Any guesses?

They also have the slowest reproductive rate of any animal

sonar system called echolocation to locate their prey and navigate their surroundings. If you guessed

skeletons don't fossilize well, but we do know that bats have been around for at least

50 million years. They likely started out terrestrial or confined to the treetops, but over time
