There are around 3,400 known species of snake worldwide, with the snake being found on every continent apart from the polar regions.

Though they do not have a voice, they can hiss. Most snakes live on the ground, others live in the water, and a few live under the soil. Like all reptiles, snakes need the heat of the sun to control their body temperature. That is why most snakes are in the warm, humid tropical regions of the world.

They have a long, slender body, and are very mobile in their own way. Most of them live in the tropics. Very few snake species live beyond the Tropic of Cancer or Tropic of Capricorn, and only one species, the common viper lives beyond the Arctic Circle. Their skin is covered with scales. They can see well enough, and they can taste scents with their tongues by flicking them in and out. They are very sensitive to vibrations in the ground.

The snake can grow anywhere from 10cm in length, to the enormous anaconda snake that can reach lengths of up to 30ft long! There are two ways that snakes kill their prey, either the snake has a poisonous bite or the snake will wrap itself around the prey to constrict it.

Most species of snake inhabiting colder regions in the Northern Hemisphere, will hibernate through the cold winter months. The snake tends to mate in the spring time.

Venom

Most snakes are nonvenomous. Those that have venom use it mainly to kill and subdue prey rather than for self-defense. Some have venom potent enough to cause painful injury or death to humans. Non-venomous snakes either swallow prey alive or kill by squeezing.

Snake venom is highly modified saliva containing zootoxins that facilitates the immobilization and digestion of prey, and defends against a threat. It is injected by unique fangs after a bite but some species are also able to spit venom.

What How Why

What are the most precious stones?

When the magma cools, the material which it contains solidifies in the form of crystals. Precious stones are crystals with particular characteristics of colour, hardness and the way they can reflect the light. They are used in making jewellery.
