The desert gossalizard split from its ancestor, the warf gossalizard. They have moved to warmer climates and feed on various species of sapworms. Like their ancestor they are slightly warm blooded and have belly fur for insulation. Their back legs now have an extra toe to help support it when walking or climbing.
Like their ancestor they produce warfarin and use it their silk and saliva. They use their "silk guns" to grab prey from long distances and even directly from the air. When not hunting they spend their time digging burrows to sleep in as well as raise their young in. They will use their silk to help keep the burrows from collapsing. They will also store up prey wrapped up in silk for later. This is useful for leaner times in the winter when there are no sapworms around.
