Interesting Facts About Snakes: Slithering Wonders of the Animal Kingdom

Size matters

The reticulated python holds the title for the longest snake, with some individuals reaching lengths of over 30 feet. In contrast, the Barbados threadsnake is the smallest snake, measuring a mere 4 inches long. The heaviest snake, the green anaconda, can weigh over 500 pounds.

Venomous and non-venomous

A majority of snakes are non-venomous, relying on constriction or their flexible jaws to subdue their prey. However, there are several venomous species, such as the inland taipan, the most venomous snake in the world, and the notorious black mamba snake, one of the deadliest snakes in Africa.

Lateral undulation

Snakes primarily use lateral undulation, a side-to-side movement, to navigate across smooth surfaces. However, arboreal snakes, such as vine snakes, have developed unique ways to move among trees.


Snakes, like all reptiles, are ectothermic, meaning they rely on external sources to regulate their body temperature. This makes them more active in warmer climates and less active in colder climates.

Jacobson’s organ

Snakes have a special organ called Jacobson’s organ that allows them to “taste” the air using their forked tongue. They collect scent particles and transfer them to the roof of their mouth, where this organ is located, to detect prey, predators, or potential mates.

Live birth

While most snakes lay eggs, some species, such as boa constrictors and viviparous snakes, give birth to live young. This adaptation is particularly useful in colder climates, where eggs might not survive.


Snakes shed their skin in a process called ecdysis. During this shedding process, they also replace the protective scales covering their eyes, known as eye caps or spectacles.

Fearsome fangs

Pit vipers, a group of venomous snakes that includes rattlesnakes and copperheads, have a heat-sensing organ located between their eyes and nostrils that helps them detect warm-blooded prey.

Snakes in New Zealand

Interestingly, New Zealand is one of the few countries in the world without any native snake species.

Snake bites

While snake bites can be dangerous, especially from venomous species like coral snakes, most snake bites are from nonvenomous snakes and are not life-threatening to adult humans.

These are just a few of the many interesting facts about snakes.

These fascinating creatures have a complex nervous system, unique adaptations for capturing prey, and have been the subject of myths and legends for millennia.

As you learn more about snakes, you may even find yourself wanting a pet snake, such as a corn snake or ball python.

Despite their fearsome reputation, snakes play an essential role in ecosystems as meat eaters and help control populations of small mammals and rodents. So, let’s celebrate the amazing diversity and incredible adaptations of these slithering wonders.
