What Is a cassowary?

Cassowary

The cassowary is a large, odd-looking bird that lives in the thick forest of Australia and New Guinea.  A fully grown cassowary may be five feet tall and weigh two pounds or more.

Like the African relative the ostrich, the cassowary cannot fly.  All that remains of its flight feathers are a few spiny quilts, but it can sprint at speeds of at nearly 40 miles per hour for its long powerful legs, when it danger.

A bony helmet on its featherless head  helps it butt through the heavy underbrush.  Tough bristle like feathers that cover it body serve as a form of armor as it crashes headlong the forest.

A threatened cassowary can be a dangerous foe.  All three of the toes on each foot are armed with knife-sharp claws which can be a deadly weapon in a flight.  Usually, these shy birds are  heard more often than soon in their dense forest home.  They call by snorting and bellowing. – Dick Rogers

What is a crayfish?

Crayfish

Crayfish are small fresh-water shell fish that look like miniature lobsters.

If you have ever played by the bank of stream or pond, you may have seen a small animal that looked like a miniature lobster living at the bottom of the water near the shore.

What you saw was a fresh water shell like known as a crayfish. It is easy to see that the crayfish, sometimes called crawfish or crawdad, and the saltwater lobster are close relatives.

Both have 10 legs.  The front legs end in large pincers. These pincers are used to catch any prey that comes near,  as well as for defense.  The four other pairs of legs are used for walking.

The crayfish escapes from danger by swimming backward through the water with quick flips of its fan-like tail.  Like the lobster, the crayfish hatches from an egg.  A hard shell covers its soft body like a suit of armor.

Several times before it is fully grown, the crayfish must shed its outgrown shell and grow a new and larger one. – Dick Rogers

How does a snail grow its shell?

Snail

The shell grows in an ever-widening spiral as the snail continues to add new shell material to its shell during its lifetime.

You’ve probably seen a common garden snail peeking out of its shell as it slowly creeps along on a slick pathway of ooze.

Where did the snail get its shell?  It was born with a tiny shell just the right size for its body.  The shell serves as a suit of armor to protect the snail’s soft body.

As the snail grows, it oozes a slimy shell liquid that hardens into shell, and so the shell grows with the snail. The snail gets its shell-building materials from its food.

There are many kinds of snails, in almost every part of the world.  Some live only on land, some live in lakes and ponds, and others live deep in the ocean. The most snails are hatched from tiny eggs and look very much like their parents when they are born.

Most snail shells are shaped like coiled spirals.  Some are brightly colored with gay stripes.  Some snails grow shells that are no bigger than a pinhead.

But the biggest shells belong to the sea snails called conchs.  Their shell grow to be more than a foot long. – Dick Rogers
