100 Species of Snake Organised by Family and Subfamily
Snakes are one of the most colourful and diverse groups of animals on the planet, consisting of 18 families, over 500 genera and almost 4,000 species. In this fast-paced guide, we’ll explore 100 species of snake from constrictors such as boas and pythons to the highly venomous viper and elapid families, common snakes such as vine and rat snakes, and some of the most weird and wonderful species like the elephant trunk snake and the blind snake. Let’s dive in!

Family: Boidae | Boas
Boas are a family of large non-venomous snakes that kill by constriction. There are 5 sub-families of boa, the most famous of which are true boas found in Central and South America and the Caribbean. The holes in the side of their faces are heat-sensing organs known as pits, used to detect prey.
01 – Green anaconda | Eunectes murinus
The green anaconda is found in the Amazon and Orinoco basins and is the world’s heaviest snake, reportedly weighing up to 227 kg or 500 lb. Their name derives from a Latin word meaning “of mice” although they consume a much larger variety of prey.

02 – Common boa | Boa constrictor
The common boa or boa constrictor has a much larger range than the anaconda being found throughout much of South America. They have intricate camouflage and are also known as the red-tailed boa for the beautiful colour gradient on their tail.

03 – Rainbow boa | Epicrates cenchria
Rainbow boas are typically much darker than the common boa, exhibiting a deep red hue and are named as such due to their iridescent sheen, giving their skin a rainbow-like reflection in certain light.

04 – Emerald tree boa | Corallus caninus
More colourful yet still is the emerald tree boa, which is part of a family of snakes called neotropical tree boas. Interestingly, juveniles start their lives in various shades of red and orange and then turn to emerald green after around 9-12 months, a process called ontogenetic colour change.

05 – Javelin sand boa | Eryx jaculus
A particularly odd-looking boa and the last in this family that we’ll discuss, the javelin sand boa is found in Europe, the Middle East and North Africa. They are much smaller than true boas, only growing to around 80 cm in length.

Family: Tropidophiidae | Dwarf boas
06 – Panamanian dwarf boa | Ungaliophis panamensis
Dwarf boas are a separate family of snakes also known as thunder snakes containing two genera and 36 species. The Panamanian dwarf boa is found in Nicaragua, Costa Rica, Panama, and Colombia and grows up to around 30-60 cm in length.


Left & Right: Panamanian dwarf boa | Milan Zygmunt / Shutterstock
Family: Pythonidae | Pythons
Pythons are very similar to boas, containing some of the largest and most colourful snakes in the world. This family is made up of 10 genera including “true” pythons, reticulated pythons and tree pythons. They are found in sub-Saharan Africa, much of Asia and Australia.
07 – Burmese python | Python bivittatus
The Burmese python is the second heaviest snake in the world, weighing just north of 180 kg or 400 lbs. Although they are now an invasive species in Florida, they live mainly in Southeast Asia and are particularly stunning in their albino form, displaying yellow and white skin.

08 – Ball python | Python regius
The ball or royal python is native to west and central Africa and usually displays fairly standard colouring. They can be bred to exhibit a wide variety of colour morphs including the butter ball python, the pied royal python and the entirely white blue-eyed leucistic ball python.

09 – Reticulated python | Malayopython reticulatus
The reticulated python is the longest snake in the world, reportedly measuring up to 10 meters or over 30ft in length. The word reticulated means constructed, arranged, or marked like a net or network, referencing the intricate pattern on this species’ skin.

10 – Green tree python | Morelia viridis
The spectacular green tree python is pythonidae’s answer to the emerald tree boa. In this particular species, juveniles can be both yellow in colour or a deep orange-red before turning green at around 1 year old.

Family: Viperidae | Vipers
Vipers are a group of venomous snakes, much smaller than boas, who have long fangs used to inject venom into their prey. Vipers’ venom is hemotoxic, which is less deadly than the neurotoxic venom used by elapids that we’ll discuss later on.
Subfamily: Crotalinae | Pit vipers
Pit Vipers are the largest subfamily of vipers, which include lanceheads, rattlesnakes and moccasins, and are distinguished by the presence of their pits, which are found between the nostril and eye on each side of their face.
12 – Eyelash pit viper | Bothriechis schlegelii
The eyelash pit viper is one of the most colourful in this family and can be found in a bright yellow to shades of green and white. They are known as such for a row of superciliary scales above their eyes giving the appearance of eyelashes, which protect them in their arboreal environment.


Left: Yellow Eyelash Pit Viper | Roy H / Shutterstock & Right: Eyelash Pit Viper in Costa Rica | Honesttraveller / Shutterstock
13 – Fer-de-lance | Bothrops atrox
The common lancehead otherwise known as the fer-de-lance has similar colouration to a boa or python and are found in central and South America. They are one of the most venomous of the viper family, a weapon they use to hunt rodents in banana and coffee plantations.

14 – Sunda Island pit viper | Trimeresurus insularis
The Sunda Island pit viper is the first of three colourful vipers that we’ll explore in the Asian lancehead genus. They can be found in a variety of colours although by far the most striking variation has a blue-green skin that is rare to find in other species.


Left: Sunda Island pit viper | Cavan-Images / Shutterstock & Right: A baby Lesser Sunda pit viper I Wayan Sumatika / Shutterstock
15 – McGregor’s pit viper | Trimeresurus mcgregori
The McGregor’s pit viper is native to the Batanes Islands of the Philippines and can be found in an entirely white variation. The species is named after Richard Crittenden McGregor who survived being bitten while collecting the type specimen.


Left: A white McGregor’s pit viper | reptiles4all / Shutterstock & Right: Yellow McGregor’s pit viper | reptiles4all / Shutterstock
16 – Beautiful pit viper | Trimeresurus venustus
The brown-spotted pit viper also known as the beautiful pit viper is one of the most aptly named snakes in the world. They display a chequered green and brown skin with turquoise highlights and are found in southern Thailand.

17 – Western diamondback rattlesnake | Crotalus atrox
Diamondback rattlesnakes are one of the heaviest venomous snakes in the world weighing up to 6.7 kg or 15 lbs. They are a type of pit viper who exhibit a rattle to warn predators, which they will use before striking. The Western Diamondback Rattlesnake is found in the southern US and Mexico.

18 – Rock rattlesnake | Crotalus lepidus
The rock rattlesnake is much smaller and has lighter skin. There are four known subspecies including the banded rock rattlesnake and the mottled rock rattlesnake who use their patterned skin for camouflage.


Left: Banded rock rattlesnake | Matt Jeppson / Shutterstock & Right: Mottled rock rattlesnake | Rusty Dodson / Shutterstock
19 – Eastern copperhead | Agkistrodon contortrix
The Eastern copperhead is the first of two American moccasins that we’ll look at. Its Latin name contortrix comes from the Latin contortus which means twisted, intricate or complex, referring to the bands of colour on its skin that contort in width.


Left: Copperhead | Fabio Lotti / Shutterstock & Copperhead viper (Agkistrodon contortrix) | Giannis Papanikos / Shutterstock
20 – Cantil | Agkistrodon bilineatus
Cantils are another species of moccasin found in Mexico and Central America. They are around 60 cm or 24 inches in length and although they lack a rattle, they also vibrate their tails when threatened.

Subfamily: Viperinae | True/Pitless vipers
True or pitless vipers are distinguished by a lack of pits, the heat-sensing organ present in other members of the viper family. This family is often referred to as true adders, containing the day adder, night adder and puff adder genera.
21 – Rough-scaled bush viper | Atheris hispida
The Rough-scaled bush viper also known as the hairy bush viper is very unique, exhibiting raised dorsal scales that give it an almost dragon-like appearance. They are found in Central and East Africa in the Congo, Uganda, Kenya and Tanzania.


Left: Close up of a hairy bush viper & Right: A hairy bush viper in the rainforest | Mark Kostich / Shutterstock
22 – Variable bush viper | Atheris squamigera
The green or variable bush viper might just be the most colourful snake on this list. They are quite small with an average total length of 60 cm or 24 inches and can be found in a wide range of colours from green, yellow and reddish-orange to slate grey or black.


Left: Variable bush viper in its orange phase & Right: Two variable bush vipers | Mark Kostich / Shutterstock
23 – Many horned adder | Bitis cornuta
The many horned adder is a puff adder found in rocky desert areas in Southern Africa. Their name derives from the 2-5 raised scales above their eyes which give them a horned-like appearance not too dissimilar from the lashes of the eye-lash viper previously discussed.


Left: Many-horned adder from Springbok, Northern Cape | Willem Van Zyl / Shutterstock & The many-horned adder | Andre Coetzer / Shutterstock
24 – Desert horned viper | Cerastes cerastes
The desert horned viper lives on the other side of the continent in Northern Africa and is also found in the Middle East. Instead of multiple scales, their horns consist of a single scale, which makes them easily distinguishable from other species in their genus.


Left: Desert horned viper | Horia Bogdan / Shutterstock & Right: Desert horned viper in the sand | Mark Kostich | Shutterstock
25 – Spider-tailed horned viper | Pseudocerastes urarachnoides
The spider-tailed horned viper is the last viper we’ll cover; they are incredibly unique and are found only in a small area in western Iran. They have a spider-like tip to the tail, which they wave around to lure insectivorous birds into the range of their bite.


Left: The spider-tailed horned viper & Right: Close up of a spider-tailed horned viper’s tail | reptiles4all / Shutterstock
Family: Elapidae | Elapids
Elapids are the most venomous snakes on the planet. This family contains both terrestrial and aquatic snakes and, unlike the viper family who enclose their fangs in a sheath, the fangs of elapids are permanently erect and secrete powerful neurotoxins which attack nerve tissue. Terrifying!
Group: 7 x genera | Cobras
Cobra usually refers to a single genus containing 36 species, Naja, but can also refer to a group of 7 genera, the rest of which only contain 1-2 species including the King cobra, shield nose cobras and tree cobras.
26 – King cobra | Ophiophagus hannah
The king cobra is one of the most well-known snakes on the planet. It is not actually part of the cobra genus and is instead contained in its own monotypic genus. Furthermore, recent DNA analysis has shown that there may actually be multiple species of king cobra.

27 – Indian cobra | Naja naja
The Indian cobra is the first of three true cobras that we’ll look at. The species plays an important role in Indian mythology and culture but is part of the “big 4” snakes that inflict the most bites on the Indian Subcontinent.


Left: Indian cobra | Guillermo Pis Gonzalez / Shutterstock & Right: Close view of Indian cobra | RealityImages / Shutterstock
28 – Samar cobra | Naja samarensis
The Samar cobra is a particularly colourful cobra native to a few small islands in the Philippines. They prey upon small rodents and reptiles and have a beautiful black and yellow skin that make them easily recognisable from other cobras.


Left: Close up of a samar spitting cobra | reptiles4all / Shutterstock & Right: Samar spitting cobra | Sibons photography / Shutterstock
29 – Red spitting cobra | Naja pallida
The red spitting cobra is another very unique cobra exhibiting dark red scales and a black band around its neck. They are found mainly in East Africa and their venom is a combination of neurotoxic and cytotoxic which affects cell function.

31 – Cape coral snake | Aspidelaps lubricus
The cape coral snake is part of a genus of snakes commonly known as shield-nosed cobras or coral cobras. There are two subspecies, both of which are found in Southern Africa. They bridge the gap nicely between the cobras of this section and the coral snakes of the next.


Left: Cape coral snake from Springbok, Northern Cape | Willem Van Zyl / Shutterstock & Right: Coral shield cobra | Willem Van Zyl / Shutterstock
Group: 4 x genera | Coral snakes
Coral snakes are a group of snakes made up of old world and new world snakes. Old world coral snakes are made up of three genera and exist in Europe, Asia and Africa. New world coral snakes are made up of two genera and exist in the Americas.
32 – Eastern coral snake | Micrurus fulvius
The eastern coral snake is also known as the candy-stick snake, the coral adder or the American cobra but is not closely related to other cobras apart from being in the elapid family. They are relatively small, rarely surpassing 80 cm or 31 inches in length.


Left: Eastern coral snake | Jay Ondreicka / Shutterstock & Right: Venomous eastern coral snake | Mark Kostich / Shutterstock
33 – Australian coral snake | Brachyurophis australis
The Australian coral snake is different to the eastern coral snake in almost every way! Although they are still venomous, they are tiny, usually reaching about 38 cm or 15 inches and, being a burrowing snake, live mostly underground.


Left: Australian coral snake flickering its tongue | Ken Griffiths / Shutterstock & Right: Close up of Australian coral snake | Ken Griffiths / Shutterstock
34 – Blue Malaysian coral snake | Calliophis bivirgatus
The blue Malaysian coral snake is part of the oriental coral snake genus and is one of the most venomous, with venom glands extending up to 25% of the total length of their bodies. They are native to Southeast Asia and, interestingly, prey upon other snakes.

35 – MacClelland’s coral snake | Sinomicrurus macclellandi
The MacClelland’s coral snake is named in honour of the naturalist, John McClelland. There are 4 recognised subspecies and are found throughout much of east, south and Southeast Asia including the Ryukyu islands of Japan.


Left & Right: MacClelland’s coral snake, Vietnam | Dan Koleska / Shutterstock
Group: 7 x genera | Sea snakes/kraits
Sea snakes may refer to the single family or a collection of 7 families of aquatic snakes including sea kraits. These sea-dwelling serpents spend their lives in the shallow tropical waters of the Indian and Pacific oceans and all apart from one genus are unable to permanently exist on land.
36 – Yellow-lipped sea krait | Laticauda colubrina
The yellow-lipped sea krait is perhaps the most well-known sea snake with its distinctive black and blue striped skin. They have a yellow upper lip and snout, hence the name, and have a paddle-like tail used for swimming.


Left: Yellow-lipped sea krait | Rich Carey / Shutterstock & Right: Close up of a Yellow-lipped sea krait | Ethan Daniels / Shutterstock
37 – Black-banded sea krait | Laticauda semifasciata
The black-banded sea krait, also known as the Chinese sea krait, is similar in colour pattern but much lighter. They break the surface once every six hours to breathe and, like all sea snakes, are highly venomous; this species, in particular, are reportedly more deadly than a cobra.

38 – Yellow-bellied Sea Snake | Hydrophis platurus
The yellow-bellied Sea Snake is part of the main family of sea snakes, Hydrophis, which contains 36 other species. Most have a yellow belly and black back but they can also be found entirely in yellow.


Left: Close up of a yellow-bellied sea snake | NickEvansKZN / Shutterstock & Right: Yellow-bellied sea snake on the sand | NickEvansKZN / Shutterstock
39 – Olive sea snake | Aipysurus laevis
The olive sea snake is a particularly beautiful species. They feed on crustaceans, fish, and fish eggs and are preyed upon by sharks and ospreys. They are said to be the most toxic of all sea snakes with venom that breaks down their prey to aid with digestion.


Left: Olive sea snake swimming in coral | Gabriel Guzman / Shutterstock & Right: A large olive sea snake | DNC40 / Shutterstock
Group: Other Elapids
While we have discussed a few of the main groups; cobras, coral snakes and sea snakes, there are many other interesting genera of the highly venomous elapid family that we’ll group together such as mambas, brown snakes, taipans and death adders.
40 – Banded krait | Bungarus fasciatus
The banded krait is a particularly dangerous-looking member of the krait genus that is separate from the sea-dwelling kraits we discussed in the previous chapter. This particular species inhabits termite mounds in the countryside of eastern Asia.

41 – Black mamba | Dendroaspis polylepis
The black mamba is one of the most well-known and infamous snakes in the world. They are found in parts of sub-Saharan Africa and, in terms of venomous snakes, the black mamba is second only in length to the king cobra.


Left: A coiled black mamba | NickEvansKZN / Shutterstock & Right: Black Mamba hatching | NickEvansKZN / Shutterstock
42 – Western green mamba | Dendroaspis viridis
The western green mamba inhabits the coastal tropical forest and woodland regions of West Africa and is one of two species of green mamba—the other being the eastern green mamba found in East and Southern Africa.


Left: Western green mamba in green foliage | Prill / Shutterstock & Right: Western green mamba | Lubos Chlubny / Shutterstock
43 – Eastern brown snake | Pseudonaja textilis
The eastern brown snake can reach up to 2 meters or 7 feet in length and is considered to be the second most poisonous snake in the world. They are found in Australia and New Guinea especially in areas such as farmland with high populations of house mice.


Left: Highly venomous eastern brown snake | Ken Griffiths / Shutterstock & Right: Eastern brown snake in striking position | Ken Griffiths / Shutterstock
44 – Ringed brown snake | Pseudonaja modesta
The ringed brown snake is a close relative to the eastern brown snake and is distinguished by four to seven black bands dispersed throughout its body although these bands or rings are much less prominent on some individuals.

45 – King brown | Pseudechis australis
The king brown snake is not actually a brown snake, rather, it is the first of two black snakes that we’ll discuss. They are quite large growing up to 3.3 meters or 11 ft in length and are found in either a browny-black or a reddish-brown colour.


Left: King brown snake | Ken Griffiths / Shutterstock & Right: Juvenile king brown aka the mulga snake | Kristian Bell / Shutterstock
46 – Inland taipan | Oxyuranus microlepidotus
The inland taipan, which is also named the fierce snake, changes the colour of its skin depending on the season to aid with thermoregulation. It is endemic to Australia and is the most venomous species of snake in the world.


Left: Inland taipan in coiled position | Ken Griffiths / Shutterstock & Right: Yellow inland taipan in Australia | Ondrej Prosicky / Shutterstock
47 – Coastal taipan | Oxyuranus scutellatus
The coastal or common taipan is found in the coastal regions of Australia and on the island of New Guinea where there is a particularly colourful subspecies known as the Papuan Taipan, which has a much lighter body and an orange head.


Left: Hatchling coastal taipans | Ken Griffiths / Shutterstock & Right: Close up of a coastal taipan | reptiles4all / Shutterstock
48 – Tiger snake | Notechis scutatus
Tiger snakes are named so for the tiger-like bands across the length of their bodies. They are excellent swimmers and come in a wide range of colours depending on which part of Australia they are from.


Left: Close up of a tiger snake in the Perth region of Western Australia | Adam Brice / Shutterstock & Right: Eastern tiger snake in defence pose | Ken Griffiths / Shutterstock
49 – Common death adder | Acanthophis antarcticus
The common death adder is one of two death adders that we’ll explore and the last in the Elapid family. Death adders possess the longest fangs of any snake in Australia but, rather bizarrely, are currently threatened by an invasion of cane toads.


Left: Close up of Australian common death adder showing lure at tip of tail | Ken Griffiths / Shutterstock & Right: Common death adder in curled up position | Ken Griffiths / Shutterstock
50 – Desert death adder | Acanthophis pyrrhus
Desert death adders are extremely well camouflaged for their environment and can either be a brick red or more of a yellowish colour. They are found in central and western Australia where they prey upon lizards and small mammals.

Family: Colubridae | Typical snakes
Commonly referred to as typical snakes, Colubridae is the largest snake family comprising 8 subfamilies, 258 genera and over 1800 species. The vast majority of these snakes are non-venomous, although there are a few species that have caused human fatalities.
Subfamily: Natricinae
The first subfamily that we’ll explore is Natricinae. It contains 37 genera and includes grass snakes, water snakes and garter snakes. They are found on most continents with the exception of South America and only a few that exist in Australasia.
51 – Grass snake | Natrix natrix
Grass snakes are strong swimmers and feed exclusively on amphibians. They spend winter underground where they are not subject to freezing and males will bask in the sun in the spring to raise their body temperature before mating.


Left: Grass snake on pond with water lily leaf | Dr Pixel / Shutterstock & Right: Close up of a grass snake | Gucio_55 / Shutterstock
52 – Common garter snake | Thamnophis sirtalis
Garter snakes are relatively small skinny snakes, with a maximum total length of 1.4 meters or 4 feet. Their venom is very mild but they are efficient hunters often catching fish and tadpoles. They are present in North America where there are 13 subspecies.


Left: Headshot of a common garter snake | Paul Tessier / Shutterstock & Right: A group of garter snakes mating in Narcisse, Manitoba, Canada | Jukka Palm / Shutterstock
53 – San Francisco garter snake | Thamnophis sirtalis tetrataenia
The San Francisco garter snake is by far the most colourful subspecies of garter snake, exhibiting blue, red and black stripes along the length of its body. They are currently listed as endangered with some researchers estimating that only 1-2 thousand remain in the wild.

54 – Buff striped keelback | Amphiesma stolatum
The buff striped keelback is a particularly docile snake, it is said to be the Asia version of the American garter snake being found in South and Southeast Asia. They tend to dwell in areas with lots of water where they feed on frogs and toads.


Left: Buff striped keelback | irfanazam / Shutterstock & Right: Coiled up buff striped keelback | Pratimaan / Shutterstock
55 – Common watersnake | Nerodia sipedon
The common watersnake also feeds on amphibians along with small birds and mammals, which they hunt at the water’s edge. This snake is ovoviviparous, meaning that it gives birth to live offspring rather than laying eggs.

56 – Diamondback water snake | Nerodia rhombifer
The diamondback water snake gets its name from the roughly diamond-shaped black spots that are present along its body and also, coincidentally, has a diamond-shaped head. This harmless species is often mistaken for the highly venomous cottonmouth.


Left: Diamondback water snakes | Laurie L Snidow / Shutterstock & Right: Diamondback water snake that is flattening its head in a defensive posture | Michael Benard / Shutterstock
Subfamily: Dipsadinae
Dipsadinae is a family of snakes containing 700 species that are present throughout the Americas. The various genera include snail-eaters, hognose snakes and a group of snakes that mimic various members of the venomous coral snake and viper families.
57 – Western worm snake | Carphophis vermis
The western worm snake has a very unique colouration, with a black or purple back and a light pink belly. They are very small with adults rarely surpassing 28 cm or 11 inches and their diet consists almost entirely of earthworms.


Left: Western worm snake in a knot! | Matt Jeppson / Shutterstock & Right: Western worm snake | Matt Jeppson / Shutterstock
58 – Ring-necked snake | Diadophis punctatus
The ring-necked snake is around the same size as the western worm snake and, like their pink-bellied cousins, exhibit a darker back and colourful belly, this time with a spectacular combination of orange and red.

59 – Catesby’s snail-eater | Dipsas catesbyi
The Catesby’s snail-eater is the first of two snakes that we’ll look at who prey upon arboreal land snails and slugs. This particular species lives in tropical forests, lowland areas and mountainous regions at altitudes of up to 1,500 meters or just under 5,000 feet.


Left: Catesby’s snail-eater portrait | Patrick K. Campbell / Shutterstock & Right: Catesby’s snail-eater | Patrick K. Campbell / Shutterstock
60 – Neo-tropical snail-eater | Dipsas indica
The neo-tropical snail-eater lives in South America alongside the Catesby’s snail-eater and uses its slender jaw to pry snails from their shells. There are two known subspecies both of which are fully arboreal.

61 – False coral snake | Oxyrhopus guibei
The false coral snake is one of many species of snake that have evolved to display the colouration of the highly venomous coral snake, a defence known as Batesian mimicry, where a harmless species mimics the appearance of a dangerous species.


Left: False coral snake | Tacio Philip Sansonovski / Shutterstock & Right: Portrait of a false coral snake | Tacio Philip Sansonovski / Shutterstock
62 – Tschudi’s false coral snake | Oxyrhopus melanogenys
The Tschudi’s false coral snake has two highly distinct subspecies. The first has black and red scales with black and white stripes. The second is known as the Black-Headed Calico Snake and is almost entirely black in colour with yellow stripes.

63 – Mud snake | Farancia abacura
The mud snake is almost entirely aquatic; it is usually found on the edge of swamps and streams where it preys on salamanders and other amphibians. They are found throughout much of the southeastern United Stakes.


Left: Eastern mud snake | Nathan A Shepard / Shutterstock & Right: Western mud snake | Ryan M. Bolton / Shutterstock
64 – Western hog-nosed snake | Heterodon nasicus
The Western hognose snake is one of two hog-nosed snakes we’ll cover that have upturned snouts, which they use for digging in the soil. This particular species has developed a resistance to the toxicity of toads, its primary prey.
