Naja kaouthia, the monocled cobra is one of Thailand’s most deadly snakes – with highly toxic (neurotoxic + cytotoxic) venom. One bite on your toe from one that jumps out of your outdoor refrigerator can kill you. I just wrote a story about that on ThaiPulse.com/blog/. Monocled cobras seem to be everywhere in Thailand. I had a friend that found them in his kitchen often. I’ve seen them crossing the road (see video below), and there was a family of these cobras living under the office of my wife’s workplace – with many 18″ baby cobras.
Currently I have 2 baby monocled cobras and even at 12-15 inches – they are fierce. One snake handler described monocled cobras as “spastic” – and I have to agree.
If you are bit by any cobra – get to the hospital as fast as you can. Monocled cobra venom is more toxic than kraits, and much more toxic than the King Cobra venom. Even if the bite is a very small one – get to the hospital immediately. All it takes is a drop of venom to hit your blood stream for chaos to ensue.
(Thailand Monocled Cobra)
Appearance: Monocled cobras are easily identified by looking at the back of the hood – there is a monocle – or – eye type shape there. They are light brown to dark grey. The two I have now, and the two I had before were almost black.
Thais say: Ngoo how hom, Ngoo how mo (long o sound)
Length: Typical maximum length about 1.5 meters. Recently I saw one in a mangrove forest that was 2 meters or larger. They can get up to 2.2 meters – about 7.5 feet long.
Range: All over Thailand and most of southeast Asia.
Notes: Neuro toxic venom affecting nerves, brain, and causing death very quickly without treatment. They are very fast strikers. The baby monocled cobras are every bit as deadly. Please be CAREFUL!
Habitat: Both flat and hilly regions. I’ve seen them on hills, but usually near people – under houses and in places rats and frogs are likely to be found. In the mornings they can be in trees and bushes – trying to get some sun to warm up. They love to hide under leaves, wood, anything really. Lifespan is around 30 years.
Active Time? The snake is mainly nocturnal – active at night, but I’ve seen plenty of monocled cobras active during the daytime. In fact, in Thailand – I’ve only seen one active at night – the rest – dozens, active during daytime.
Food: Rodents, lizards, frogs, birds, eggs, other snakes.
Defensive Behavior: Lift head off ground and flatten out neck. The hood flares quite wide compared to the width of the body – versus that of the king cobras that don’t flare out that widely.
Venom Toxicity: Very toxic, deadly. Even a small bite can kill you. See “neurotoxic and cytotoxic venoms” (link).
Offspring: Lays 25-40 eggs. Young are fully prepared to envenomate as they hatch. Mating takes place after the rainy season stops. Eggs incubate about 2 months. Eggs hatch between April-June. Hatchlings are between 8 and 12 inches at birth.
Species: Naja kaouthia
Classified by: Lesson, 1841
