10 Incredible Snake Facts – AZ Animals

Snakes are generally considered to be one of the deadliest animals in the world, and with over 3,400 species of snake, there is a great deal to learn about these creatures. Although we know many exciting things about them already, scientists are still studying these fascinating reptiles. Therefore, we have compiled a list of 10 incredible facts that you must know about snakes. Let’s get started! 

1. There are no snakes in New Zealand

Although we have such a large variety of snakes, none of them live in New Zealand. Yeah! The entirety of the nation of New Zealand is free of land-dwelling snakes. The reason for this is the complex and ever-changing climatic conditions in the region that make it incredibly difficult for snakes to live there. However, New Zealand does get occasional visits from two water snakes, namely: The yellow-bellied sea snake and the yellow-lipped sea krait. These snakes, however, don’t visit for a lengthy period because the waters in New Zealand are typically too cold for them. 

2. Snakes get their heat from external sources

Snakes are ectotherms, which means that they are cold-blooded and do not generate heat internally. They need external sources like the sun to help them heat up and gain the energy to go about their daily functions. When they fail to get this, they find it difficult to carry out tasks like movement or even food digestion. This is why snakes generally seek warm places to live. It is also why late at night, it is not uncommon to find snakes on sidewalks and roads trying to get heat from the asphalt.

3. Snakes can go months without eating 

When it comes to food, snakes have far more endurance than humans and other mammals. They do this by reducing their energy consumption and failing to digest stores of protein until much later. Some snakes are so good at conserving energy that they limit their metabolism rate by up to 72%. This means that some snakes can go up to a year without food. This trait boosts the survival chances of snakes in the wild. It also makes them incredibly flexible and deadly predators. 

4. Some snakes don’t lay eggs

Snakes are reptiles and they are normally expected to lay eggs. However, while a good number of snakes do lay eggs (in fact about 70% of snakes), some do not lay eggs but produce their young ones live. Snakes that don’t lay eggs usually live in colder climates because there is usually no suitable place for the mother to brood on the eggs. Therefore, these snakes keep the eggs within them and only deliver them after they have hatched. This gives the semblance of live birth. 

5. Canada is home to the largest gathering of snakes

Canada is a real home to many species of snakes with over 25 species of snakes living in the nation. Furthermore, the Narcisse Snake Dens of Manitoba, Canada is the largest gathering of snakes that you will find anywhere in the world. Over 75,000 snakes come together to mate during springtime in these snake dens. 

6. Snakes are generally venomous and not poisonous 

The chances that you have heard someone say that a snake is poisonous are very high. However, experts have pointed out that the vast majority of dangerous snakes are not poisonous but simply venomous. The difference between these two is that a poisonous animal releases harmful toxins when you eat it, while a venomous one is one that only transfers toxins through a bite or a sting.

Most snakes can be eaten with no deadly consequences, therefore, they are not poisonous. The exception to this is the garter snake that stores the poisonous toxins of its prey thereby making it deadly to eat. Interestingly the bite of the garter snake is quite harmless. 

7. The inland taipan is the most venomous snake in the world

The inland taipan delivers a nasty cocktail of toxins that is certain to immobilize its victim when it strikes. Some of the toxins that are contained in the venom of this snake include taipoxin, a complex mix of neurotoxins, procoagulants, and mycotoxins. The effects of a strike from the inland taipan include muscle paralysis, breathing problems, muscle damage, and hemorrhage in blood vessels. 

The good news is that the chances that you will run into one is low, and it generally has a peaceful temperament. The inland taipan is typically brown colored with a blackhead. 

8. Snakes do not have eyelids 

Snakes do not have eyelids, which means that they do not have to blink or even close their eyes. Instead of eyelids, a thin clear membrane covers their corneas, called spectacles or brilles and this is what helps to protect their eyes.

9. Snakes have four types of movements 

When you imagine a snake moving, chances are that you imagine it slithering through the grass and no other way. However, experts have pointed out that snakes have three other ways by which they move apart from this. The four movement types are: 

  • Lateral Undulation (Slithering) 
  • Concertina Locomotion
  • Sidewinding 
  • Rectilinear Locomotion

10. Snakes have internal ears 

Of course, you have not seen a snake with an external ear but that is no reason to believe that snakes are deaf. They do have an internal bone that functions like an ear through which they can pick up vibrations and sounds. However, they still don’t hear extremely well, so, noise-making may not be the most effective way to scare a snake away. 

Additionally, even though their ears may give them information about predators and prey approaching, their tongues are their primary tool for hunting and staying aware of their surroundings. They use it to sense chemical signatures that give them information about prey and predator.
