Daniel Zurek and Cole Gilbert at Cornell University have been studying the Tiger Beetle for years now: an animal that runs so fast when it runs after its prey, it literally blinds itself.
Beetles have the incredible capacity of sprinting really fast when chasing after their prey or mate; Tiger Beetles specifically can run up to 5 mph, covering a distance amounting to their body’s length up to 120 times — in other words, really really fast. When they do, it becomes basically impossible for them to identify anything, essentially making the world a giant blur to them — a disadvantage that contradicts the entire concept of being able to move at that rate and speed.
However, the inability to see when chasing after their food doesn’t necessarily mean these critters are about to die out of starvation any time soon: As they run, they will often stop to verify their directions,or checking their map-quest, its not certain yet which one. They go so fast that they could literally stop 10 times and still managed to get what they were after.
Nature is so silly sometimes.
