Snake information, Snake history, and types of snakes in 2021

In this article, we will talk in brief about Snake information, Snake history, and types of snakes in 2021. Snakes have always been mysterious creatures for us and not only snakes, but every creature is mysterious in itself.

Snake is a long, limbless, carnivorous reptile. Which are found in both water and land. Snakes are found almost everywhere in the world except in some cold places like Antarctica, Ireland, Iceland, New Zealand, Greenland, etc.

The snake needs warm places or sunlight to stay active continuously. Therefore snakes are not found in these places because this place is not suitable for keeping the snake alive.

So let’s start, our today’s topic Snake information, Snake history, and types of snakes in 2021.

Snake Information

Snakes don’t have legs. He drags it forward with the help of his lower part. Snakes do not have eyelids, so their eyes are always open. Snakes are found in both venomous and non-venomous forms.

Its lower jaw is divided into two parts so that it can open its mouth in large size. Its upper jaw has two hollow teeth and these teeth have two holes that are connected by a venom sac. As these teeth go inside the victim’s body, the venom spreads throughout the body.

There are 3000 species of snakes found all over the world. Out of which about 250 species are found in India. Of which 60 species are such that are poisonous and whose bite can kill humans.

Snakes eat frogs, lizards, birds, rats, and other snakes. It sometimes swallows even larger animals.

The snake is a cold-blooded creature that cannot regulate its own body temperature. It varies according to the season.

It cannot be completely dependent on food, it also needs an adapted environment to survive. It can survive even with less food. Many snakes can live without eating for several months after eating once.

The snake does not eat its prey by chewing it, it swallows it whole. Most snakes are capable of swallowing an animal several times larger than their head with the help of their lower jaws.

Snake History

Snakes as a species are around 130 million years old. The first indications from early fossils place them in the Cretaceous period but the fossil evidence is inconclusive as small reptiles don’t leave good clear fossils as their small bones break down easily and become scattered.

However, it is largely believed that the split genetic split between lizards and snakes happened around the Cretaceous period.

The earliest fossil records of the ancestors of snakes and lizards appeared as long ago as 200 million years, during the Triassic period along with the first dinosaurs.

Snakes and Lizards are classified as Reptiles and form a class of vertebrate animals that sit between fish and amphibians on one side and birds and mammals on the other side.

Early fossils of snake-like animals showed that they were short and heavy and were a combination of features from both lizards and snakes as we know them today.

Unfortunately, the link between these early reptiles and modern-day snakes is lacking evidence and incomplete and is based largely on theory.

It is most popularly believed that snakes evolved from a primitive burrowing type of lizard that would feed off subterranean creatures and avoid larger surface-based predators.

Early snakes would probably have lost the use of sight as their world was in total darkness. Similarly, ears would have been impractical and modern snakes developed a mechanism to detect sound through vibrations and sophisticated abilities for smelling scents and acute touch sensors.

Today, there is no family of lizards that provides a conclusive link between lizards and snakes. The Legless Amphisbaenians, or worm-lizard, was once thought to be a lizard evolving into a snake but research has discovered unique differences in this species that indicates it has evolved separately from lizards and snakes.

There are about 3000 species of modern snakes broken into 11 families and 354 genera or sub-family. Snakes form one of the four sub-orders of the Reptile class called Squamata, the others being;

Chelonia – tortoises and turtles,
Crocodylia – crocodiles and alligators
Rhynchocephalia – Tuatara.

Squamata includes lizards, amphisbaenians, and snakes. Snakes form a sub-order of Squamata known as Serpentes – hence the term serpents which is derived from the Latin name serpens, a crawling animal or snake.


In more generic terms the classes of vertebrate animals are organized into six classes:

1.    Mammals
2.    Birds
3.    Reptiles
4.    Amphibians
5.    Bony Fish
6.    Cartilaginous Fish

Reptiles have unique characteristics that make them different from all other vertebrates. The most recognizable characteristic is that all reptiles have scaly skin, they respire (breath) by means of lungs and they are cold-blooded. No other vertebrate possesses this unique combination of characteristics.

Snakes and their reptilian families increase in size with geographic locations closer to the equator. This is believed to be a result of the increased activity throughout the year due to climates that provide higher temperatures throughout the year.

There are also many more species located in warmer climates than in cooler climates. Also, as altitude increases temperatures fall so there are fewer species of snakes (and other reptiles) in regions of high altitudes.

In spite of the constraints due to environmental preferences and needs, remarkably, snakes have populated a very high percentage of the earth’s surface. They are here to stay.

Based on the remains of snakes’ fossils, it is believed that the history of snakes is very old. Researchers believe that giant snakes existed in the time of dinosaurs. In the history of snakes, snakes like Titan Boa also existed.

Based on the structure of the snake’s body, it is believed that the snake was born from a lizard. With the passage of time, the legs of the snake disappeared.

After the extinction of the dinosaurs, there has been an explosive increase in the number of snakes. Even today giant snakes are found. Seeing such giant snakes, it seems that snakes like Titan Boa will also exist.
