The tentacled snake is named for the two short tentacles which are present on the front of their head. The purpose of these has not been established. They may be used for camouflage or to sense prey.
These snakes feed almost exclusively on fish which are captured and subdued using a venom which is specifically adapted for this prey.
Females give birth to live young with a standard clutch including 10 individuals.
They are threatened through capture for food and persecution due to the perception that this species is a threat.
Read on to learn more about these radical reptiles.
Appearance
What does the tentacled snake look like?
Tentacled snakes are named for the two short tentacles which extend from their snout. They are the only species of snake equipped with these tentacles.
Their head is small but noticeably distinct from the neck.
These reptiles are covered by scales which are colored dark gray, brown or tan. Their scales are keeled. Individuals come in two varieties, striped or blotched. Black bars may also be present on some individuals.
An average tentacled snake will measure 0.7-1m (2.3-3.3ft) long.
Diet
What does the tentacled snake eat?
These animals are carnivores which will feed on animals such as fish and amphibians.
Hunting occurs in the water where they will lie in wait hidden by weeds and waiting for prey to pass them by. Their method of hunting is unique. They will hold their body in a rigid position with the tail anchoring them underwater. As prey approaches they will ripple their neck muscles and the fish flees sending it towards the snakes mouth.
Once prey does pass them by they will strike it rapidly and then wrap around it before constricting it to death. These animals are equipped with small fangs and a mild venom. It is most effective on the fish which they feed on.

No studies have been undertaken in to the population size of the tentacled snake.
Individuals are taken to supply the food trade. Some are also captured to feed crocodiles at farms. Some are also subject to by-catch within fishing activities.
In some areas across their range this species is persecuted due to a belief that they are dangerously venomous.
