AFRICA: Boa Constrictors are one of the largest snakes in the world, along with the Reticulated Python and Anaconda. Boas are non-poisonous but just as deadly. Just as their name suggests, they will coil their bodies around their prey and with each breath of the prey they will squeeze their coils just a little tighter until the animal can no longer breathe. Their prey are consist of birds, lizards, frogs and small mammals. Larger Boas will even eat monkeys, pigs or deer.
Only just, researchers at Dickinson College, Carlise, in Pennsylvania, believe that constrictors kill by cutting off the blood supply, squeezing their prey until the animals’ circulatory system essentially short circuits and fails.
Scott Boback, a vertebrate ecologist at the US College who led the research, suggests that cutting off the preys’ blood supply is a much more efficient killing method for constrictors.
“The heart literally doesn’t have enough strength to push against the pressure,” said Mr Boback in an interview at National Geographic.
