You know that little pink part in the inside corner of your eyeball, right next to the bridge of your nose? It's the kind of ...

Research study explores how genetic changes shaped the variety seen across primates — from brain development and body size to diet, vision, movement and survival in extreme environments.

1 The researchers measured light wavelengths reflected off the butterflies' tapetum lucidum and found a spectral range of 31 nanometers. They then partially cloned the gene for opsin and found that ...

This ability to see in near darkness is enhanced by a layer behind the retina called the tapetum lucidum. Similar to that found in domestic cats, the tapetum acts like a mirror, intensifying weak ...

Dogs also have a layer of eye tissue that humans lack called the tapetum lucidum, it reflects light into the retina. This boosts dogs' night vision even more and is why dogs' eyes shine in the dark.

Ring-tailed lemurs look different! They retain a number of primitive mammalian traits. For example: Reflective tapetum lucidum, which is a layer of cells in the wall of the eye that reflects light ...

Like cats, an alligator has a tapetum lucidum at the back of each eye – a structure that reflects light back into the photoreceptor cells to make the most of low light. The colour of eyeshine differs ...

The part that changes colour is called the tapetum lucidum. It is a shiny, mirrored layer behind the retina that helps some animals to see in the dark. When light enters the eye much of it hits the ...
