Whitetail deer and their relatives are found throughout the North American continent. They range in size and breeding season depending on their environment. Researchers are studying the Coues whitetail deer, which are only found in the US desert southwest and northern Mexico. This area is much hotter and drier than the North American environment of Saskatchewan (a province of Canada), home to many traditional whitetail deer.

During the high temperatures of early afternoon Coues deer remains relatively inactive.

Also in the desert are many lizard species. One species is a brightly colored desert lizard which is highly poisonous.

One lizard species is known to produce a toxin (X) which causes paralysis.

Toxin X is a specialized protein secreted on the lizard's skin when they are threatened.

The production of toxin X costs lizards a great deal of energy (ATP).

The toxin producing lizards are black and have a bright orange pattern on their back which looks remarkably like Pistol Pete.
