copperstream Posted February 21, 2008 Posted February 21, 2008 Do you know why do the eyes of some animals glow in the dark ? The truth is that the glow is only the reflection of light from a source. the reason that the reflection takes place is that there is alayer of crystalline substance in the eyes. the animals that have more blood vessels in their eyes emitt a reddish glow.
Sayonara Posted February 21, 2008 Posted February 21, 2008 How illuminating. Dazzling even. I hope you are not trying to blind us with science!
thedarkshade Posted February 21, 2008 Posted February 21, 2008 Oh, and I love how the eyes of a panter glow in the movies!

The structure in question is know as a tapetum lucidum (it means bright carpet). The structure is primitive for vertebrates and reflects light to aid in nocturnal visions. Monkeys, apes, and humans (anthropoids) lack a tapetum, as do tarsiers interestingly.
