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.

How illuminating. Dazzling even. I hope you are not trying to blind us with science! :)

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.
