I’ve been waiting ten years to write that headline. My career as a blogger is now complete. As it says, Dr. Evil’s vision of “sharks with frickin’ laser beams attached to them” is now a reality. And as it turns out, this story actually has a lot to do with in-the-wild testing.
Here’s Wired.com on the details:
Marine biologist-cum-TV personality Luke Tipple attached a 50-milliwatt green laser to a lemon shark off the coast of the Bahamas in late April. The escapade was sponsored by Wicked Lasers, a consumer-focused laser manufacturer based in Hong Kong that produces some of the most brilliant — and potentially dangerous — handheld lasers in the world.
“This was definitely a world first,” Tipple told Wired. “Initially, I told them no. I thought it was a frivolous stunt. But then I considered that it would give us an opportunity to test our clips and attachments, and whatever is attached to that clip, I really don’t care. It was a low-powered laser that couldn’t be dangerous to anyone, and there’s actually useful applications in having a laser attached to the animal.”
Tipple said the experiment was instructive in a number of ways. For starters, he was able to further test his clamping apparatus, which is typically used for traditional data-aquisition equipment.
He also wanted to verify anecdotal evidence that sharks avoid laser energy of specific spectrums and wavelengths. Curiously, at least with the Wicked Lasers model, he found the opposite to be true: “Although further testing is necessary, time and time again, sharks were actually attracted to the laser beam,” he said.
Finally, he said the experiment was helpful in measuring a shark’s velocity and trajectory in real time. “We were able to see how their body positioning relates to a target,” he said. “You can get a very clear description, via the laser, of what the shark’s body is doing.”
