Some of the  species of snakes don’t have legs and some have but they are not fully developed and are non-functional. Snakes don’t have eyelids. There are over 3,000 species of snakes.

In this article on snake facts, you will learn a lot about snakes like their habitat, prey, reproduction, and some other interesting facts. So, without any further ado, let us begin our snake facts.

Snake Facts 1-10

2. There are more than 3,000 species present in 500 genera of snakes. Out of 3,000 species, 600 of them are venomous. 200 of 600 species can kill or seriously wound humans. 

3. Some non-venomous snakes also harm humans like pythons. They either constrict a man to death and eat him up alive. 

4. Almost all snakes have scales and are cold blooded meaning snakes should regulate their body temperature externally. 

5. The scales cover the snake completely including their eyes. Scales are thick and tough chunks of skin made up of keratin. 

6. Scales are useful for several reasons like trapping moisture in arid (dry) climates, reducing friction as it moves. 

7. Snakes had legs some 70 million years ago. 

8. The most dangerous snake on this planet is the saw-scaled viper. It bites and kills more people than any other snake in any year. 

9. The decollated head of a dead snake can bite even hours after death. Such bites have a lot of venom. 

10. They (snakes) evolved from a reptilian ancestor that had four legs – probably a land-dwelling lizard around 100 million years ago in the Cretaceous period.

11. Fear of snakes is called herpetophobia or ophiophobia. It is one of the most common phobias in the world. 1/3rd of humans are scared of snakes which implies that the fear of snakes is innate and evolutionary. 

12. Black mamba is considered to be the most advanced snake because it has a highly developed venom delivery system that no other snake has. It can strike up to twelve times at a stretch. However, a single strike is enough to kill an adult human. 

13. Some snakes have over 400 ribs whereas humans have only 24 ribs. 

14. If a human turns into a snake, he/she would be around four times longer and only a few inches thick.

22. Paul Rosolie, a naturalist, tried to be the first person to survive an attack of anaconda in 2014. He wore a designed carbon fiber suit provided with cameras, communication system, and a breathing system. However, he called it off because he observed that anaconda was breaking his arm as it was tightening its grip on him.

36. Snakes lie on roads or rocks so that they can absorb the warmth that these rocks and roads hold (rocks absorb heat from the sun) and the heat/warmth help snakes to move quickly. If the temperature drops below 50 degrees Fahrenheit, the snake’s body can’t work properly. 

37. The number of offspring of a snake is decided by the amount of food it consumes. The higher the food consumption, the higher number of offspring. Arafura snakes eat the least and produce only one egg in a decade.
