they love to look for their prey all the time
A vampire bats protects itself by biting the prey.
Vampire bats find their prey by using echolocation and by detecting infrared radiation. After locating prey, they bite it with their teeth and lick the blood with their tongues.
The Vampire Bats hunt for prey/food when it is completely dark and their diet is solely blood. Some species of Vampire Bats tend to feed mainly on birds while others feed on mammals.
There are three species of "vampire" bat. The common vampire bat feeds mostly on the blood of mammals significantly larger than itself, and is unlikely to kill its prey. The white-winged vampire bat, which prefers the blood of birds, might well kill its prey in the process.
No vampire bats do not kill their prey, they just suck blood and that's it I will hardly believe that they can kill a full grown bear even in a swarm
Vampire bats have co-evolved with specific prey species and have adaptations that make them efficient at feeding on the blood of animals like livestock or birds. Human skin is thicker and vampire bats are less likely to bite a human due to their high body temperature and elevated heart rate. Additionally, human activity and sleeping patterns are different from the preferred prey of vampire bats.
No, vampire bats do not have venom. They have special adaptations in their saliva that prevent blood from clotting while they feed, allowing them to obtain a blood meal from their prey without causing excessive bleeding.
They are mainly called that because the behavior of the bats was similar to that of the legendary 'vampire' that would suck blood from humans and animals. Vampire bats drink blood (usually only a few drops) from animals.
If you meant how do they feed off their prey - they bite the animals flesh, and lick at the blood that oozes out. Their saliva contains a mild `anaesthetic' - so after the initial bite, the prey feels nothing.
