No need for sophisticated hunting techniques: Equatorial bats live the easy life
Most of the world's bats use extremely sophisticated hunting techniques, but not bats around the equator. They use pretty much the same less sophisticated hunting techniques as their ancestors did millions of years ago. They ...
