00:00 Bats are cool and cute animals that have echolocation abilities and are often misunderstood.

04:45 Bats are the only flying mammals and there are about 1,200 species of bats, which are more closely related to humans than other animals like foxes or rats.

09:27 Bats can be classified into two suborders based on what they eat, with micro bats being carnivorous and eating insects, while mega bats are herbivorous and eat plants.

14:21 Bats likely evolved from a tree dwelling mammal and flying developed before echolocation, according to fossil evidence.

19:24 Bats use echolocation to locate their prey, such as mosquitoes, by creating sound waves and listening for the echo to determine the distance.

24:18 Bats use echolocation to determine the distance, location, size, and direction of their prey, and they also use the Doppler effect to determine if something is moving towards or away from them.

29:07 Bats hang upside down because it requires no energy and allows them to sleep while still being able to clamp onto whatever they're hanging from.

34:01 Bats can control their internal temperature and metabolic rate, allowing them to conserve energy while they sleep and hibernate, and they are also important for pollination and pest control.

39:13 Vampire bats have sharp teeth and use an anticoagulant in their saliva to open up a vein and lap up blood, and they have a heat-sensing organ to find blood close to the skin; bats reproduce once a year and form maternal colonies within larger colonies, and female bats can delay fertilization to have a baby bat at the best time; bats are facing a threat from white-nosed fungus, which wakes them up during hibernation and causes them to use up their energy and potentially die.

43:54 White-nosed fungus is a deadly threat to hibernating bat colonies, with mortality rates as high as 90-100%, and bombing caves full of bats to prevent rabies outbreaks is ineffective and kills off bats that aren't spreading rabies.
