The king cobra eats mostly other snakes. That is where its scientific name, Ophiophagus hannah, comes from: “snake-eater.” Wild king cobras go after rat snakes, other cobras, kraits and even small pythons, and they will take monitor lizards when snakes are scarce.
What King Cobras Eat in the Wild
The king cobra is the longest venomous snake in the world, reaching about 10 to 13 feet in most cases and sometimes more. It lives in forests and wetter habitats across India, Southeast Asia and southern China. Its diet is narrow compared with most snakes.
- Other snakes: the main food. Rat snakes are a favorite, and king cobras also eat cobras, kraits, keelbacks and young pythons.
- Monitor lizards: taken now and then, especially where snakes are hard to find.
- Small mammals and birds: reported occasionally, but they are not a regular part of the diet.
A king cobra tracks prey mostly by scent, flicking its tongue to follow a trail. It bites, holds on while the neurotoxic venom takes effect, and then swallows the prey whole, head first. A large meal can keep an adult going for weeks, and sometimes longer, before it hunts again.
How a King Cobra Eats a Snake Bigger Than Its Head
Like all snakes, the king cobra has jaw bones that are loosely linked, so each side of the mouth can “walk” over the prey one side at a time. The snake does not chew. It works the meal down its throat and digests it slowly. This is why one good meal lasts so long.
King Cobras in Captivity
King cobras are not pets. They are dangerous, they need very large and secure enclosures, and keeping one is illegal or tightly regulated in many places. Zoos and licensed reptile facilities do feed them in captivity, and some animals can be trained to accept dead rodents or other prepared food. Because wild king cobras depend on snakes, this switch does not always work, and it should only be handled by trained keepers.
If you are looking for a snake that is good for home care, a species such as a ball python or a rat snake is a far better fit.
Staying Safe Around King Cobras
King cobras are usually shy and will leave if they can. When cornered, an adult raises the front third of its body, spreads a narrow hood and gives a low hiss that sounds more like a growl. If you see this, back away slowly and give it room. A bite is a medical emergency: get to a hospital right away. Do not cut the wound, suck out venom or wait to see what happens.
Why the King Cobra Is at Risk
The IUCN lists the king cobra as Vulnerable. Forest loss, farmland expansion and hunting are shrinking its habitat. Because it eats other snakes, it also helps keep other snake populations in balance.
Bottom Line
The king cobra is a snake specialist: other snakes make up most of its diet, with the occasional lizard. It is not a pet, and the right way to enjoy one is from a distance or at an accredited zoo. To learn how other big snakes feed, see what anacondas eat or what black mambas eat.
Venomous snake bites need emergency care. For any pet reptile health question, check with an experienced reptile veterinarian.
