The Coast Horned Lizard
(CHL) is found in California coastal and inland regions from sea level to 8000 feet (2348m), hence from grasslands and Coastal Sage Scrub (CSS) vegetation to pine forest (Jennings, 1988).
Although lizards belonging to the short-horned lizard
clade have more robust morphologies, including a greater bite force, compared to all other horned lizard
species, morphological data for Phrynosoma douglasii were not included in Meyers et al.
And they're enlisting the services of the horned lizard
to carry their part of the research load.

of Arizona's ace is to rupture the capillaries in its eye and shoot a jet of bitter tasting blood at its adversary.
For example, the Texas horned lizard

Although we can't quote exact numbers, most biologists agree there has been a steady decline of Texas horned lizard
numbers over the past 20 years," says Jeremy Garrett of the Oklahoma Department of Wildlife Conservation.
All of the species in South Dakota except the horned lizard

Flat-tailed Horned Lizard
(Phrynosoma mcallii) On January 3, we withdrew our earlier proposal to list this reptile as threatened, based on a determination that listing is not warranted at this time under the terms of the ESA.
Along this spectrum of thermoregulatory behavior, the Texas horned lizard
(Phrynosoma cornutum: Phrynosomatidae) is a thermoregulator that maintains its body temperature within a zone ranging from approximately 35-39[degrees]C (Heath, 1965; Prieto and Whitford, 1971).
