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.

Famous quotes containing the words physical and/or description:
“The peace loving nations must make a concerted effort in opposition to those violations of treaties and those ignorings of humane instincts which today are creating a state of international anarchy and instability from which there is no escape through mere isolation or neutrality.... When an epidemic of physical disease starts to spread, the community approves and joins in a quarantine of the patients in order to protect the health of the community against the spread of the disease.”
—Franklin D. Roosevelt (1882–1945)
“I was here first introduced to Joe.... He was a good-looking Indian, twenty-four years old, apparently of unmixed blood, short and stout, with a broad face and reddish complexion, and eyes, methinks, narrower and more turned up at the outer corners than ours, answering to the description of his race. Besides his underclothing, he wore a red flannel shirt, woolen pants, and a black Kossuth hat, the ordinary dress of the lumberman, and, to a considerable extent, of the Penobscot Indian.”
—Henry David Thoreau (1817–1862)
