Cobra is the common name used to refer to a group of venomous snakes known as elapids, most of which belong to the genus Naja. All cobras are venomous and most have the ability to produce a hood when threatened. Here we are talking about the 10 most poisonous cobras as a list. The LD50 value of the venom of these snakes is indicated next to their names in parentheses. LD50 stands for lethal dose. The lower the LD50 value, the stronger the poison.
10. Equatorial Spitting Cobra (0.60 Mg/Kg)
The equatorial spitting cobra is a Southeast Asian species found in Thailand, Malaysia, the Philippines, Brunei, Indonesia, and Singapore. These snakes live in primary and secondary forests at altitudes of up to 4,900 feet. Some cobras also live near human settlements. The equatorial spitting cobra feeds mainly on rodents, but occasionally also feeds on other snakes, small mammals, and lizards. The equatorial spitting cobra is one of the most venomous cobras in the world. When threatened, they easily spit venom or bite. The venom of this cobra contains neurotoxins, cytotoxins and cardiotoxins that, if left untreated, can lead to the death of the victim.
9. Monocled Cobra (0.47 Mg Per Kg)
The monocled cobra is common in Southeast and South Asia. These cobras can adapt to a wide variety of habitats. One-eyed cobras are terrestrial snakes that feed on small mammals, snakes, amphibians and other reptiles. Snakes prepare to attack to defend themselves when threatened. The one-eyed cobra is highly venomous and consists of neurotoxins, cardiotoxins, and myotoxins.
8. Cape Cobra (0.37 Mg Per Kg)
The Cape cobra lives in a wide variety of habitats such as savanna, scrub, desert and semi-desert areas. It is a cobra native to South Africa. The snake has a wide prey base and hunts during the day.

The venom has both neurotoxic and cytotoxic components and can result in death if not treated promptly.
7. Indian Cobra (0.29 Mg Per Kg)
One of the most venomous snakes living in India, the Indian cobra is a member of the “big four”, four species of snakes responsible for most human snake bites in India. However, the Indian cobra is highly revered by Hindus and is even worshiped during the Hindu festival of Nag Panchami. The snake is found in both dense and open forests, rocky terrains, wetlands, crop fields and even human settlements. The bite of the Indian cobra delivers a powerful venom with both neurotoxic and cytotoxic components. The venom can cause paralysis and death if left untreated.
6. Chinese Cobra (0.28 Mg Per Kg)
The Chinese cobra is a venomous elapid that lives in Southern China. Many cases of snake bites related to this snake have been recorded in China and neighboring countries. The Chinese cobra lives in grasslands, mangroves, woodlands, and shrublands within its range. The species is also found at altitudes ranging from plains to as high as 6,600 feet. The snake has a large prey base that includes rodents, amphibians, smaller reptiles and birds. The Chinese cobra can be extremely aggressive when confronted and has the potential to attack if threatened. Neurotoxins and cytotoxins are the main components of Chinese cobra venom. A strong bite can inject enough venom to cause death in an adult human.
5. Indochina Spitting Cobra (0.25 Mg Per Kg)
The Indochinese spitting cobra is one of the most venomous cobra species found in Southeast Asia, including Laos, Vietnam, Cambodia, and Thailand. Snakes live in a wide variety of habitats, including woodlands, plains, and hills. The Indochinese spitting cobra exhibits highly variable behavior at different times of the day. It is shy during the day and immediately seeks shelter when threatened. However, if the snake is threatened at night, it will most likely attack. The snake first spits venom on its victim and, if further threatened, bites the victim. The venom of this spitting cobra is a potent combination of potent neurotoxin and cytotoxin. After the bite, untreated adult humans can die from muscle paralysis and suffocation.
4. Forest Cobra (0,225 Mg/Kg)
The forest cobra is an elapid that lives in Africa, especially in the western and central parts of the continent. Despite its name, the cobra can live in a wide variety of environments, including moist savanna habitats, lowland forests, and drier ecoregions. The diet of the forest cobra includes insects, small mammals and reptiles. The forest cobra is a very dangerous species. He is always on high alert and exhibits a nervous behavior. The bite of the forest cobra is life-threatening in nature due to the potent neurotoxic nature of the bite. Because the snake injects a significant amount of venom, death by poisoning can occur within 30 to 120 minutes.
3. Samar Cobra (0.21 Mg/Kg)
The Samar cobra is a highly venomous cobra native to the Mindanao and Visayas island groups of the Philippines. The habitat of this species ranges from tropical plains to mountain forests. The snake feeds mainly on rodents, and less often on reptiles and frogs. The Samar cobra produces a deadly neurotoxic venom that also has cytotoxic properties. The venomous bites of this cobra trigger extensive tissue necrosis and death from respiratory failure. The cobra is known for its nervous behavior and sprays venom when threatened. If the venom gets into the victim’s eyes, it can cause permanent blindness if not expelled in a timely manner.
2. Philippine Cobra (0.14 Mg Per Kg)
The Philippine cobra is a highly venomous elapid native to the northern parts of the Philippines.
