Sharks can become invisible to their prey - Polidicks

[IMG]http://img522.imageshack.us/img522/3164/shark278x225.jpg[/IMG] [I]velvet belly lantern shark's glowing underside[/I] [release][B]Researchers have discovered some sharks can become invisible to their prey by creating an odd optical illusion. [/B] Emitting light from their body, by regulating the photophores underneath the body, the sharks are able to match the light from the sun. According to researchers from the University of Louvain, this means the already efficient killers don't stand out as silhouettes to their prey - making them even more deadly. Lead researcher Julien Claes says that about 10 percent of known sharks are able to glow, and that this could also be used to attract a mate. We've always worried about being attacked by a shark… but after hearing this will now be glancing even more nervously around the bathroom before getting into the tub. [URL]http://newslite.tv/2010/05/26/sharks-can-become-invisible-to.html[/URL][/release] [release] In open water, there is often no place to hide. Some sharks have overcome this problem by making themselves invisible to both prey and predators, according to a new study. Light trickery permits the optical illusion, described in the current issue of the [I]Journal of Experimental Marine Biology and Ecology[/I]. The findings represent the first experimental tests of shark luminescence. Lead author Julien Claes explained to Discovery News that about 50 different shark species, or more than 10 percent of all known sharks, are luminous. This means they can produce and emit light from their bodies [URL]http://news.discovery.com/animals/sharks-invisible-light-luminescence.html[/URL] [/release] I knew some fish could do this, but never knew sharks could. :tinfoil: :coolfish:

never touching water ever

i wish i could do that

I'm trying to make some witty joke about Sam fisher and Sharks. Hmm.

That's pretty damn cool.

wow, never swimming in the ocean again.

Sharks defend their title as the most efficient carnivore in existence.

The ocean is pure motherfucking MAGIC.

Fucking sharks, how do they work? EDIT: dammit.

That is way too sick.

Hope you guys realize that a human would easily be able to tell the difference between a fake glow and the actual light. Mostly if you directly look at it...what with depth perception.

Well, another reason to stay miles from the ocean.

And to us, we would be able to notice the difference. Not invisible to us, invisible to potential predators.

Sharks are badass.

[editline]10:58PM[/editline] I should also mention the shark in question only grows a little longer than a foot long, and lives in deep waters. However about 10% of sharks emit light. Don't expect to be running into invisible great whites anytime soon.

OvB tells the truth. These things are in no way a danger to anyone.

Well makes sense, seems like they just pop out of motherfucking nowhere.

Somewhere, a writer for The Asylum just had a really, really great idea.

Imagine if there are gigantic megalodons all over the ocean, but we don't know because they're invisible. :tinfoil:

bullshit and i have to go to the beach this july.

Never know what hit em...

This just proves that swimming the ocean is equally deadly as swimming in hydrochloric acid.

Stealth camouflage?!

OP wins an award for most terrifying thread title ever.

Well, I'm never going into the ocean.
