    According to different species, they can live on land and in water as well. Some of the snakes can live on both. Different snakes have different attacking skills. Some kill their prey by injecting their venom before eating while some snakes attack their prey in such a bad way that it can stop blood supply and eat them.

    Snakes: Where do they live?

    Snakes are found everywhere in the world except Antarctica as snakes are cold-blooded animals, so they cannot survive there. They are found in freshwater sources, land, seas, marshes, oceans, tropical forests, deserts and even under old buildings. Snakes want to stay safe from the outside world and find a hole to stay there. They always find area that has minimum disturbance.

    Life Cycle of Snakes

    • Stage 1 – The Egg

    After mating of male and female snakes, females store male sperm in their oviduct for 1 or 2 months. After fertilization, female snakes lay eggs. A female snake can produce 10 to 15 eggs. These eggs are white in color, large, soft and like leather. Female snakes guard these eggs before hatching.

    • Stage 2 – Young Snake

    When the egg breaks, a young snake emerges. These young snakes are known as Snakelet. They are hatched from eggs by breaking the eggshell with their teeth or if sufficient heat is given to the eggs. Young snakes shed their skin four times a year so that they can enter the adult stage. During this stage, they eat smaller reptiles and rodents

    • Stage 3 – Adult Snake

    Adult snakes shed their skin one or two times a year. Adult snakes hunt prey for survival. They are sexually mature with a span of 2 to 3 years.

    Characteristics of Snakes

    Some of the characteristics of Snakes are given below:

    • Snakes are reptiles that don’t have wings and limbs.
    • Snakes evolved from limbed lizards back in the Jurassic era, as they have some traces of hindlimbs.
    • Snakes have horny scales all over the body.
    • Snakes cannot produce sound as they don’t have a vocal cord or larynx, but they can hiss.
    • Snakes don’t have any moveable eyelids.
    • They don’t have any ears, so they can’t receive any sound waves.
    • They shed their skin many times a year.
    • Snakes have an organ that secretes venom.
    • They have breathing systems developed as tracheal lungs.
    • In snakes, organs are placed side by side and not oriented bilaterally.
    • Snakes have backward teeth, which are fused with the head bones.

    Movement in Snakes

    Different snakes make different movements. There are four types of movements as per the zoologists.

    • Serpentine Method

    Generally, snakes move through serpentine methods on land. They don’t have limbs. So they bend and unbend by using their muscles, which creates serpentine motion. In snakes, scales are present in the lower part of their body, touching the ground, and they use these scales for this motion. When a snake moves in a serpentine motion, hurdles cannot stop them from moving. Most snakes move by this method.

    • Concertina Method

    This method is useful for moving in tight spaces. Snakes hold tightly their back portion and extend their front portion using the back as a pivot. Then, the snakes straightened their front portion to move the unbraced back portion forward.

    • Side Winding

    This is a very difficult movement for snakes to move on the ground. Side Winding is useful to move on slippery or loose surfaces. Mostly snakes living in desert areas use Side Winding to move on sand. In Side Winding, snakes make a diagonal displacement by bending and unbending instead of moving forward. This movement is useful for snakes living in muddy areas, swamps and deserts.

    • Rectilinear method

    This movement is used by snakes to move closer to anything suspicious or prey. This is a slow movement. Snakes use contraction and relaxation of muscles and make soundless movements by using front-facing slow bending motion. The surface is gripped by the belly scales.

    Snakes and Venom

    Marine snakes are more venomous than the snakes living on land. This venom is also extracted to make medicines. The buccal cavity is where the sac is present in which venom is produced. This sac is connected via a duct to the front canine teeth. The amount of venom that a snake wants to inject into a prey can be controlled by an adult snake, but a baby snake takes time to develop this capability and inject more venom than required.

    Snakes don’t waste their venom on bigger things that they can’t eat. Therefore 40% of the snake bite is defensive. Sometimes snakes only bite to threaten and no venom is injected by snakes. A rattlesnake is an example of this type, as it is a shy snake. Rattlesnakes only attack when molested. The same is done by Indian cobras.
