Desert Horned Lizard
Phrynosoma platyrhinos
The Desert Horned Lizard. Flattened and covered in sharp spines, it perfectly mimics desert gravel. An extreme specialist: its diet in the wild consists almost exclusively of harvester ants.

Care, breeding and tankmates
Terrarium Setup: They demand abundant horizontal space. An adult requires a minimum desert terrarium of 48x24x24 inches (120x60x60h cm). The ideal substrate is calcareous desert sand mixed with clay, so they do not sink. Large sturdy branches and rocky platforms (basking spots) must be placed right under the heat light. It is vital to guarantee immense side vents to ensure non-existent humidity.
Lighting and Heating: Reptiles with EXTREME lighting needs. The basking zone must have a metal halide or spot lamp firing directly on the rock, reaching the impressive temperature of 104-108°F (40-42°C). The cold zone of the terrarium must stay at 78-82°F (26-28°C). Furthermore, the use of a high-intensity T5 UVB tube (12-14% UVB) along at least half the terrarium is NON-NEGOTIABLE. Without this scorching and radiant setup, they will stop digesting and suffer from bone rickets.
Humidity and Hydration: Strictly desert-dwelling species. The ambient humidity must remain between 30% and 40% (practically heated home air). High humidity causes fatal respiratory infections. They drink very little from standing water: most of the hydration is absorbed from the fresh greens they ingest. A shallow bowl can be provided, but they often prefer to bathe in it rather than drink.
Feeding and Supplementation: They are omnivores whose diet changes drastically with age. Hatchlings are 80% insectivorous and devour dozens of crickets/roaches a day. Adults reverse the ratio: 80% dark leafy greens (dandelion, arugula, chicory, endive) served daily in mixed salads, and 20% live insects twice a week. Insects and salads must be constantly dusted with Calcium (daily) and Multivitamins (weekly).
Compatibility: Asocial and highly territorial. Two males together will brutally tear each other apart. Although sometimes sold in pairs, solitary keeping is the main rule: males stress females to exhaustion with continuous mating attempts. No other animal should enter their enclosure.
Health and Common Diseases: MBD (Metabolic Bone Disease) due to poor UVB leads to tremors, rubbery bones, and shortened jaws. Another scourge of adults is Obesity and Hepatic Steatosis (Fatty Liver): owners tend to overfeed them with fatty prey (mealworms, superworms) refusing to make them eat salad, causing them to die from organ collapse in a few years.

The catalog's scalar value is 9.5 cm. The ReptTraits v1.2 source reports a maximum adult measurement of 9.5 cm for this species, recorded as snout–vent length (SVL). These figures are not interchangeable: the first is the profile's editorial reference, whereas the second is a published maximum under a specific measurement convention; differences among sources can reflect sex, population, life stage and measuring method.
