"A remarkable new discovery shows the four-eyed spookfish to be the
first vertebrate ever found to use mirrors, rather than lenses, to
focus light in its eyes." - Daily Telegraph

"A Pacific fish uses mirrors as well as lenses to help it see in the
murky ocean depths, scientists have revealed." - BBC

"The odd-looking spookfish is the only vertebrate known to have
mirrors in its eyes, according to a new report. The mirrors gather and
focus light better than lenses, which spookfish also have, and appear
to be an adaptation for living in the murky depths of the Pacific
Ocean. Scientists discovered the spookfish’s unusual anatomy after
examining the first specimen of the fish ever caught alive." -
Discover Magazine

"Spooky spookfish has freaky eyes" - Nature.com

"This proves the theory of evolution is wrong" - Father Neuhaus if he
hadn't just passed away

Do you really need to pay subscription to _Nature_?? I could read
this quality of coverage in _The Onion_! :-)
