King Cobra – Hong Kong Wildlife | 眼鏡王蛇 – 香港野生動物

Every time I ask the boys, from young boys to teenagers to young men, “What’s your favorite snake?” I definitely hear King cobra more than any other snakes! Despite the fact that it doesn’t have the deadliest venom comparing to the Inland taipan, the King cobra still holds a special place in many boys’ hearts as “the most dangerous snake in the world”. It could even be prior to the hottest pop star or the coolest car because all those will become obsolete from time to time. But the realm of the King cobra just never gets dated.

Arguably the largest venomous snake

Some Gaboon vipers (even though obviously shorter) could be heavier than King cobras. So the King cobra is sometimes not considered the largest venomous snake (in weight), but it is undoubtedly the longest venomous snake in the world – commonly grow to over 10-12 feet, with the longest record over 19 feet. It is much longer than the second-longest venomous snake, the Black mamba, which generally won’t exceed 9 feet.

The King

Do we call the females Queen cobras, like queen bees? No. We also don’t call the young Prince cobras or Princess cobras. King is an honor to refer to its top danger level and its snake-eating habit.

O. hannah

Oh, Hannah! Hey, all the Hannahs out there! Did you know that you share the name with the King cobra? Ophiophagus hannah in Greek means arboreal snake-eater. The name was given by Danish naturalist Theodore Edward Cantor in 1836.


As its name suggests, the Kings are ophiophagous. They specialized in eating snakes. In Hong Kong, I’ve seen them preying on young Burmese pythons, Oriental ratsnakes, deadly Banded kraits and Many-banded kraits. Having snakes as the staple diet doesn’t mean the Kings will never ever eat anything else. Not common at all, but I’ve also seen them eating Water monitor lizards. In captivity, some Kings can be converted into chowing down rodents or birds. To make that happen it will require some tricks to confuse the Kings which will make things pretty messy. I ain’t gonna describe it here..

What? King cobra is not a cobra?

Even such a popular snake has its little secret that most people don’t know. Sorry to be a killjoy. The King cobra is not a cobra. True cobras are smaller and they are all in the genus Naja such as the Chinese cobra.

Different realms, different Kings

These in my photos are the Kings I encountered in SE Asia unofficially known as “Malaysian king cobras”. The King cobras in Hong Kong, unofficially known as “Chinese king cobras”, have much darker coloration from tan to almost black with indistinct yellow bands all over the body. The yellow bands start off bright yellow when young and fade into a pale color close to the body color when old. They are the same species though. No subspecies have been distinguished within the species. That is always only one recognized King.
