Dung Beetle crossing the rural road in a straight line
This dung beetle crossed the road in front of my bicycle path in remarkably straight line. Have you tried rolling a ball of poop in a straight line? Me neither, but it cannot be easy. The researchers placed tiny hats on the dung beetles, effectively blocking their view of the heavens, and found the dung beetles could only go straight if they can see the stars.
