Physical Characteristics
Size and Appearance
The king cobra is the largest venomous snake in the world, reaching lengths of up to 18 feet (5.5 meters) [1]. It has a distinctive appearance, with olive-green skin and black and white bands that converge towards its head. The head is covered by 15 drab-colored and black-edged shields, giving it a unique and intimidating appearance.
Juvenile king cobras are smaller and black, with yellow or beige throats [1]. As they mature, their coloration changes to a more subdued, olive-green hue. The back is typically highlighted by yellowish or whitish crossbars or chevrons, and the underside may display a single color that may or may not be ornamented with bars.
Venom and Fangs
The king cobra’s venom is highly toxic, and a single bite can deliver enough venom to kill an elephant [2]. The venom is a complex mixture of enzymes, peptides, and proteins that can cause a range of symptoms, including paralysis, respiratory failure, and cardiac arrest.
The king cobra’s fangs are longer and more potent than those of any other venomous snake. They can grow up to 0.4 inches (1 cm) in length, and are capable of delivering a large amount of venom with a single bite. When not in use, the fangs are folded back against the roof of the mouth, and are replaced periodically throughout the snake’s life.
In conclusion, the king cobra’s physical characteristics, including its size, appearance, venom, and fangs, make it a formidable predator and a fascinating species to study.

Preferred Habitats
King cobras are well-adapted to a wide variety of habitats, from tropical forests to grasslands. They prefer dense forests, swamps, and bamboo thickets, where they can find cover and easy access to their favorite prey, which is other snakes. According to Reptile Training, vegetation offers these snakes with cover and easy access to their favorite prey, which is why they favor it.
King cobras have also been spotted as far below sea level as 2,000 meters above it, indicating their adaptability to different altitudes. However, they are not commonly found in urban areas or agricultural land.

According to National Geographic, the king cobra’s venom is strong enough to kill an elephant. They also feed on lizards, rodents, and birds. King cobras are active hunters and may consume prey that is larger than themselves. They are known to use their venom to immobilize their prey before swallowing it whole.
Reproduction and Lifespan
King cobras reproduce sexually and are oviparous, meaning they lay eggs. Females lay between 20 to 40 eggs in a clutch and incubate them for around 70 days. The hatchlings are independent from birth and are venomous. King cobras can live up to 20 years in the wild, according to National Geographic.
Conservation Status
The king cobra is classified as a vulnerable species by the IUCN Red List due to habitat loss and poaching for their skin, meat, and use in traditional medicine. They are also killed by humans out of fear and misunderstanding. The king cobra plays an important role in the ecosystem as a predator and helps control the population of other snakes. Conservation efforts are underway to protect the king cobra and its habitat, including the establishment of protected areas and education programs to raise awareness about the importance of this species.
