Boa constrictor kills its prey with a strong and slowly winding. Then, when the snake is typical of the American continent took off the windings?
Knowledge during this time to mention it takes about 20 minutes to boa stop twisting. However, this assumption is contradicted by a recent study conducted by Scott Boback from Dickinson College, USA.
"The snake coiled boa stopped after the heart stops beating prey," said Boback, a biologist. According to Boback, convolute the process of prey is an activity that takes energy. Therefore, it is important for boa twisted prey with precise and accurate.
So, according to Boback, this snake just loosen entanglement when prey was unable to fight or flee. Boback conclusions obtained after he experimented with installing artificial heart that is inserted into the dead rats.
Artificial heart that beats are arranged in a certain time. Mice are also fitted with a coil winding boa is capable of measuring pressure.
Rat carcasses were thrown into a hungry boa cage. Did not wait long to grab and melilitnya boa. Yet convolute boa prey beyond the time previously thought. Cause, Boback arranged for the artificial heart was beating a dead rat in a long time.
Another case when he set the heart beating prey shorter. Boa convolute stop after 10 minutes. According to Boback, the ability to feel the heart beat of prey was obtained boa since birth.
Another interesting thing found in this study were wild boa set the power of entanglement in accordance with changes in heart rhythm prey. Wild boa usual hunt lizards were trained to adjust the power of entanglement.
"Boa feel the heartbeat of prey, but the setting turns the power gained through experience," he said.
Boback suspected snake skin extra-sensitive develops after these animals lost a leg in the process of evolution. The skin then becomes important senses in snakes so that they can sense the surrounding environment. *** [LIVESCIENCE | ANTON WILLIAM | KORAN TEMPO 3769]
