Alligator Lizard, Elgaria multicarinata multicarinata

California native

The different species range through a variety of habitats, generally frequenting moist areas of foothills and mountains, but also found ranging down into the drier grasslands, staying near rivers and streams. Secretive in nature, they hide under windfall, undergrowth, and in rocky crevices. Pugnacious when caught, they will thrash around, often delivering a painful bite. 

close-up of an alligator lizard's headAlligator lizards sport a flat, wedge-shaped head. There is little neck definition, with the body about the same width as the head. The legs are small, thin, and end in five fine toes. Notable is a distinct lateral fold running along their lower sides from the corner of their mouth to their tail. Their scales are large, slightly keeled, and shingled. Ground color is pale to medium brown with darker crossbands. They shed in one piece, like a snake. 

Temperatures
Daytime temperatures should range from 70-80 F (21-26 C), with a basking area of 85-90 F (29-32 C). Nighttime temperatures should drop to 65-75 F (18-24 C). UVB lighting required, or regular access to unfiltered sunlight. 

Food
Insectivores, they feed mainly on arthropods, snails, and occasionally eggs. In captivity, larger animals may feed on mice. Diet must be supplemented with multivitamins and calcium. 

Reproduction
Most species are egg layers, with females guarding their eggs. G. coeruleus (Northern Alligator lizard) and some montane species are ovoviviparous.

This alligator lizard had a close call very recently, notice the fleshy wound at the tail. How did that happen? Can you guess?The alligator lizard on the left just lost it's tail, can you guess how? 

If you catch a lizard at Kaweah Oaks Preserve, please observe it with gentleness and care then release back into its own habitat. Thank You
