The phrase "blind as a bat" has convinced many children that bats cannot see.
All bat species can see. Many also use echolocation.
What the evidence shows
- Every bat has eyes. No bat species is blind. Large fruit bats and flying foxes have excellent vision and do not echolocate.
- Echolocation plus sight. Many smaller bats use echolocation to hunt insects at night, but they also use vision, especially for long-distance navigation.
- Color. Some bats can see ultraviolet light.
Why it matters
Myths about bats can make children fear useful animals. Bats pollinate plants and eat huge numbers of insects.
