In Humans vs. Flies: Why It's So Hard to Catch a Fly, host Harith Iskander explores how flies can quickly evade capture due to their nearly 360-degree vision. Flies have unique vision which makes them incredibly agile and fast, helping them react in an instant when a threat approaches. Learn how and why catching one is often more difficult than we think. This video is excerpted from BBC’s Got Science?, a science magazine series that explores and explains science in everyday life.
