Would a shark with lasers be the ultimate underwater killer? Marine biologist Luke Tipple attached a 50-milliwatt green laser to a lemon shark off the coast of the Bahamas in late April.The company Wicked Lasers sponsored the stunt to test their non-invasive clamping devices. The S3 Krypton green laser were used in a low-power setting, emitting a beam of 50 megawatts. Comparatively, a simple handheld laser generates a beam only 2 megawatts in power. Lemon sharks are relatively docile during the day making them easy targets for such experiment. However, a shark outfitted with a laser for too long might just make itself a target for prey, according to scientists.
