Snake venom is used to make anti venom & many other life saving drugs. An anti-venom serum is actually a small quantity of the venom itself which when injected into an animal or human affects only slightly triggering an allergic reaction to it. The allergic reaction will allow anti bodies to be formed and thus immunity to the venom is developed.
All snakes are carnivorous. Snakes do not chew their food and have a very flexible lower jaw. They can open their mouths wide enough to swallow their prey whole, even if it is larger in diameter than the snake itself. Snakes do not normally prey on people, unless startled or injured, preferring instead to avoid contact. In fact, the majority of snakes are either non-venomous or possess venom that is not harmful to humans.
Snakes shed skin on a regular basis and it is a part of its growth
Snake’s tongue is used to sense the surroundings. Snakes smell by using its forked tongue to collect airborne particles then passing them to the Jacobson’s Organ, a special organ in the mouth for examination. The fork in the tongue gives the snake a sort of directional sense of smell.
Snakes can survive without eating food for several days. Snakes have a slow metabolic rate and thus can survive without eating for many days at a stretch, after a sumptuous meal. Snakes like King cobras can survive many months without food.
