When they feel threatened cobras, known in Thai as ngu hao, will expand their hood and raise the anterior third part of their body, hiss and strike. It is this hissing sound that gives them their Thai name ngu hao, which means  ‘barking snake’.

VENOMOUS! This snake has a strong neurotoxic venom and its bite is deadly! It can be fatal in less than an hour. Envenoming may cause local pain, swelling, blistering, necrosis, flaccid paralysis and respiratory failure. All cases should be treated as urgent and potentially lethal.
