The tentacled snake is easily recognizable from its two prong-like scaly appendages or tentacles at the top of its head, giving it its name. Endemic to Southeast Asia, these snakes have venomous fangs positioned at the back of the mouth that they use while preying upon fish that they mainly consume. However, they generally do not harm humans.

Diet
The diet of the tentacled snake consists mainly of fish but has even been observed consuming frogs and crabs.
Lifespan
It lives for approximately 14 years.
Behavior
These snakes are aquatic, spending most of their time in water. They are noted to stay underwater for about 30 minutes at a stretch without moving to the surface for air.
They rarely come to land, except sometimes at night and during the dry season, buring themselves in the mud till the time it rains again.
Being nocturnal, the tentacled snake mostly hunts at night. They lie in wait in weeds, motionless and curved in a distinctive “J” shape, ambushing fish that pass them.
It displays several gestures while capturing its prey like retracting its eyes into its head.
The distinct tentacles on the top of the snake’s head play a vital role in their perception and feeding habits, alerting them to nearby prey. In fact, the nerves present in those tentacles provide information to the part of the snake’s brain that receives optic signals, giving it both visual and sensory output.
They have muscles in their neck area that help them make a sudden rippling movement the moment they sense their prey. The fish reflexively move in reaction to the sudden movements, trying to swim away, but end up getting tricked towards the waiting jaws of the snake.
Tentacled snakes use their prehensile tail to anchor themselves underwater, as they position their body upside-down in a J-like posture.
Their coloring and patterns help them camouflage with their surroundings.
Mating and Reproduction
They are viviparous, giving birth to live young underwater. Around 10 of them are born at a time.

Life Cycle
The newborn snakes are fully developed and become independent from birth. They develop natural instincts for hunting and anchoring on tree branches using their tail. The juveniles roughly grow twice their size in two months.
Conservation Status
The IUCN lists the tentacled snake as “LC” or “Least Concern”.
Interesting Facts
