Homalopsis buccata (Puff-faced Water Snake)

Thai – (ngu hua galog, ngu leuam ao)

Size – Average length around 70 cm. Maximum about 120 centimeters. The young are very thin – like a pencil. The adults are thick – like a forearm or even a human leg.

Description – Triangular head distinct from neck. Color varies quite a bit. Brown with incomplete orange bands on the dorsum and laterals, or brown with beige bands, or black with grey bands. Many variations. Sometimes the snake appears quite orange.

Range – All over Thailand and almost always beside or in water: Pools, streams, rivers, puddles, lakes. They are not found on hills or mountains.

Food – Prey includes fish, frogs, and tadpoles primarily.

Behavior – The water snake Homalopsis buccata lives in fresh and salty mixed with fresh – brackish water. These snakes live in and near any body of water – natural or man-made. Puff-Faced Watersnakes are found almost always in the water or on the bank. Small holes in the bank are often home for these snakes.  This snake is primarily active at night, but I have found a few during the daytime.

Young – Born alive without eggs. Coloration – orange and black bands.

Danger – I’ve found dozens of these snakes and they are typically strong and active biters. They can strike like a viper – backward and vertically. I’ve been bitten in the finger by a 70 cm. long snake when I was 5 inches away from the head, coming from behind to grab the neck. With the bright headlamp in his eyes, I don’t know how he could have possibly seen my hand coming. It wasn’t a glancing strike, he bit and held on for a couple of minutes. I have heard others say these snakes don’t tend to bite. Maybe they are talking about in their experiences in the pet-trade.

Range – Bangladesh; Myanmar, Cambodia; Thailand; Vietnam; Indonesia; Laos; Malaysia; Singapore; India; Nepal; Pulau Bangka

Enhydris plumbea (Plumbeous Water Snake, and Rice Paddy Snake

Thais say: (ngoo bping)

Length: average length for these snakes is about 50cm (19 inches)

Range: The plumbeous water snake is found all over Thailand as well as nearly all of southeast Asia.

Habitat: Near or in water. Lakes, streams, rivers, puddles, marshes, any where water is.

Active Time? Diurnal – active in daylight mostly.

Food: Food is generally fish and frogs, though other opportunistic eating may take place.

Defensive Behavior: Typical s-shaped striking position. Not very mobile on land.

Venom Toxicity: Venomous. Not toxic enough venom to affect humans severely. No known cases of death due to bite from this species in the herpetological literature.

Offspring:

Notes: As you might have guessed, these snakes are most commonly found in the vast rice fields of Thailand. These are common snakes, we have found two of them recently – one in a small pond with many frogs. One at a resort with a stream and some shallow pools of water.

Jagor’s Water Snake – Venomous – Not Dangerous

Leave a comment

Thailand water snakes are close to or living in the water. You won’t likely see the Jagor’s water snake anywhere near your house or out in a Thailand park unless there is water there.

Thais say: (ngoo sy rung ly kwang)

Length: usually less than .5 meters (50cm, 19 inches)

Range: All over Thailand

Habitat: I have seen these Jagor’s water snakes in small pools of water at a city dump as well as a mountain stream. They are very dark and difficult to see.

Active Time? Night and daylight hours.

Food: Fish and frogs.

Defensive Behavior:

Venom Toxicity: There are no known cases of death from this snake. Probably the venom is not very strong for humans.

Tentacled Water Snake – Venomous – Not Dangerous

2 Comments

Erpeton tentaculum (Tentacle Snake, Fishing Snake)

[Page Updated: 28 November 2019]

Thais say: (ngoo kra deng)

Length: average snakes are up to 50-90 cm as adults.

Range: Central and southern Thailand only

Habitat: Tentacled water snakes are found in lakes, rice fields, streams, and other shallow water that is either moving or stagnant – especially that which is murky. It is found in all three types of water environments including salt, fresh, and brackish (combined) water. This snake waits patiently on the bottom and waits for something to wander by – whereupon it seizes it in it’s mouth. Amazingly the tentacled snake can stay underwater for 30 minutes on a breath.

During the dry season in Thailand – from January to April, the Erepton tentaculatus buries its body in mud to stay wet and cool, with its head out of the moud – of course. They do need oxygen to survive.

Active Time? When night is falling it is known to be more active.

Food: Fish. To lure the prey closer to provide the opportunity for a strike these tentacled snakes use their tentacles as lures – like tiny worms. When the fish come closer they strike. When striking their eyes are retracted and they aim for where the fish will be, not where it is. This is an amazing feat. In actuality, the snake is tricking the fish with a movement of its body – into fleeing. But, it knows exactly where it will go when it flees. A very unique snake.

Defensive Behavior: Bites when provoked, but not with normal handling.

Venom Toxicity: Weak venom that is not known to affect humans much. Not deadly. These are not biters, per se, and even when handled they are not known to bite much. The fangs are small, in the rear of the mouth, and the fangs are only partially grooved, not made for injecting large amounts of toxic venom. Their venom works well on fish they eat.

Offspring: Each year this water snake gives birth to a half to a dozen live young which are between 20 and 40 cm in length and about a pencil’s diameter in girth.

Notes: Because it spends it’s life buried in mud, or under the water looking for prey it is a rather difficult snake to catch. Recently on a herping trip in southern Thailand I believe a group of us saw one, but, when we reached in with the tongs to attempt to grab the snake, it had already darted.

These snakes are either lightly striped or have blotches. Their color is either hues of grey or brown.

Homalopsis buccata Almost Rips My Finger Off

OK, exaggerating a bit.

OK, a lot.

There is nothing quite like a bite from a snake, when you’re completely not expecting it. I’ve caught a number of these “Puff Faced Water Snakes” – Homalopsis buccata, and while one bit the tongs, none has ever attempted to strike at me. That changed the other night while on a herping trip with Courtney from North Carolina in the states.

I grabbed it fine the first time, and it death-rolled so fiercely I thought it was going to break it’s own neck. I let it go back on the ground by the pond I’d just picked it up at.

The flashlight was shining right in his face – and I was coming up on the approach from behind, but, in hindsight – a bit too much to the side, and he could still see my hand coming. He twisted and struck backward and sideways to grab my middle finger fiercely. I did the twitch, you know, where you jerk your arm in an exaggerated fashion, twirling the snake around like a circus baton, by the mouth on your finger – putting the teeth MUCH deeper than they were originally? Yeah, I did that.

He was NOT letting go, so I asked Courtney to gently put the snake hook point through the jaw between my finger and the joint. Eventually the top opened enough, and then I snuck the bottom finger out. No re-bite, which I was thankful for.

This was a juvenile, but these snakes have powerful jaws, and 26 teeth (I counted the puncture marks on my finger). I was bleeding good, and Courtney got a few pics. Will put one up when she sends me one.

Though a snake is not “known” to bite… do not take it for granted. Practice the same techniques as always to keep from getting bitten. Twenty-six teeth in your finger is not a good feeling… more importantly, you could break some of them in your finger – harming the snake.
