With a body length between 200 and 540 centimeters, the King Cobra is the world's longest venomous snake. Its hood is longer and narrower than that of common cobras, and it also has pairs of prominent occipital scales on its head.

VENOMOUS! This snake is deadly, able to kill even water buffaloes and elephants. It has a strong postsynaptic neurotoxic and cardiotoxic venom and its bite likely causes severe envenoming with a high lethality potential. Without the administration of an antivenom envenomation can be fatal for humans in less than an hour. Whereas its bite does not cause significant injury at the bite site, it may cause muscle damage or bleeding, moderate to severe flaccid paralysis, and bradycardia. All cases should be treated as urgent and potentially lethal. Thailand Antivenom Code: SAsTRC03
