The pineal gland of evolutionarily older
animals, such as lizards and amphibians, is
also called the 'third' eye. Just like the two
seeing eyes, the third eye possesses a lens,
cornea, and retina. It is light-sensitive and
helps regulate body temperature and skin
coloration-two basic survival functions
related to environmental light.
