Have you ever wondered what would happen if you blindfolded a spider? Well, a team of presumably very bored entomologists at the University of Nebraska have managed to do just that. However, and to the scientists’ credit, the spider that they managed to somehow blindfold is not just any spider. The spider in question possesses the largest eyes known to science. This spider has been named Deinopis Spinosa and is found in Australia, Africa, and the Americas.
This spider hunts prey at night, which could be why this spider has evolved a pair of abnormally large eyes, which, combined, equal eight eyes in total. A very dedicated biologist was not content with this theory and decided to camp out in the spider’s habitat for a total of eight months to see how it would behave after he blindfolded it with dental silicone.
It turns out that these blindfolded spiders could not catch ground dwelling prey as easily as they could with the use of their eyes, but their ability to catch flying prey remained largely unaffected. This is likely due to the spiders preferred taste for ground dwelling insects, as they tend to be more nutritious. Why do I get the idea that this entomologist just really loves camping?
Can you think of an insect that wouldn’t be negatively affected by being blindfolded? How would they adapt to survive without sight?
