Bioflourescence in fish

A new discovery reported on 1/8/2014:

 "...a variety of fish living around coral reefs -- including sharks, rays, eels and lizerdfishes -- that exhibited bioflourescence [under blue light].

"So how do the fish recognize it? Many of them have yellow filters in their eyes, "possibly allowing them to see the otherwise hidden fluorescent displays taking place in the water," a news release from the museum of natural history said.

However,

"...the need for special technology to view what the website called weak fluorescence "casts doubt on the usefulness of the coloration in the fish's dimly lit natural environments."
