Fringe-toed lizards are lizards of the genus Uma in the family Phrynosomatidae, native to deserts of North America. They are adapted for life in sandy deserts with fringe-like scales on their hind toes hence their common name.
Descriptions
[edit | edit source]Lizards of the genus Uma have a brown and tan coloration that helps them to blend in with the sand. The dorsal surface has a velvety texture with intricate markings. In addition, they also have prominent elongated scales which form a fringe on the sides of their hind toes.[2] These fringes aid with traction and speed, and help the lizard avoid sinking into loose, sandy dunes.[3]
Fringe-toed lizards also possess upper jaws which overlap the lower ones, preventing the intrusion of sand particles, and nostrils that can be closed at will. Flaps also close against the ear openings when moving through sand, and the upper and lower eyelids have interlocking scales that prevent sand from getting into the eyes.[2]
Geographic range
[edit | edit source]Fringe-toed lizards range throughout southeast California and southwest Arizona, and extend into northwest Sonora and northeast Baja California.[2]
Habitat
[edit | edit source]Lizards of the genus Uma are found in low desert areas having fine, loose sand.
Diet
[edit | edit source]Fringe-toed lizards primarily eat insects, including ants, beetles, grasshoppers, and caterpillars. Flower buds, stems, leaves and seeds of plants are also eaten.[2]
Behavior
[edit | edit source]Lizards of the genus Uma bury themselves underground in the winter. They sleep in their burrows, and use their burrows for protection from predators and extreme temperatures.
Species
[edit | edit source]
"Uma rufopunctata", the previous name for the Yuman Desert fringe-toed lizard, was found in 2016 to represent a hybrid between U. notata and U. cowlesi.[5] ||
