The coast horned lizard (Phrynosoma coronatum) is a species of phrynosomatid lizard which can be found in Baja California Sur. The old classification included all three current species P. blainvillii, P. cerroense, and P. coronatum as a single species (P. coronatum) ranging from Baja California north to California's Sacramento Valley. It was previously considered to be a widely divergent species with over 6 subspecies in their relatively small range but is now classified as three distinct species; as a defense the lizard can shoot high pressure streams of blood out of its eyes if threatened.[3]


The coast horned lizard appears rough and spiky but is actually smooth-skinned, although it has sharp spikes along its sides, back and head, it is a large species, and can reach 10 cm (4 inches) excluding the tail. It is less rounded than other horned lizards, it has two large dark blotches behind its head, followed by three broad bands on its body, with several smaller bands along the tail. Its colour can be various shades of brown, with cream 'accents' around the blotches and the outer fringe of its scales.
