Bird Alarms - Snakes immune to their own venom

Bird Alarms

Birds produce mainly three types of alarms. One is a short distance alarm and is hard to pinpoint. An example is the hawk alarm of robins. The second type is a clear shriek of despair piercing sound. The third is a hard-edged rattling call, which indicates aggression.

Are snakes immune to their own venom?

There are cases where snakes have been found dead, with their fangs buried deep in their own body. But, it is a mystery as to whether or not snakes are immune to their own venom. Some researchers conclude that snakes are immune to the effects of their own venom. Others declare that snakes are not immune to venom-their own, or another snake’s. they point out that when poisonous snakes fight, they do so by rearing up and ‘wrestling’ with each other, rather then that biting because they know they would be killed if they accidentally bit themselves.  

No snakes in Ireland - A look that kills

Did you know that there are no snakes in Ireland?

Legend has it that St. Patrick drove all the snakes from Ireland. Scientists however say, this is because snakes are bad sea travelers. During the last Ice Age snakes slithered into England while it was still joined to Europe. By the time they reached the coast however, the sea had melted, and Ireland was cut off. While lizards and tortoises crossed the sea on driftwood, snakes do not like traveling by sea, so they remained behind.

 

A look that Kills !

If you happen to be in front of a baboon, and if he blinks at you, do you know what it means? It’s an uncompromising ‘back off’! Baboons live in large troops, with many males constantly struggling for dominance. If a male wants to express dominance, he fixes his rival with a long hard stare. He then blinks rapidly, to say, ‘stay away’. Sometimes he yawns very dramatically, to scare his enemy by showing his sharp teeth!

Two Headed Snakes - Blue Mover

Two Headed Snakes

Two-headed snakes are very rare creatures, but not unheard of. Life is very difficult for such snakes. First, the two heads have to decide they are both hungry at the same time, and then they have to agree to pursue the same prey. Then they might fight over which head gets to swallow the prey. To make it even more complicated, sometimes one head will attack, and try to swallow its second head. This did happen at the San Diego Zoo some years back, and the snake died.

Blue Mover
The blue tongued skink has a blue tongue which it constantly flicks in and out. Therefore, it is known as the blue mover. The blue mover looks clumsy, but it can move quickly. The blue mover gives birth to live young.

Amazing

Did you know that cockroaches were on the planet even before the dinosaurs appeared?
While many species of animals have become extinct, cockroaches have survived to this day. In fact, it is said that even a nuclear blast cannot destroy all of them! Amazingly, cockroaches can live a month without food, but only a week without water. What is more, a cockroach can live a week without a head, and it dies after a week due to lack of water!

Crocodile tears ?
When someone pretends to cry without feeling sad we say they are shedding ‘crocodile tear’. Do you know why this phrase is used? It is because when a crocodile looks as though it is crying, it is actually not crying at all. It is only getting rid of the excess salt in its body through its tear glands!

Turtle on Tree !
Did you know that there is a turtle that can climb trees? Well, though it may seem far fetched, the Chinese big headed turtle can do so! It has long claws and a long tail, and though it looks clumsy, it can scramble up a tree for safety if it feels that there is danger.
