The king cobra (Ophiophagus hannah) is one of the most feared and deadly snakes in the world. This regal serpent, known for its size and potent venom, is capable of killing an elephant with a single bite. Found in forests and jungles across South and Southeast Asia, the king cobra is both a predator and a symbol of power in many cultures.
In this topic, we will explore the physical characteristics, venom potency, hunting behavior, and fascinating traits of this legendary snake.
Physical Characteristics of the King Cobra
1. Largest Venomous Snake in the World
The king cobra holds the title of the longest venomous snake on Earth, growing up to 18 feet (5.5 meters) long. Despite its size, it is extremely agile and can raise one-third of its body off the ground when threatened.
2. Distinctive Hood and Scales
Unlike other cobras, the king cobra has a narrower hood and distinct chevron markings on its body. Its scales are smooth, usually in shades of olive green, brown, or black, helping it blend into its surroundings.
3. Sharp Vision and Intelligence
This snake is known for its excellent eyesight and high intelligence compared to other reptiles. It can recognize handlers and adapt its hunting techniques, making it a formidable predator.
Why Is the King Cobra’s Venom So Deadly?
1. Neurotoxic Venom That Shuts Down the Body
The venom of a king cobra is highly neurotoxic, meaning it attacks the nervous system. When injected into a victim, it can cause:
- Paralysis
- Respiratory failure
- Cardiac arrest
2. Enough Venom to Kill an Elephant
A single bite from a king cobra can deliver up to 7 milliliters of venom, which is enough to kill 20 humans or even an elephant. Unlike other venomous snakes that deliver small amounts, the king cobra releases a large quantity of venom in each strike.
3. How Fast Does It Kill?
- If bitten, a human can die within 30 minutes if untreated.
- In larger animals like elephants, a bite to a vulnerable area (such as the trunk) can be fatal in a few hours.
Diet and Hunting Behavior
1. Eats Other Snakes
The king cobra’s scientific name, Ophiophagus, means “snake-eater.” Its diet consists mostly of other snakes, including:
- Pythons
- Rat snakes
- Other venomous cobras
2. Hunts Using Smell and Sight
Unlike vipers that rely on heat-sensing pits, the king cobra hunts primarily using its sense of smell and keen vision. It flicks its forked tongue to detect prey and can strike with incredible speed.
3. Non-Aggressive But Highly Defensive
Despite its deadly reputation, the king cobra is not naturally aggressive. It usually avoids humans but will defend itself fiercely if threatened. When confronted, it:
- Raises its body
- Spreads its hood
- Hisses loudly
