Vampire bats using a highly sensitive heat sensor near the nose and mouth to determine the presence of blood. David Julius of the University of California, San Francisco, United States, researching sensors that and quoted the website LiveScience, Wednesday (03/08/2011).
Vampire bats are sleeping target animals, like birds and mammals, even humans. Research has shown that bats have cells in the brain that are sensitive to sound a sleep breathing animal.
Heat sensor makes bats can distinguish skin that covers the body part containing fresh blood and warm with a hair area. They use sharp teeth to make the holes 5 millimeters square on the skin and suck the blood of animals without waking.
Bats use a receptor that is found in mammals, including humans, to feel the heat and spicy chili. However, bats receptors capable of detecting lower levels of heat, about 30 degrees Celsius, from a distance of 20 centimeters.
