Regal horned lizard
|Regal horned lizard|
The regal horned lizard is a small, flat lizard about the size of the palm of a man's hand. Though it has spikes all around its body, the regal horn’s main defense is the ability to squirt blood from its eyes.
3-4 inches in length from nose to tail as a full adult.
Pale grey to yellow-brown or reddish topped with dark blotches along side the body and back.
4 legs each leg with 4 toes and claws on each leg.
slow runner uses camouflage to escape predators
This lizard can be found across southeastern Arizona and along the transition of the southern zone of the central mountains region.
Can be found primarily in a hot and dry climate where the Earth may be covered in limestone dust
Sonoran Desert Mountains is where it prefers its climate, but can be found in Texas,southern California, Arizona, and New Mexico
They eat mostly harvester ants, and can eat twenty-five hundred ants in one meal. They are slow eaters, because they spend most of their time in the intense heat of the desert during meals.
Eats flies, spiders, and a variety of insects.
This is a year-round active type of lizard, but during winter, its activity is usually restricted to unseasonably warm days. They may hibernate late September through October. It looks for shelter from cold temperatures by digging holes in the ground. When it is threatened or captured, it squirts blood from its eye. This blood may have a taste used to deter predators. If the camouflage and intimidation does not work, that is when they squirt out blood aiming for the predators mouth and eyes. This stream can range up to 4 feet and may be repeated several times. The stream comes out through its lower eye-lids pores. Some other defensive behaviors include gulping air and poking with the horns. 
Mating for the Regal Horned lizard begins in late April, peaks in June, and stops abruptly in July. Egg laying starts a few weeks later, usually in late July and early August. About 10-30 eggs are laid on average usually 15. The eggs are laid in the sand and are required to stay there for several weeks. The egg shells are white and flexible and average about one-half inch in diameter. The hatch-lings receive no parental care upon hatching and immediately bury themselves in the sand. They are now responsible for finding and hunting for their own food. Several diverting tactics are used to attract a mate, such as: head bopping, push ups, and nodding of the head.
