Why do cats eyes shines at night?

Cat's Eyes

Most of us have seen a cat’s eyes glowing beside the road at night.  The glow is simply a reflection of a car’s headlight.  The back of a cat’s eye is lined with a special mirror-like material called “tapetum.”  

This shiny layer helps the cat to see in dim light by catching even the faintest gleam of light and concentrating it on the retina.  It also reflects the light of a car’s headlights and causes the cat’s eyes to glow brightly.  

The cat’s special kind of eyesight allows it to do most of its hunting at night.  A cat cannot see in complete darkness any more than we are.  – Dick Rogers

Why do snakes stick out their tongues?

The old belief that a snake stings with its tongue isn’t true.  The flickering tongue is actually a delicate sense organ that helps the snake to smell.  A snake’s tongue is long and forked at the end.  It darts through a small hole in the front of the snake’s mouth.  

As the snake moves along the ground, its flickering tongue senses odors in the air.  The tongue relays the information to special organs in the mouth which are linked to the snake’s sense of smell.  By picking up the odors, the tongue helps the snake to locate food and sense the presence of enemies. – Dick Rogers

What Is A Killer Whale?

Killer whale is the name of a large porpoise.  It gets its name from the popular belief that it is a blood-thirsty killer.  It has a glossy black back and a white underside.  These creatures often measure 30 feet in length and can weigh 10 tons.

Killer whales get their name from the widely held belief that they will attack any creature in the sea – and, like man, are some of the few animals that kill for sport.  Though they have the reputation as killers, killer whales have not been known to attack swimming men or boats.  

Killer whales often hunt in packs, and will attack other whales many times their own size.  Their mouths and throats are big enough to swallow seals, penguins, and young walruses whole.  Only the tusked adult walrus holds the killer at bay.

When killer whales see a seal on a floating chunk of ice, they rush up under the ice and crash into it, knocking the victim into the water.  Killer whales also feed on fish and even sea birds.  Killer whales are found in all the oceans of the world, but prefer to live in the cold arctic and Antarctic waters.-Dick Rogers
