There was once a thriving group of reptiles that lived during the time of the dinosaurs. Rhynchocephalia is a reptile order that evolved around 240 million years ago. These reptiles used to live ...

A series of clever experiments into the reptilian "third eye" has confirmed that lizards use this patch of light-sensitive cells as a sun-calibrated compass. To test how third eyes — technically known ...

SMBE Journals (Molecular Biology and Evolution and Genome Biology and Evolution) The vertebrate eye is a remarkable evolutionary invention, displaying an incredible repertoire, from a soaring falcon's ...

Lizards have given Johns Hopkins researchers a tantalizing clue to the evolutionary origins of light-sensing cells in people and other species. Published in the March 17 issue of Science, their lizard ...

Lizards have a little dot at the top of their heads that is called a “parietal eye.” This eye is not as complex or as useful as the two in the front of their heads, but it does react to light. Are ...

The third, or parietal, eye of lizards and other lower vertebrates mediates the detection of dawn and dusk instead of conventional image-forming vision. The parietal eye photoreceptors resemble their ...

Many people know that some animals have more than two eyes, but the variety and function of these extra eyes might surprise you. From reptiles with a hidden “third eye” that senses light, to insects ...
