King Cobraキングコブラ

Ophiophagus hannahVU— Vulnerable

The king cobra is the world's longest venomous snake, native to forested hills across South and Southeast Asia. True to its scientific name Ophiophagus, meaning "snake-eater," it feeds almost exclusively on other snakes, including smaller members of its own species. It is the only snake known to build a nest for its eggs, with females fiercely guarding the clutch, and is classified as Vulnerable by the IUCN due to habitat loss and persecution.

FAQ

What does a king cobra eat?
Its diet is dominated by other snakes—including venomous species and even smaller king cobras—supplemented occasionally by lizards and small mammals. Source
How dangerous is king cobra venom?
A single bite can deliver more than 200 mg of neurotoxic venom, a quantity large enough that it is sometimes described as capable of killing an elephant, though human fatalities are less common than with some other cobra species due to lower encounter rates. Source
Is the king cobra the only snake that builds a nest?
Yes. It is the only known snake species that constructs an above-ground nest from leaf litter and vegetation, and the female stays to guard the eggs until they hatch. Source
