Heartbeats Unimaginably So Very Slow

I never knew before that some animals can have heartbeats unimaginably so very slow. The heart has to pump blood through its intricate system of arteries, veins and valves towards the lungs to remove carbon dioxide and to allow general blood circulation in an animal's body through a major artery, the aorta. This mechanism serves the following functions: provide much needed oxygen, remove carbon dioxide from the blood, distribute nutrients, and remove bodily waste in general.

Among those animals known to have the slowest heartbeat are the blue whales at four heartbeats per minute. It can afford to do so because of its big size. Browsing the internet, I discovered that a relatively smaller animal can even have a slower heartbeat at only two heartbeats per minute. These are the crocodiles.

Blood-Sucking Vampire Bats

Are vampire bats really blood-sucking mammals as its name connotes?

While looking for facts about this mammal, trying to verify if these animals are really blood-sucking like vampires are portrayed on stories and films, I discovered a lot of facts. While these animals are associated with the supernatural and treated with disdain, they serve some purpose to man. They are not blood sucking but may surreptitiously feed on any warm-blooded animal including man.
