Leopard Gecko - VK & NM



The leopard gecko (Eublepharis macularius) lizard is naturally found in the deserts and unlike most geckos, leopard geckos possess movable eyelids.

Ectotherms

A Leopard Gecko is an ectotherm. Ectotherms cannot fully control body temperature by physiological means. Their body temperature changes with the environmental temperature. They are from a naturally hot climate. All ectotherms need a heating gradient- in case they get too hot; they need somewhere to cool down. This is why leopard geckos are usually found under rocks or in shady places.

Methods of Survival

These geckos evolved a survival mechanism by storing fat in their tails when food resources are abundant. Geckos then rely upon this fat reserve during times of drought and prey scarcity. They convert this fat into water and sugar which supply necessary energy and fluids to maintain normal metabolic processes.

While captive Leopard Geckos generally remain active all year round, while wild specimens become dormant during the colder months. Leopard gecko species are nocturnal. This means that they sleep most of the day and become active at night or as the sun sets and rises in order to prevent water evaporation. Extra-thick skin also helps to prevent drying out in the desert Leopard geckos conserve water by excreting nitrogenous wastes in the form of uric acid (solid crystal form) as opposed to urine.
