Scientists have discovered species such as Enneapterygius pusillus glow red when viewed through a red filter. Photo by Nico Michiels et al. Full write up at Live Science.
“The red glow is likely a form of private communication or an attraction signal, Michiels said, though he doesn’t have clear proof yet. Because the light is coming from the fish themselves and not filtering down from the surface, the red glow remains visible at depth and is easily seen at close distances only.”
“Fluorescence occurs when light is absorbed at one wavelength and then re-emitted at another nearly immediately. In the case of the red fluorescence, these fish absorb light at blue-green wavelengths and re-emit it at red.”

Sustainable Seafood efforts surge after dismal report on American Freshwater Fish numbers. The last time a study of this size occurred was in 1989. Fast forward to today, and 92% more species are now in believed to be in jeopardy. Full story at The Monterey Bay Aquarium Blog. Sidenote: The aquarium has recently closed their Jellyfish exhibit to make way for the exhibit, “The Secret Lives of Seadragons” that will house Leafy Sea Dragons.
How do Coral Reefs fare after being nuked? Not so bad after all, at least at the Bikini Atoll which were vaporized in 1954 thanks to a hydrogen bomb. According to Maria Beger of the University of Queensland in Australia, ”apart from occasional forays of illegal shark, tuna and Napoleon Wrasse fishing, the reef is almost completely undisturbed to this day.”
