If you’ve ever seen a bat flying around at sunset, chances are good it was a vesper bat. They’re the biggest bat family, made up of 500 species, found on every continent except Antarctica. And most of them look a lot alike—they’re little, with fuzzy grayish-brown fur, sort of the sparrows of the bat world. That can make it hard to tell the different species apart. But scientists just discovered three new species and two new genera of vesper bats in Africa by comparing the bats’ genes, their teeth and skulls, the high-frequency calls they make when echolocating, and the tiny bones in their penises.
