Liocheliidae

The family Liochelidae, also known as rock scorpions, comprises 56 species that are absent from North America. Previously, they were referred to as Ischnuridae. Scorpions, in general, are arachnids that first appeared in the Silurian Period, over 400 million years ago, and have a basic body plan that has remained largely unchanged. They are opportunistic predators, feeding on insects, spiders, and small vertebrates. Scorpions inhabit diverse environments worldwide, from deserts to mountains, and are primarily nocturnal, hiding during the day.12345
