Leopard Gecko — Murphy Patternless

Geographical Origin and Habitat: Inhabits the arid highlands, steppes, and rocky desert areas of Northern Pakistan, northwestern India, and Afghanistan. It is a terrestrial reptile that shelters in humid rock crevices during the hot day.

Taxonomy and Genetics: Belongs to the family Eublepharidae. The 'Murphy Patternless' morph is a simple recessive mutation that completely deletes the wild-type spots and patterns, yielding a clean, solid body color ranging from olive-green to mustard or lavender.

Behavior and Habits: Docile, gentle, and curious. These geckos are strictly crepuscular and nocturnal. They navigate their environment using excellent eyesight and a highly developed sense of smell, storing fat reserves in their thick tails.

Morphology: Robust terrestrial geckos reaching 20-25 cm. United by moveable eyelids and a lack of adhesive toe pads, having claws instead. Males have prominent preanal pores in a V-shape and visible hemipenal bulges.

Terrarium Setup: A horizontal glass terrarium (minimum 80x45x45 cm) is recommended. The substrate can consist of a bioactive desert soil mix (clay, sand, and peat). Provide at least three hides: one in the warm zone, one in the cool zone, and a humid hide filled with damp sphagnum moss to facilitate shedding.

Lighting and Heating: Crepuscular animals that absorb heat from warm rocks. Provide a heating mat or under-tank heater controlled by a thermostat to maintain a warm zone floor temperature of 30–32°C. The cool end should stay around 24°C. Provide a light UVB source (ShadeDweller 7%) to assist with calcium metabolism.

Humidity and Hydration: Keep ambient humidity low, around 30–40%. A shallow fresh water dish must always be present. The humid hide must be kept damp to prevent shedding issues, particularly on the toes, which can lead to necrosis if skin is retained.

Feeding and Supplementation: Strictly insectivorous. Feed live crickets, dubia roaches, and occasionally mealworms or hornworms. Dust all prey items with pure calcium at every feeding, and add calcium with D3 and multivitamins once or twice a week.

Compatibility: Solitary animals. Never house two males together as they will fight to the death. A male can be housed with females only in large terraria, though individual housing is generally recommended.

Health and Common Diseases: Monitor the tail thickness; a thin tail ("stick tail") indicates malnutrition or severe parasitic infections (like Cryptosporidium). Avoid rough handling to prevent autotomy (tail drop). Re-grown tails will be bulbous and lack the original segmented look.
