"It’s a good alternative to drilling holes through the fins. "I like the idea of the spring-loaded hinge that's going to break down over time in the salt water," Van Sommeran told Wired. Sean Van Sommeran, executive director and founder of the Pelagic Shark Research Foundation, said he was interested in Tipple's efforts to build a better fin clamp. You’re just causing unnecessary stress on the animal. But if this is just to respond to a scene in the Austin Powers movie, I don’t see value. In terms of the goal, without knowing the specific scientific or educational application, it’s hard to say.
"I don’t think it's going to cause any damage to the shark. "I would say the attachment process sounds non-invasive," Hammerschlag said. "Is there a point of it? It has to have an objective," Neil Hammerschlag, an assistant professor with the Rosenstiel School of Marine and Atmospheric Science, told Wired. And, indeed, Tipple's team was able to retrieve the host shark by the end of the experiment, and remove the clamp. In other words, the shark was easily corralled and size-appropriate, and probably wouldn't stray very far during the stunt. Tipple says he chose a lemon shark - Negaprion brevirostris - for its "predictable and relatively docile swimming behavior during the day, ease of access in shallow water, and size of the dorsal fin." Tipple says the laser was attached to a lemon shark's dorsal fin via a "non-invasive clamp" applied by a diver to ensure correct positioning. This isn't a beam that can be safely shined in anyone's eye, but it's nowhere near as dangerous as the 1-watt Krypton model Gadget Lab tested in October 2011. Where a simple laser pointer might generate a beam measuring about 2mW in power, the shark-deployed model, operating on its low-power setting, emitted a beam in the neighborhood of 50mW. Wicked Lasers supplied Tipple with the lowest-powered version of its S3 Krypton green laser. But for now, let's describe exactly what went down in the Caribbean on Apr. Other experts find the Wicked Lasers stunt of dubious value, and we'll get to those criticisms soon.
