The tentacled snake or tentacle snake (Erpeton tentaculatum) is a rear-fanged aquatic snake native to Southeast Asia. It is the only species of the genus Erpeton. The two tentacles on its snout are a unique feature among snakes.
The tentacled snake is a relatively small snake, averaging about 50 to 90 cm (20 to 35 in) in length. They are known to come in two color phases, striped or blotched, with both phases ranging from dark gray or brown to a light tan. It lives its entire life in murky water.
The tentacled snake is the only species of snake to possess twin "tentacles" on the front of its head, which have been shown to have mechanosensory function. Its diet consists solely of fish. Although it does have venomous fangs, the tentacled snake is not considered dangerous to humans. The fangs are small, only partially grooved, and positioned deep in the rear of the mouth. The venom is specific to the fish that the tentacled snake eats.

Rare
Under 5% of wildlife watchers report a Tentacled Snake sighting in Bangkok on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 29th most-seen of the 35 reptiles we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
July–August and December
In those months about 10% of wildlife watchers report a Tentacled Snake in Bangkok on a given day, against under 5% in January–June and September–November, the lowest months.
Only Bangkok, in our data
Bangkok is the only city on Wallace's Line with enough records to rate Tentacled Snake sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Homalopsidae
The closest relatives of the Tentacled Snake that you can see in Bangkok (family Homalopsidae, Mud Snakes) are Jack's Water Snake (about 10%) and Southeast Asian Bockadam (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Tentacled Snake is recorded against all the reptiles logged in Bangkok (10 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
