Indochinese Rat Snake – Non Venomous – Not Dangerous

Indochinese Rat Snake - grey, from Thailand - Ptyas korros
Ptyas korros - Non Venomous - Not Dangerous

Ptyas korros (Indo-Chinese Rat Snake)

Thais say: (ngoo sing baan)

Length: Adults are just over 1 meter.

Range: All over Thailand and most of Asia including: Burma (Myanmar), Cambodia, China, Hong Kong, India, Bangladesh, Indonesia, Laos, Taiwan, Thailand, Vietnam, Western Malaysia, and Singapore.

Habitat: Anywhere rats exist in abundance. They aren’t found on hills or in mountains, usually just the low-lying areas and where people and garbage are.

Active Time? Diurnal – active during daylight hours.

Food: Rats and other rodents, frogs and lizards. Much prefer rats. These are primarily rodent eaters and they vary little from their diet because there are usually plenty of rats available.

Defensive Behavior: Will flee very quickly if given the chance. If agitated, rat snakes bite quickly.

Venom Toxicity: No venom that is harmful to humans.

Offspring:

Notes: These are very common snakes, and are seen a lot because they prefer to be active during the daylight hours. They have very large eyes, which would make one think they can see well at night as well. These snakes can be held without striking (see video below).

Ptyas korros can be silver, grey, or brown – orange looking in color. Scales on the posterior part of the body and on the tail often yellow and edged with black. Underbelly is light yellow. Juvenile Indochinese rat snakes have a transverse series of round whitish spots or narrow yellow transverse bars.

Blood Python – Non Venomous – Not Dangerous

Blood Python from Southern Thailand - Python brongersmai
Blood Python from Southern Thailand rubber plantation.

Blood Python (Python brongersmai)

Thais say: (ngoo lahm pad ped)

Length: Average length is less than 2.5 meters max. Usually smaller than 2 meters. the one pictured here is 1.7 meters. Adult Blood Pythons typically are 137-182 cm (4.5-6 feet) long. Females are slightly longer than males. These snakes weigh 5-9 kilograms (12-20 lb).

Range: In Thailand only on the island of Phuket and in the far south from Krabi province and southward. The pictured Blood python came from a rubber plantation near Tub Kaak, Thailand in province of Krabi. Found on the Malay Peninsula.

Habitat: Flat land & marshy forests. Blood pythons prefer to live near water. They are often found on rubber plantations, as this one was. They typically hide under leaves and brush, or you can find them in the water. These snakes don’t go far when hunting, instead they lay still waiting for rodents or other mammals to walk by.

Active Time? Nocturnal – active at night.

Food: Rats, mice, chickens.

Defensive Behavior: A short powerful strike from the s-position. As mentioned, they can easily twist out of a snake handler’s grip.

Venom Toxicity: No venom. Little danger. These pythons bite with provocation, but they have a very short strike. Though their strike is short – they pack a powerful bite.

Offspring: Oviparous, with up to 30 eggs being laid at a time. After the eggs are laid the female mother coils around the eggs and vibrates, or shivers, to produce heat (88 to 90 degrees F) which the eggs need to develop. She lays 12-30 large eggs 60-70 days after mating in the first couple months of the calendar year. The eggs are 14-16 cm long and weigh about one-hundred grams each. Young Blood Pythons have same coloring as adults and are 30-40cm at birth. First shed is 2-3 months. Blood pythons can reproduce at between 1.5 and 4 years. Breeding can be started by cutting down the daytime light to 8 – 10 hours and setting night temperature to the mid-70’s. Bring the female to the male’s cage. Misting the snakes with water can facilitate breeding. Female Blood Pythons typically shed 14-20+ days after ovulation; eggs are typically laid within 30 days of post-ovulation shed.

Blood Pythons may live 25 years in captivity.

Notes: We caught another wild blood python on a rubber plantation just like this one. When catching this species one must be sure about the grip from the time grabbed because as short as it is, it is full of muscle. Though this snake appears fat, it is muscle. It is exceptionally strong when pulling out of a hold.

This snake can change the color of it’s head from dark to light gray.

These snakes can have a temper if caught in the wild. They can settle down with daily handling and stroking. Babies born in captivity are usually more calm than adults. Eventually holding them is a possibility. The Thai-Malaysian Blood Pythons bite more quickly than do the Indonesian variety.

The skin of these snakes is highly prized and they are hunted because of it. Their numbers are shrinking because they are killed for their meat and skins. Over 60,000 blood pythons and short-tailed python skins are taken each year.

Substrate: Best? Newspaper. Cover the bottom of the cage with a thick pile of newspaper and crumple up some loose balls so the snake can hide under it.

Brown Kukri Snake – Non Venomous – Not Dangerous

Kukri Snake in Thailand - non venomous, but biting snake found all over Thailand
Kukri Snake - Non Venomous - Not Dangerous

Oligodon purpurascens (Brown Kukri Snake)

Thais say: (ngoo kut )

Length: average just under 1 meter (about 37 inches)

Range: All over Thailand. Brown Kukri snakes were once thought to be native to only the southernmost Thailand provinces, however J. Bulian has found one in Pattaya and there have been others discovered farther in the northeast. Assume the Brown Kukri’s habitat is all over Thailand.

Habitat: These snakes prefer life in the forest and can be found at great elevations – about 1 mile high (1,600 meters). I have received numerous requests to identify this snake from readers who found them close to or inside their homes as well. The habitat is wide and varied for this species. Regardless where they are found, they enjoy living under brush, wood, rocks, and thick flora.

Active Time? Nocturnal, active at night and in the early morning as the sun rises.

Food: Frogs, lizards.

Defensive Behavior: If the brown kukris are bothered enough they will roll their body to the side and lift up their tail – perhaps to present it as a place to attack – leaving the mouth free to strike when the aggressor does go for the tail.

Venom Toxicity: No venom.

Offspring: Lay 6-12 eggs. A reader reported his snake had 8 eggs the first time and 10 the next. Eggs hatched after 60 days, incubated at 29 degrees C.

Notes: Though this snake is not venomous, it is keen to bite and can inflict deep wounds due to it’s large, curved teeth and strong bite. Michael Cota, researcher, says, “Appears that it might be an evolutionary link on the way to being venomous, since it is the only snake that I can think of that has “fangs” (enlarged pair of teeth), but no venom delivery system or ducts to the teeth. They are not dangerous, but will give you quite a bloody bite that takes a long time to heal. What makes them so difficult is that their head is not distinct; therefore, it is extremely difficult to grab behind the head and keep proper control of it.  It maneuvers it head around on your grip and then uses teeth to bite – slash.”

You’ll need a tetatus shot if you are bitten, as with all snakes as a precaution.

Kukris are common and you might see one in Thailand if you live here.
