FAMILY Viperidae (Vipers)

Rhinoceros ViperVery long venom fangs that need to be folded flat against the upper jaw when the mouth is closed. Venom is powerful and bites, while not always life-threatening, need rapid medical attention and antivenom may be required. Most snakes in this group are VIPERS.

Kenya has many kinds of Vipers, of all sizes. Generally they are heavy-bodied, with a narrow neck and a wide head and markings that give them superb camouflage. They lie in ambush for their prey and strike very rapidly when a suitable animal has come close enough to reach. They eat warm- blooded animals and birds, and sometimes toads. Because they lie hidden on the ground instead of running away as most other snakes do, Vipers are a danger to humans and livestock.

GENUS Bitis (True African Vipers)
Puff Adder Bitis arietans
 Bitis arietans Bitis arietans Bitis arietans
In Kenya the Puff Adder is considered the most dangerous snake we have – it is not aggressive but has a quick reaction and is more likely to come into contact with humans than most other deadly snakes.

The long fangs inject venom deep into the wound and severe tissue damage can result unless proper medical treatment is started at once. Antivenom is very important – the sooner it can be administered the less ‘aftercare’ will be required. Vipers have babies born alive (most other snakes lay eggs) and a large female might have nearly 100 babies.

Puff Adders cannot be tolerated near homes or where livestock is penned but out in the bush they are important in helping to maintain the balance of nature. They can eat animals up to the size of a young rabbit.
