The venomous snakes of Hua Hin

King Cobra (Ophiophagus Hannah)
ngu jong aang

The king cobra averages at 3 to 4 m in length and typically weighs about 6 kg.

The venom of the king cobra consists primarily of neurotoxins, known as the haditoxin, with several other compounds.  Accordingly, large quantities of antivenom may be needed to reverse the progression of symptoms developed if bitten by a king cobra. The toxins affect the victim’s central nervous system, resulting in severe pain, blurred vision, vertigo, drowsiness, and eventually paralysis. If the envenomation is serious, it progresses to cardiovascular collapse, and the victim falls into a coma. Death soon follows due to respiratory failure. Bites from a king cobra may result in a rapid fatality which can be as early as 30 minutes after the envenomation.

Siamese Spitting Cobra (Naja siamensis)
ngu haow thong ponn phit

this species is medium in length, averaging between 0.9 to 1.2 m in length, though they can grow a bit longer to 1.5 m.
though not very aggressive in nature, these snakes can and will readily spit venom when they are cornered or threatened. They will also strike and bite.

Like other cobra species, this snake possess postsynaptic neurotoxic venom. The venom may also consist of cardiotoxins and cytotoxins.
It is very dangerous. His bite is potentially fatal, and he is able to spit venom possibly causing blindness;

 ngu haow Thai

The monocled cobra has an O-shaped, or monocellate hood pattern.
when threatened they will raise the anterior portions of their bodies, spread their hood, usually hiss loudly, and strike in an attempt to bite and defend themselves.

The major toxic components in cobra venoms are postsynaptic neurotoxins, which block the nerve transmission.
The monocled cobra causes the highest fatality due to snake venom poisoning in Thailand.

Malayan Krait (Bungarus candidus)
 ngu thap saming khlaa

The Malayan krait may attain a total length of 108 cm.

Dorsally, it has a pattern of 27-34 dark-brown, black, or bluish-black crossbands on the body and tail, which are narrowed and rounded on the sides. 

venom is neurotoxic and attacks the human nervous system, shutting it down. Coma, brain death, and suffocation due to paralysis of the muscles and nerves necessary for crucial functions like the diaphragm, and or heart, are frequent causes of death. Death results usually 12-24 hours after an envenomed bite that is not treated.

The major clinical effects caused by the venom of this species include vomiting, abdominal pain, diarrhea, dizziness, etc. Severe envenomation can lead to respiratory failure and death may occur due to suffocation. Few authenticated records of human beings having been bitten are available

Macrops Pit Viper (Trimeresurus macrops)
ngu khieow hang mai dtaa dtoo

It can be distinguished from other green pit vipers by the relatively large size of its eyes, which is especially noticeable in adult specimens, and to which the specific name, macrops, refers.
The venom of the Cryptelytrops (Trimeresurusmacrops mainly consists out of hemotoxin and pro/anticoagulants. Studied bite incidents showed clear effects on the fibrinolytic system and caused coagulation problems. Bites in the first stages cause redness, bleeding from the bite wound, irritation, swelling, pain, bruising, more pain, headache, nausea, stomach pain, and cramps resulting in diarrhea and vomiting. Long term effects can be tissue damage and even loss of (part of) a limb.
