King cobras are apex predators, meaning that they are at the top of their food chain. They feed primarily on other snakes, including other venomous species like cobras and kraits. They are also known to eat small mammals, birds, and reptiles, and can consume prey that is larger than their own body size.

The effects of king cobra venom can vary depending on the amount of venom injected and the location of the bite. Common symptoms of king cobra envenomation include severe pain at the site of the bite, swelling, blistering, nausea, vomiting, and dizziness.
