Top 6 Venomous and Deadly Snakes of India

Rate this post

For poisonous animals, India’s dark, deep woods provide suitable habitat. Giant snakes, scorpions, and venomous spiders find plenty of prey in these jungles. With 270 kinds of snakes, 60 of which are highly venomous, India is home to a plethora of lethal creatures, including the world’s deadliest snake, the king cobra.

The Indian or spectacled cobra, the common krait, Russell’s viper, and the saw-scaled viper are among the so-called great four snakes of India. In India, snake bites claim the lives of about 50,000 people each year. Check out this list of India’s top 6 most dangerous snakes.

Spectacled Cobra or Indian Cobra

Spectacled Cobra or Indian Cobra

Scientific Name : Naja naja
Venom Type: Neurotoxic
Max. Length: 7 Feet
Average Life: 9 Years
Locality: All Over India
Kill a Human: Withing 2 Hours (Without Antivenom )

The Nag, commonly known as the Indian or spectacled cobra, is an extremely poisonous snake found in India. Rodents, lizards, and frogs are among its favourite foods. In India, there are many different types of cobras, but this particular variety is responsible for most snake bites.

The colour (morph) and pattern of a Spectacled Cobra are heavily influenced by geographical location. This species might be grey, yellow, tan, brown, reddish, or black in colour. Many examples bear a hood mark with two circular motifs joined by a curving line, like glasses. This hood mark may be seen on the Spectacled Cobra’s hood.

.This species is easily distinguished by its large hood, which grows when threatened. If it is disturbed more, it hisses and attacks fiercely. An adult specimen can grow to be 1 to 1.5 metres (3.3 to 4.9 feet) long.

Throughout its geographical distribution in India, this species occupies a diverse range of environments. It inhabits deep woods, wide plains, agricultural areas, rocky terrain, and marshes.

The Spectacled Cobra is a skilled swimmer who is active both during the day and at night. Rodents, toads, frogs, birds, and snakes are among the prey base.

The Spectacled cobra is oviparous and deposits its eggs between April and July. The female cobra lays 10 to 30 eggs in termite mounds or abandoned rat tunnels. The female remains with the eggs for roughly 60 days until they hatch.

The hatchlings range in size from 20 to 30 centimetres (7.9 to 11.8 in). They have completely functional venom glands and are self-sufficient from birth.

Rat Snake (Ptyas mucosus), Banded Racer (Argyrogena fasciolata), and Indian smooth snake are all snakes that might be mistaken for the Cobra (Coronella brachyuran).

Nag () (Hindi, Oriya, Marathi, Urdu); Moorkan (Malayalam); NaguPamu (Telugu), NagaraHavu (Kannada), Naga Pambu or Nallapambu (/) are some common local names for the Spectacled Cobra (Tamil) Assamese “Phetigom” and Gokhra () (Bengali).

Common Krait or Indian Krait

Scientific Name : Bungarus Caerulus
Venom Type: Neurotoxin
Max. Length: 6.5 Feet
Average Life: 10-17 Years
Locality: Villages of India
Kill a Human: Within 45 Min. (Without Antivenom )
Snake Bite: Reach the nearest hospital immediately

The Indian Krait, also known as the Common Krait, is a venomous snake that may be found in the Indian Subcontinent’s jungles and towns. This species is the top member of India’s big four snake family and is responsible for the majority of snakebites on humans in the country.

Krait venom includes a high concentration of neurotoxins that can cause muscular paralysis, and its bite can be fatal. The common or Indian krait is found in the jungles and villages of the Indian subcontinental region. There are 12 species and 5 sub-species of krait snakes worldwide.

The Indian subcontinent is home to the Common krait, a very poisonous snake. It is one among the “big four” snake species that attack humans the most in Bangladesh and India. This snake is normally black or bluish-black in hue, with around 40 thin, white crossbars that may be unclear or nonexistent anteriorly.

Albino specimens can be discovered, although they are quite rare. In the young, the pattern is full and clearly defined, with obvious crossbars even anteriorly; in the elderly, the narrow white lines may be detected as a series of linked spots, with a notable spot on the vertebral region. A white preocular patch may be visible, as well as white upper lips and belly.

Russell’s Viper

Venom Type: Hemotoxin
Max. Length: 3.3 Feet
Average Life: 10-17 Years
Locality: Western Ghats
Look-Alike: Indian Rock Python, Common Sand Boa, Saw Scaled Viper
Kill a Human: Within 45 Min. (Without Antivenom )
Snake Bite: Reach the nearest hospital immediately

More people have been killed by Russell’s viper than by any other snake in India. This deadly snake, which may be found throughout the country, produces a sizzling noise before striking. Because it is nocturnal and can be discovered inside camping equipment or autos, it is quite deadly. The Russell’s viper is known locally as “Daboia” or “Koriwala.”

The poison it produces is a hemotoxin that can harm any animal’s central nervous system. Its bite can kill a human after internal bleeding, excruciating pain, and a brain haemorrhage. This dark brown or brownish-gray snake, with an average length of 4 feet, feeds on rodents, small birds, and lizards.

Saw-Scaled Viper

Saw-Scaled Viper

Scientific Name : Echis Carinatus
Venom Type: Hemotoxin
Max. Length: 2.6 Feet
Average Life: 23 Years
Kill a Human: NA
Snake Bite: Reach the nearest hospital immediately

The saw-scaled viper is distinguished by its larger-than-average eyes, a head that is wider than the neck, and a stocky body. It can be found in sand, rocky environments, soft soil, and scrubland. It eats lizards, frogs, and a variety of arthropods such as centipedes, big insects, and scorpions, among other things.

The saw-scaled viper is the smallest member of the big four groups of venomous vipers, earning it the nickname “little Indian viper.”

King Cobra

The King Cobra

Scientific Name: Ophiophagus Hannah
Venom Type: Neurotoxin
Max. Length: 12 Feet
Average Life: 20 Years
Average Weight: Upto 9 Kg.
Locality: Kerala

Snake Bite: Reach the nearest hospital immediately

The king cobra is the world’s longest venomous snake, with a length of up to 5.5 metres and the ability to elevate its head 2 metres above the ground. It’s a carnivorous snake that eats other snakes as well. The non-venomous rat snake, other cobras, kraits, and small pythons are among its favoured prey.

The deadly sting of the king cobra has resulted in a number of deaths in India, and it is regarded as one of the most dangerous snakes on the planet. Cobras do not need to bite to injure their prey; they may spew venom from their fangs across a 2-meter distance, blinding their victim and causing severe eye damage if not washed out immediately.

It lives in India’s dense jungles, chilly marshes, bamboo clusters, and rainforests. The Indian state of Kerala is home to the king cobra. With pale yellow cross bands, this enormous, powerful snake can be brown, olive green, or black.

Although there is an anti-serum for avoiding king cobra attacks, it is still one of India’s most dangerous creatures, capable of killing a person with a single bite.

Banded Krait

Banded Krait

Scientific Name: Bungarus Fasciatus
Venom Type:
Max. Length:
2.7 m
Average Life:
9 to 19 years

The Banded Krait is one of the biggest kraits snake species found in India’s diversified environment. It is easily identified by its characteristic cross bands of black-yellowish tint. Among Krait species, the Banded Sea Krait is the most venomous in the world and in India.

It feeds on coral reefs in India and is primarily found underwater. It is sometimes mistaken for eels. Its tail is sometimes misconstrued as its head by victims, which this snake exploits.

It is quite little yet extremely poisonous. Another distinguishing trait of this snake is that, although spending most of its time below, it would frequently come on land to sip fresh water.
