(Piano music stops) Welcome to Ten Things I Like About… I’m Kiersten, your host, and this is a podcast about misunderstood or unknown creatures in nature. Some we’ll find right out side our doors and some are continents away but all are fascinating. This podcast will focus ten, ten minute episodes on different animals and their amazing characteristics. Please join me on this extraordinary journey, you won’t regret it. This is the ninth episode of Bats and if I haven’t convinced you that they are some of the most amazing creatures on the planet yet, this episode will surely do that. The ninth thing I like about bats is all the cool facts about them. Some cool bat facts have been sprinkled throughout the other episodes but it never hurts to talk about fun facts again! Such as…There are 1400 bat species. That’s one thousand four hundred species of bat. They make up 1/5 of all mammals. And they range in size from one of the smallest mammals on the planet, the Bumblebee Bat that weighs only as much as a US penny, to the Flying Foxes that can have a wingspan of six feet! That’s three cool facts in one go. It’s always a party when you’re talking about bats. Bats are found on ever single continent including most islands, expect Antarctica. That’s pretty cool. Very few animals, outside of humans, are found on so many bodies of land. Remarkably, bats have been around in Europe, North America, South America, India, and Australia for millions of years. Bats show up in the fossil record dating back to the Early Eocene which is roughly 47.5 to 55 million years ago. That’s well before humans existed. And…when we study these fossils, they show that bats have changed very little in structure from that time. When animals change very little from the time of their appearance in the fossil record to today that means they are pretty close to evolutionarily perfect. I think that’s very cool. We also know from studying these fossils that bats have been using echolocation from the beginning. Bats have the most well developed echolocation system of any animal, that we are currently aware, of course. Which is a cool fact in and of itself, but it takes it to a whole other level knowing they have been echolocating for millions of years. Bats are the only mammal capable of true flight. Yes, we have flying squirrels but they can only glide. Bats flap their wings to propel them through the air. Similarly to birds, bats can create sustained flight. While we are discussing flight, the Mexican free-tailed Bat is the fastest bat in flight. They are able to reach speeds of 100 mph. That’s fast! Speaking of Mexican Free-tailed Bats, the colony that lives in Bracken Cave in Texas has approximately 15 million individuals making it the largest known bat colony on Earth, as well as the largest concentration of mammals on Earth. The cool facts never end with bats! Let’s talk life expectancy. Typically the smaller an animal the shorter the life span. For example, if you have a pet mouse or rat, they typically live a year to two years, where as your dog or cat can live 10 to 15 years. It’s just physics, but bats break this rule. Most of them are fairly small and on average they can live 20 years. Some species, such as the Little Brown Bat, can live 30 years. The oldest bat, a Brandt’s Bat which is an insectivorous bat, was discovered in 2006 flying wild in Siberia and it was 41 years old! We know the age because this bat was tagged and had a record of lifespan recorded by scientists. That is cool! Some male bats got milk! The male Dyak’s Fruit Bat is able to feed their young from their own mammary glands. It is currently the only known example of natural paternal lactation. Scientists don’t know why. What’s also interesting in this species is that the dads actually have a role in raising their young. That is not common throughout bat species. Dyak’s Fruit Bat is found on the Sunda Shelf of Southeast Asia. All bats have belly buttons! Since they are mammals, they are born live and are connected to mom through an umbilical cord during gestation. Just like us, actually just like almost all mammals. Not all mammals will retain a belly button after the umbilical cord falls off, bats do. Just like humans. That’s cool! Female bats can get pregnant whenever they want! Some...
