New research says that being a blind bat has its good sides - in fact, when wild bats use their vision to fly they are more likely to crash! Bats normally navigate by sending out sound waves and listen to echoes bouncing off their prey. They are also able to navigate visually, but the vision gets worse the brighter it gets. Scientists tested this by setting up an obstacle course in Ontario. They used 3 different light conditions - dark, dim, and bright. The results showed that the vision caused them to crash, but the bats still chose to use it in the well-illuminated course.
I thought this article was very interesting because although I knew that bats used their hearing for navigation, I never knew that they were actually able to see. I thought they used their hearing because they had terrible vision or something. This is yet another example of how animals use adaptations to help them survive and find prey. It is also probably what makes bats such great hunters.
Haha I loved this article it was a great one to do for your last current even
