harvesters carry grains of sand outside and pile them into a big outhill over the nest.

The harvester’s home is easy to spot because of a trash heap of discarded seed husks piled outside the entrance.

If stored seeds get wet, the ants spread them in the sun to dry.
