Is a Snake a Reptile

Snakes have an anatomy that is truly unique, which they use to their advantage. In reality, just contemplating them is difficult to tell what they are and how we define them! Are reptiles, mammals, amphibians, or something else entirely?

Read on to learn more about snakes and how they are classified scientifically. We’ll also discuss where they live, what they eat, and other fascinating information about these lovely serpents that you may not have known.

What are reptiles?

The scales and capacity to lay eggs are characteristics of reptiles, which are cold-blooded animals.

Crocodiles, snakes, lizards, and turtles are among the animals. Reptiles are snakes, as the name implies.

Reptiles are tetrapod creatures with backbones and four legs, with snakes being the lone exception. They are tetrapod vertebrates, hence they all have backbones. Reptiles frequently lose the exterior layer of their skin because their skin is composed of scales.

Some people are quicker than others, but it’s primarily due to the temperature in their surroundings, where they reside!

Crocodiles, snakes (check out our Dangerous Snakes of the World Worksheet), lizards, and turtles are all well-known examples of reptiles. These have probably been mentioned, but there are a slew of reptiles that you may not be familiar with. Below are some of the different reptile species!


Snakes can be found almost anywhere except Antarctica, Iceland, Ireland, Greenland, and New Zealand; there are more than 3,000 species on the planet. Venomous animals number about 600, but only about 200 of them are capable of killing or severely injuring a human.

Venomous snakes dispatch their victims by swallowing them alive or constricting them to death, from harmless garter snakes to the not-so-harmless python. Nearly all snakes swallow their meal whole, in sometimes astonishingly huge portions. Whether they do so by biting with venom or squeezing, they nearly all do it.

Snakes are cold-blooded reptiles that must externally control their body temperature because almost all of them have scales. Scales help to hold moisture in dry regions and reduce friction as the snake moves, among other things. Several snake species have been found that are mostly scaleless, but have scales on their bellies, nonetheless.

Are Snakes Reptiles Or Amphibians?

Reptiles are a kind of animal that includes snakes. Crocodiles, lizards, and turtles are among the animals in this group. Reptiles raise their body temperature by lying in the sun or lowering it by crawling into the shade, and they are cold-blooded creatures. Their body temperature adapts to that of the environment.

Snakes in colder areas have to hibernate throughout the winter as a result of this. Until the weather becomes warm enough for them, they will discover burrows or caves and fall asleep.

Snakes come in over 2,900 different varieties across the globe. Deserts, woods, oceans, streams, and lakes are among the places where they live. Snakes can be found on the ground, in the trees, and in water.

Snakes are only found north of the Arctic Circle or in Antarctica because the ground remains frozen year-round. Snakes are not found on some islands, such as Ireland and New Zealand.

Reptiles evolved from amphibians some 300 million years ago, making them one of the oldest groups of animals! They evolved from being aquatic to living predominantly on land, gradually branching off from their amphibious forebears. Snakes, on the other hand, are excellent swimmers and highly aquatic today.

Squamata order, which includes lizards and snakes, is a taxonomic category that we can divide snakes into. Snakes are classified as part of the Serpentes suborder within that group. In this category, there are nearly 4,000 different snake species!

Snakes have more joints in their skulls and exceptionally stretchy jaws to allow them to consume extremely huge prey, which distinguishes them from lizards. Their organs are positioned differently from those of lizards because their bodies are so long and thin.

Just one of the snakes’ lungs is functional. Many snakes have tiny vestigial remnants on either side of their vent called pelvic or anal spurs, despite the fact that they have no legs.

Sea snakes

The majority of snakes dwell on land, however roughly 70 species dwell in the Indian and Pacific Oceans. While they are timid, gentle, and their fangs are too short to cause significant injury, sea snakes and their cousins, kraits, are among the most poisonous snakes in the world.

Interactions between individuals

Snakes are predominantly solitary in their habits in both the tropical and temperate environments. The season’s only social events are the denning and mating aggregations, which are, for the most part, alone. In this regard, sea snakes (Hydrophiinae) are different, as they may often be seen in enormous swarms, which appears to imply a drive to congregate.

Large clusters of female sea snakes congregate in seawall caverns around parturition time, although this might be a result of the availability of a secure environment for the juvenile to be born rather than sociable behavior.

In temperate regions, females of certain species have a tendency to deposit their eggs at a single location. Snakes do not exhibit cooperative hunting, as some mammal and bird species do; instead, they rely entirely on individual hunting for food.

This is another consequence of availability; in the tropics, where hiding places abound, finding more than one snake at a time under a log or a rock is uncommon.

There is no growth of social behavior in snake populations, no establishment of social hierarchies, no territoriality, and maybe no dominance. With the exception of a few weak examples, this is true. There is no indication that either snake retains awareness of its dominance after combat dance (see below), despite the fact that it establishes a dominant individual for a short time.

A social structure cannot be built on a dominance that must be reestablished every time.

Where Do Snakes Live?

Snakes now call every continent except Antarctica home. Ophidiophobes will be sad, but snake lovers will be ecstatic! Snakes are highly adaptable, despite the fact that most species prefer hot, humid, tropical climates due to their cold-blooded nature. From woods and swamps to deserts and savannas, they have evolved to live comfortably in a variety of environments.

Several species may be terrestrial, arboreal, or fossorial, meaning that the majority of their time is spent on land. Arboreal snakes, for example, include flying snakes and vine snakes. In densely wooded forests, they have adapted well to living high up in trees.

Some snakes, such as sea snakes, have evolved to spend most of their lives in water. To swim quickly and efficiently, they have broad, paddle-like tails. In addition, they can hold their breath underwater for long periods while breathing via their skin!

Snakes and humans

Because of ignorance about snake nature and place in the natural order, snakes are widely misunderstood and mistrusted.

Venomous snakes (bites snakes that use their fangs to inject chemicals into victims) have given the whole group a bad reputation because most individuals cannot tell the dangerous from the innocuous.

Just around 300 species are venomous, and only around half of them are capable of causing a fatal bite.

Although snakebite fatalities worldwide are estimated to be 80,000–140,000 yearly, the majority of fatalities occur in Southeast Asia, owing to substandard medical care, victim malnutrition, and a plethora of venomous species.

In the United States, there are approximately 8,000 venomous snakebites each year, but only around 10 or so people die from venomous snakebites each year. Bee stings kill 10 times as many people in Mexico as snakebites every year.

How snakes hunt

Snakes use their forked tongues to smell their surroundings, flicking them in different directions. That allows them to detect when danger or food is nearby.

Other ways snakes can detect food include: The heat given off by warm-blooded prey is sensed by openings known as pit holes in front of their eyes. Rodents and other scurrying creatures transmit vibrations to the bones in their lower jaws.

Since their lower jaws unhinge from their upper jaws, snakes can eat creatures up to three times bigger than their head. The victim is held in place by teeth that face inward once it is in a snake’s mouth, preventing it from escaping.

Are Snakes Carnivores?

All snakes must consume other creatures to live and cannot digest vegetation, hence they are carnivores. Most of them have a sluggish digestion and metabolism, so they need to eat only once or twice per week in general. The kind of creatures a snake consumes, however, varies depending on its size, species, and habitat.

Little rodents, birds, and their eggs are the main foods of smaller snakes like garter snakes and corn snakes.

Gaboon vipers, for example, can eat guineafowls, rabbits, and frogs because they are bigger species. Reticulated pythons and king cobras, for example, are among the world’s largest snakes and may kill creatures like goats, wild boars, and even other snakes!

The majority of a snake’s diet is determined by its habitat. Fish and amphibians are the primary sources of food for aquatic snakes such as kraits and water moccasins. In the meantime, small burrowing rodents like mice, moles, and even tiny lizards may be eaten by terrestrial and fossorial snakes.

Birds and their eggs are more likely to be eaten by arboreal snakes, which spend most of their time in trees.

How Many Kinds Of Snakes Are There?

Almost 3,900 different species of snakes currently make up the Serpentes suborder! Within this suborder, there are over 20 different snake families and 500 distinct genera. These smaller groups exist to help us categorize snakes based on physical features and behaviors that they share.

Snakes have a Latin taxonomic name that describes their genus and species, much as other animals do. Thamnophis sirtalis is the scientific name for a common garter snake. Since the genus it belongs to is Thamnophis, and the species within that genus is known as sirtalis, this is the case.

The size of snakes varies greatly. Little threadsnakes, just a few inches long, are the world’s tiniest and smallest snakes. On the other hand, large snakes may attain lengths of more than 20 feet and weigh almost 150 pounds, such as the green anaconda and reticulated python!

Snakes used to be much, much bigger! The gigantic Titanoboa cerrejonensis, for example, grew to be 40 to 50 feet long and weighed up to 2,000 pounds about 60 million years ago. That is bigger than a typical school bus!


Snakes’ skins are shed about once a month, and this is known as ecdysis, which allows for development and removal of parasites. They slither out of their skin head first, leaving it inside-out, and rub against a tree branch or other object.

Most snakes lay eggs, however some, such as sea snakes, give birth to live young. With the exception of pythons, which incubate their eggs, very few snakes pay any attention to their eggs.

The IUCN Red List of endangered snake species lists about a hundred species, the majority of which are threatened by habitat destruction caused by development.

Five snake species have the ability to fly, which makes ophidiophobes uneasy.


Snakes may take use of the facts that the females are accessible, concentrated, and receptive since mating occurs immediately after emergence from hibernation. Pairing and copulation are simple because the males are equally concentrated.

Nuptial tubercles, which are used to stroke or massage the female and, presumably, to arouse her sexually, can be found on males of several species.

The male employs a rubbing technique to excite the female, and in some species, a muscle ripple travelling down the male’s body may substitute for a lateral caress. Courtship dances performed by snakes, in which the bodies are intertwined and up to one-third of the coils are lifted off the ground, ebbing and flowing with silent elegance, have been described in several sources.

Sadly, the snakes were not caught and sexed in many of these studies, leaving the observer to believe that a male and female were present. Two guys are believed to be participating in a competitive activity for the purpose of acquiring females throughout the breeding season.

The front of the bodies entwine and are lifted higher and higher off the ground until one snake overpowers the other, much as in the courting dance.

The fight dance is said to be essentially a homosexual encounter in which each guy attempts to have sex with the other. In any case, once a hemipenis is inserted into the female’s cloaca (a common urogenital chamber located immediately anterior to the anus), copulation is achieved after a brief courtship.

The hemipenis is a mirror-image intromittent organ located at the base of the male’s tail, posterior to the anus, and is exclusively used for mating and empties straight into his cloaca.

Either hemipenis may be utilized in copulation, but it must first be turned inside out before being used. The organ is primarily engorged with blood in order to achieve this.
