About Xantusia henshawi

Granite Night Lizard

The granite night lizard, scientifically known as Xantusia henshawi and also commonly called Henshaw's night lizard, is a species of lizard native to North America. This reptile is found in both Mexico, specifically in the state of Baja California, and in the adjacent southern regions of California in the United States.

Description and Habitat

This lizard is notable for its flattened body, broad and flat head, and characteristically soft skin. Its dorsal surface is adorned with rounded, dark spots set against a pale yellow or cream-colored background. The scales on its back are granular, while those on its belly are large and squarish. A distinctive feature is its large eyes, which possess vertical pupils, and the absence of eyelids. The granite night lizard typically inhabits rocky slopes that are abundant with large, exfoliating boulders and numerous crevices. However, it can also be found in coastal sage scrub and chaparral environments, sometimes even where boulders are scarce.

Behavior and Reproduction

The granite night lizard exhibits a unique behavioral pattern: it is active within crevices during daylight hours but emerges to move across the surface during the night. This species reproduces by laying eggs, classifying it as oviparous.
