Xenosauridae

The Xenosauridae is a family of lizards native to Central America and China. Also known as knob-scaled lizards, they have rounded, bumpy scales and osteoderms. Most species prefer moist or semi-aquatic habitats, although they are widespread within their native regions, with some even inhabiting semi-arid scrub environments. They are carnivorous or insectivorous, and give birth to live young.
