Eastern Fence Lizard
The Eastern Fence Lizard (Sceloporus undulatus) is a medium-sized, spiny lizard native to the eastern United States, recognized for its rough, keeled scales and striking blue patches on the bellies and throats of adult males.
Origin Story
First described in 1801 by Palisot de Beauvois, the Eastern Fence Lizard is a naturally occurring species with no known captive breeding origin. It inhabits a broad native range spanning from New York and New Jersey southward to Florida, west to Texas and Oklahoma, and north into parts of the Midwest.
Classification
Belonging to the genus Sceloporus within the family Phrynosomatidae, the Eastern Fence Lizard is part of the diverse group of spiny lizards. It has been historically classified with several subspecies, though recent taxonomic revisions have elevated some former subspecies to full species status.
Appearance or Form
This lizard typically measures between 10 and 19 centimeters in total length and features a robust body covered with rough, keeled scales. Adult males are distinguished by bright blue patches on their bellies and throats, while females and juveniles display gray or brown coloration with wavy crossbands. Its moderately long tail complements its sturdy form.
Behavior or Usage
The Eastern Fence Lizard is diurnal and primarily terrestrial, often seen basking on logs, fences, and rocky outcrops. It is a capable climber and exhibits rapid, jerky movements when disturbed. Ecologically, it plays a role as an insect predator and is adapted to colder climates by entering a state of brumation during winter months.
