Mangrove snake

Boiga dendrophila

The mangrove snake is also called the gold-ringed cat snake and is the largest species of cat snake. Cat snakes belong to a group of venomous snakes called rear fanged snakes. In most venomous snakes the fangs are hollow and glands help to inject venom through the hollow fangs like a hypodermic syringe.

Rear fanged snakes’ fangs have grooves and the venom is released slowly as the snake chews its prey. The mangrove snake’s venom is quite weak. The longer the bite, the more toxic it will be. They can be confused with the deadly, venomous banded krait.

The Mangrove snake can be up to 240 centimetres long. It can be found in the zoo’s Reptile House.
