Are bats actually blind, or has everyone been saying that phrase wrong for centuries?

We get into what bats can really see, starting with echolocation and why it evolved for hunting in darkness rather than to compensate for bad eyesight. You'll learn the difference between megabats and microbats, how ultraviolet vision shows up in some species, and what a 2019 study on vision genes across 111 bat species actually found about the tradeoff between sonar and sight.

Turns out the phrase gets the whole situation backwards.
