Ecology and Behavior
The Crested Gecko has no eyelids; a transparent scale, or spectacle, keeps its eyes moist and it uses its tongue to clear away debris. Like all Rhacodactylus geckos, it has webbing on its legs and digits. They are a mostly arboreal species, preferring to inhabit the canopy of the New Caledonian rainforests, and because of this they can jump considerably well. They are primarily nocturnal, and will generally spend the daylight hours sleeping in a secure spot in a tree. The Crested Gecko, unlike the closely related Gargoyle Gecko (Rhacodactylus auriculatus), will not regrow its tail once lost. The cells around the base of the tail are brittle, allowing the tail to break away when threatened or caught by a predator. The capillaries to the tail will close almost instantly so there is little to no blood loss. The tails will move independently of the body for 2–5 minutes. The loss of their tail is not problematic, and most adults in the wild do not have their tails.
Unlike most species of gecko, this species is an omnivore, also considered frugivorous, feeding on a variety of insects and fruit. They are often compared to the Leopard Gecko in temperament, often liking being held by their owners and aren't overly aggressive.

Famous quotes containing the words ecology and/or behavior:
“... the fundamental principles of ecology govern our lives wherever we live, and ... we must wake up to this fact or be lost.”
—Karin Sheldon (b. c. 1945)
“The inability to control our children’s behavior feels the same as not being able to control it in ourselves. And the fact is that primitive behavior in children does unleash primitive behavior in mothers. That’s what frightens mothers most. For young children, even when out of control, do not have the power to destroy their mothers, but mothers who are out of control feel that they may destroy their children.”
—Elaine Heffner (20th century)
