Snakes are good friends of farmers, forming a key link in the food chain. They play an important role in maintaining the balance of the ecosystem and the food web. While snakes keep the population of pests, such as rats and insects, under control, they can also fall prey to large birds, mongooses, wild boars, and raccoons. Thus, they are both predators and prey.

Snakes are carnivorous reptiles. They have supple skin covered in scales, a forked tongue, eyes that never blink or close, and an elongated leg-less body. They are vertebrates, meaning they have a backbone, and many species of snakes have skulls with highly mobile jaws and a vestigial pelvic girdle (1). Snakes are thought to have evolved during the Jurassic period.

Some Famous Types Of Snakes

There are around 3,000 snake species in the world, of which around 600 are venomous (2). Each species has its own special characteristics. Let’s learn about some of the most common species.

  1. King cobra: King cobras are the longest venomous snakes. These fast-moving snakes have amazing agility, and their color depends on the location where they live. They are most commonly found in India, southern China, and Southeast Asia.

  1. Reticulated python: Reticulated pythons do not have any venom and are seldom known to bite. However, they wrap around and suffocate any prey they find. They have very complex color patterns, including olive green, black, white, and gold, and a diamond-like geometric design that allows them to camouflage with their surroundings. They are native to Southeast Asia.

Are Snakes Blind And Deaf?

No, snakes are not blind, but they usually have poor eyesight. Their vision is adequate to track movements but is not very sharp.

Snakes such as pythons, copperheads, and rattlesnakes have openings called pit holes in front of their eyes. These pit organs can detect infrared thermal radiation, which helps them sense the heat given off by warm-blooded prey even in the dark.

Snakes do not have external ears but have inner ears linked to their jaw by a middle ear bone. This set-up helps them sense vibrations and hear low-frequency sounds (3).

How Do Snakes Detect Preys And Predators?

 Snakes smell prey through their forked tongue. When a snake flicks its tongue in the air, it gathers chemical particles and sends them to a sensory organ called the vomeronasal system, enabling the snake to determine the presence of prey and predators around it. Snakes such as the python and pit vipers sense their prey using their infrared heat-sensing organ (4).

How Do Snakes Move Without Legs?

Snakes develop several modes of locomotion depending on their native environment. Most snakes use their belly scales to grip surfaces and move (5).

The major modes of locomotion in snakes are as follows:

  • Lateral undulation: In this mode, the body of the snake flexes alternately to the right and left, resulting in rearward-moving waves. It is the sole mode of locomotion in water and the most common mode of locomotion on land.
  • Sidewinding: In this mode, all of the body-segments that are oriented in one direction are in contact with the ground, while the other segments are lifted up, resulting in a “rolling” motion. This mode helps the snake move in slippery mud or sand.
  • Rectilinear: In this mode, the belly scales are lifted and pulled forward before the body is placed down. The ribs of the snake do not move in this mode, making this the slowest mode of locomotion. This mode is often employed by pythons, boas, and vipers as it makes the prey harder to detect their movement.

How Do Snakes Feed?

Snakes are strictly carnivorous and feed on lizards, frogs, eggs, birds, worms, insects, fish, small mammals, and other snakes. Usually, snakes cannot bite and tear their food into pieces, so they swallow the prey whole. Snakes have a very flexible lower jaw, allowing them to open their mouths wide enough to swallow their prey, even if it is larger in diameter than the snake itself. The body size of a snake influences its feeding habits.

Some snakes have a venomous bite, which is used to kill their prey before eating it, while others kill their prey by constriction. Snakes become dormant while digesting their food. The surrounding temperature plays a large role in digestion as snakes are cold-blooded animals (ectothermic). The digestive enzymes of snakes dissolve and absorb everything but the prey’s hair, feathers, and claws, which are excreted as waste (6).

What Is Venom?

The venom in venomous snakes is modified saliva that is delivered through the fangs. It is used to immobilize, injure, and kill their prey. The venom acts as a poison for their prey. It also serves as a pre-digestant that initiates the breakdown of food into soluble compounds, facilitating proper digestion (7).

What Is Molting?

The process wherein a snake sheds its scales is called molting (ecdysis or sloughing). It helps the snake replace the old and worn skin and get rid of parasites, such as mites and ticks.

What Is Molting

Snakes stop eating and move to a safe place before molting. In snakes, the complete outer layer of skin is shed in one layer. Usually, the cast skin peels backward over the body from head to tail in one piece. After molting, a thicker and brighter layer of skin is formed (8).

50 Facts About Snakes For Kids

 Here are some fascinating facts about snakes (9) (10) (11).

  1. The only places where there are no snakes are Iceland, Greenland, New Zealand, Ireland, and Antarctica, as snakes are cold-blooded creatures.
  1. The African egg-eating snake has bony protrusions on the inside edge of its spine. The snake uses these to break the shells of the eggs.
  1. The venom of a king cobra is strong enough to kill an elephant.
  1. Venomous snakes tend to be brightly colored, which acts as a warning for predators to stay away from them.
  1. A viper snake species of Fer-de-lance has been recorded swallowing a prey 1.6 times its body weight.
  1. Snakes have more than 200 teeth that point backward. They are used to bite and grip their prey securely.
