(Inside Science TV) -- Bottlenose dolphins are masters of echolocation but according to what researchers know about sonar, they shouldn't be. Researchers at Saint Mary's College in Notre Dame, Indiana found that bottlenose dolphins direct their sonar to graze their target instead of directly hitting it. At the recent Acoustical Society of America meeting held in Jacksonville, Florida, the researchers presented their findings which revealed that their slightly off the mark strategy is actually mathematically optimal which increases the dolphin's precision in locating its target.
