To defend himself, the horned frog employs several unique strategies. The horned frog's coloring closely matches the ground and dirt where he lives, which is hot, dry and sandy environments of North and Central America.

As a result of effectively blending into the environment, the horned frog is more difficult for predators to spot. The back and head of the horned frog is typically desert gray, and body markings are various shades of yellow, tan, brown or red.

With the ability to quickly change his coloring from light to dark or vice versa in only minutes, a horned frog can further camouflage himself from a predator hot on his trail.

When threatened, the horned frog's initial defense is to stop in his tracks and remain completely still. If the predator moves closer and he's forced to move, the horned frog will quickly run a short distance, abruptly stop, run again and then stop, which confuses the vision of the predator.

During hot weather, Short-horned Lizards are most active during the morning hours, with less activity in the afternoon. Short-horned Lizards can quickly burrow into loose soil to hide.

They use their small claws for digging and climbing. Though they are infamous for their ability to squirt blood from their eyes to deter predators, it is their thick skin that allows horned lizards to thrive amid the harsh conditions and plentiful predators of the desert.

They can be found in arid and semiarid habitats in open areas with sparse plant cover. Because horned lizards dig for hibernation, nesting and insulation purposes, they commonly are found in loose sand or loamy soils.

In order to ward off hungry predators, short-horned lizards are capable of inflating their bodies up to twice their size, resembling a spiny balloon.

And temperatures matter. From there is either falls off or is deftly removed by a delicate flick of the lizards hind foot. Many animals use a phenomenon known as thanatosis or tonic immobility as a last resort to appear dead and avoid being killed by predators. Randomly arranged filaments scatter all wavelengths of light, and their optimized spacing maximizes the effect. The shell of a tortoise withstands pressure through interlocking scutes of various shapes consisting of both rigid and flexible layers.

A distinct set of hormones alter insect behavior by changing metabolic function during times of stress. We use cookies to give you the best browsing experience.

Introduction North American desert horned lizards have a wide range of predators within their habitat.

The Strategy The horned lizard has two constricting muscles that line the major veins around its eye.
