Though they tend to keep to themselves, threatened, they turn extremely deadly. Venom in certain cobras has grown so strong that a bite will kill or immobilise the victim, destroy internal organs, and kill within less than sixty minutes. This article takes an in-depth look at the five most lethal cobras, their unique characteristics, native habitats, and how lethal their venom is.
Deadly cobras known for their strong venom
King cobra
The King Cobra (Ophiophagus hannah) is not just the world's longest venomous snake—it's among the deadliest.
Growing up to 18 feet in length, the species occurs in India, Southeast Asia, and the Philippines.
What makes it so deadly:
The King Cobra bites with an enormous amount of neurotoxic venom in one bite—enough to kill a human being within 30 minutes or kill a full-grown elephant. The venom acts on the nervous system, which leads to respiratory collapse.
Though as large and menacing as they are, King Cobras are essentially timid.
They prefer to retreat when provoked but will elevate its body, flare its hood, and audibly hiss protest before they attack when cornered.
Forest cobra
As native to West and Central Africa, the Forest Cobra (Naja melanoleuca) is the biggest of all the real cobras, the adult tending to grow over 10 feet in length. Aggression, speed, and lethality: Forest Cobra is extremely aggressive and fast-moving. It is reputed to stand firm and bite if provoked.

Its venom is extremely neurotoxic, quickly striking at the victim's respiratory system and causing paralysis if not promptly treated.
What is particularly menacing about the snake is its boldness—unlike more timid species, it may actively hunt a threat over brief distances.
Philippine cobra
The Philippine Cobra (Naja philippinensis) is among the most poisonous spitting cobras in the world. Found in the northern regions of the Philippines, this cobra is extensively feared for its accuracy in spitting venom and the rapidity with which its toxins take effect.
This cobra possesses a precise venom range of 10 feet to directly hit the eyes of a menacing beholder. The venom is so potent that it can cause respiratory paralysis and death within minutes since it was envenomed.
It also causes death and paralysis by merely touching the eyes with venom, without even biting.
Because of its aggressive defense tactics and quick-working venom, the Philippine Cobra is one of the most dangerous snakes in Southeast Asia.
Indian cobra
Indian Cobra (Naja naja), often employed for religious and cultural symbolism in India, is revered yet dreaded. Prevalent throughout the Indian subcontinent, the cobra is part of the "big four" that causes the majority of snakebite deaths in India. The Indian Cobra is found in inhabited villages and cultivated fields and thus has opportunities for frequent human contact. The venom is neurotoxic and leads to slow paralysis and, if left untreated, respiratory failure.
There are thousands of bites of this species every year, thus constituting a major public health problem.
Though divine in Hindu legend, Indian Cobra venom remains an actual threat, particularly in countryside settings with limited access to antivenom.
Cape cobra
The Cape Cobra (Naja nivea) inhabits South Africa's dry, desert regions, Botswana, and Namibia. The Cape Cobra is known for its ferocity and extremely virulent venom.
The venom of this snake is a powerful neurotoxin which can be deadly for a human being within one to two hours if medical care is not received in time. The snake is also highly adaptable and is found in homes, barns, and piles of wood, and this raises the likelihood of false encounters.
The Cape Cobra, as opposed to the majority of other species, does not give sufficient warning before it attacks and is hence very dangerous to unsuspecting visitors.
All the five species of cobras have deadly venom and fierce behaviour patterns but hardly ever attack unless cornered or provoked. Public knowledge, immediate accessibility of healthcare, and availability of antivenom are therefore the prime considerations in preventing loss of life where these snakes are found.
