Physical Description
The Crested Gecko has hair-like projections found above the eyes, resembling eyelashes. It has a wedge shaped head and a crest that runs from each eye to the tail. The toes and the tip of the semi-prehensile tail are covered in small hairs called setae. Each seta is divided into hundreds of smaller (approximately 200 nanometres in diameter) hairs called spatulae. It is believed these structures exploit the weak van der Waals force to help the gecko climb on most solid surfaces. The toes have small claws which aid in climbing surfaces to which their toes cannot cling. Once they lose their tail it will not grow back.
The Crested Gecko has many naturally occurring color groups, some of which include: grey, brown, red, orange, and yellow of various shades. They have variable markings, which include spots, straight stripes, and tiger-like stripes. The markings and coloration are not geographic indicators; offspring of the same clutch may display differing coloration and markings. The colors are brighter and more prominent at night.
The Crested Gecko has distinct structural morphs in head size and crest abundancy. Geckos with a head length less than 1.3 times its width are considered "crowned" Crested Geckos. They can vary in the amount and size of the crests; some have crests that extend to the base of the tail and some lack crests on one side of their body.

“Let us hope ... that by the best cultivation of the physical world, beneath and around us; and the intellectual and moral world within us, we shall secure an individual, social and political prosperity and happiness, whose course shall be onward and upward, and which, while the earth endures, shall not pass away.”
—Abraham Lincoln (1809–1865)
“As they are not seen on their way down the streams, it is thought by fishermen that they never return, but waste away and die, clinging to rocks and stumps of trees for an indefinite period; a tragic feature in the scenery of the river bottoms worthy to be remembered with Shakespeare’s description of the sea-floor.”
—Henry David Thoreau (1817–1862)
