nothing to fear but fear itself. and invisible sharks.
i'm never going into the ocean un-armed again.
Sharks Can Become Invisible
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 Journal of Experimental Marine Biology and Ecology. The findings represent the first experimental tests of shark luminescence.
"I believe that what most surprised and excited me about this paper was the finding that the emission of light on the ventral surface of the sharks closely resembles the environmental light," Coelho said, "allowing the sharks to efficiently camouflage themselves by counter-illumination, remaining invisible to both possible predators and potential prey."
