Snakes are fascinating and diverse animals that have been around for millions of years. They can be found on every continent except Antarctica, and have adapted to various habitats and climates. Snakes are also one of the most feared and misunderstood creatures, despite their important role in the ecosystem. In this article, we will explore some fun facts about snakes that will rattle your mind.
Fun facts about snakes
1. Snakes are legless reptiles
Snakes evolved from a four-legged reptilian ancestor, most likely a small, burrowing, land-bound lizard, about 100 million years ago. Some snakes, such as pythons and boas, still have traces of back legs, called vestigial limbs, that are visible as tiny spurs near their tails. Snakes had back legs for 70 million years before losing them completely.
2. Snakes have a unique anatomy
Snakes have a flexible skull and jaw that can unhinge and expand to swallow prey much larger than their head. Although they have no eyelids or external ears, snakes can sense vibrations and heat through special organs. They have forked tongues that can be used to smell and taste the air. Also, snakes have long, slender bodies with hundreds of vertebrae and ribs that support their muscles. They have scales that protect their skin and help them move.
3. Snakes shed their skin regularly
Snakes shed their skin a number of times a year, in a process called ecdysis. This helps them get rid of parasites, such as ticks and mites, and also allows them to grow. Young snakes shed their skin every two weeks, while adults do it once or twice a year. The complete outer layer is removed in one piece, as if taking off an old sock.
4. Snakes come in many colors and patterns
Snakes can be found in a variety of colors, such as green, blue, brown, red, yellow, and black. Some snakes have plain scales to avoid predators, while others have patterns that blend into their surroundings or warn potential enemies. Some snakes can even change their color to match their environment, such as the chameleon snake of Madagascar.
5. Snakes have diverse movement techniques
Snakes can move in different ways, depending on the terrain and the situation. On rough ground, they use lateral undulation, which is a wave-like motion that pushes them forward. On smooth surfaces, they use side-winding, which is a twisting motion that lifts and sets their body sideways.
In tunnels, snakes use concertina locomotion, a squeezing and extending motion that braces their back half against the walls while their front half moves forward. On trees, they use gliding, which is a flattening and curving motion that allows them to soar from branch to branch. When stalking, these creatures use rectilinear locomotion, which is a slow and stealthy motion that lifts their belly up, pulls it forward, and drops it down.
6. Snakes have diverse diets and hunting strategies
Snakes prey on a variety of animals, such as frogs, lizards, rodents, worms, snails, birds, insects, fish, and even other snakes. Some snakes use venom to hunt and kill their prey, such as cobras and vipers. Venom is a toxic substance that is injected through fangs into the victim’s body, causing paralysis, pain, or death.
Some snakes use constriction to hunt and kill their prey, such as pythons and boas. Constriction is a squeezing technique that wraps around the victim’s body, cutting off blood circulation and suffocating it. Furthermore, some snakes use ambushes to hunt and kill their prey, such as rattlesnakes and mambas. Ambush is a hiding technique that waits for the victim to come close, then strikes with speed and accuracy.
7. Snakes have different modes of reproduction
Snakes can reproduce in different ways depending on the species and the environment. Most snakes lay eggs, which they deposit in a warm and moist place, such as a burrow or a pile of leaves. Some snakes, such as cobras and pythons, stay near their eggs to protect them until they hatch.
Also, some snakes give birth to live young, which they carry inside their body until they are ready to emerge. This happens in colder climates, where eggs would not survive. Other species, such as the Brahminy blind snake, are parthenogenetic, which means they can reproduce without a mate. They produce clones of themselves that are all female.
8. Snakes are important for the ecosystem
Snakes play a vital role in the ecosystem, as they help control the population of rodents and other pests that can damage crops and spread diseases. They are also a food source for many animals, such as birds, mammals, and other reptiles. Snakes are indicators of environmental health, as they are sensitive to changes in habitat, climate, and pollution. They are also valuable for scientific research, as their venom and skin have medicinal and industrial applications.
9. Snakes are feared and revered by humans
Snakes have a complex relationship with humans, as they are often feared and hated, but also respected and worshipped. They are one of the most common phobias in the world, as about one-third of all adult humans are afraid of them. This may be due to an innate, evolutionary fear of snakes, or due to cultural and religious influences.
Snakes are also associated with many myths and legends, as they symbolize different things in different cultures, such as wisdom, fertility, healing, evil, or rebirth. Humans also exploit snakes, as they are hunted for their skin, meat, and organs, or captured for the pet trade. Snakes are also threatened by humans, as they face habitat loss, climate change, and persecution.
10. Snake population in snake Island
There is a part of the world where the ground is basically covered by snakes, It is estimated that there’s at least one snake on every square meter. It is the island of Ilha da Queimada Grande, also known as Snake Island, off the coast of Brazil. The island is home to an estimated 2,000 to 4,000 golden lancehead vipers, one of the most venomous snakes in the world. The snakes are so abundant and dangerous that the Brazilian government has banned visitors from the island, except for a few researchers and navy personnel.
