Desert Geckos Glow Neon Green In The Moonlight, Scientists Discover (Live Science)
Science headlines about animals are always cool because you find out about something new regarding them. In this story, we find out that the web-footed geckos in the Namib desert glow with fluorescent neon-green light. The light glows along its flank and around the eye when under a strong ultraviolet light. Of course, we know reptiles and amphibians have produced fluorescence in the past. Typically, it comes from their bones or a chemical secretion in their skin.
Yet for the web-footed gecko species, they actually generate the glow by using skin pigment cells, which are filled with guanine crystals. The cells are referred to officially as “iridophores” and they have been linked to color display patterns in other gecko and lizard species. However, this was the first known evidence that the cells can also allow them to glow in the dark too.
