Submission + - Biologist fits sharks with lasers (phys.org)

PvtVoid writes: Marine biologist Luke Tipple mounts 50 milliwatt S3 Krypton lasers to lemon sharks to study shark movements in the water. "Tipple said that clipping the laser onto the dorsal fin and flipping on the laser was easy, although the shark didn’t like it when Tipple first attached the clamp. He said a few seconds later 'it returned to normal behavior.'"
