Lizards are present in Tennessee, contributing to the state’s diverse wildlife. These reptiles are a natural and beneficial component of Tennessee’s ecosystems, playing roles in insect control and the food chain.
Common Lizards Found in Tennessee
Tennessee is home to several common lizard species, each with distinct features. The Common Five-lined Skink (Plestiodon fasciatus) is frequently seen statewide, characterized by a shiny body, typically brown or black, with five white or yellowish stripes extending onto its tail. Juveniles of this species are notable for their bright blue tails, which tend to fade as they mature.
The Broad-headed Skink (Plestiodon laticeps) is the largest skink in Tennessee, identifiable by its broad head and smooth scales. Adult males develop an olive-brown coloration with swollen, reddish heads during breeding season. Females and juveniles resemble the Common Five-lined Skink but are distinguished by specific scale patterns. The Southeastern Five-lined Skink (Plestiodon inexpectatus) also has five stripes and a bright blue tail in younger individuals, with a thinner middle stripe.
Eastern Fence Lizards (Sceloporus undulatus) are widely distributed across Tennessee and are the only spiny lizards in the state. They possess keeled, pointed scales and range from grayish to brown, with males displaying bright blue patches on their throats and bellies, which are absent in females. The Slender Glass Lizard (Ophisaurus attenuatus) is unique as Tennessee’s only legless lizard, often mistaken for a snake. It can be identified by movable eyelids and external ear openings, features that snakes lack, and typically has a dark stripe down its back.
Green Anoles (Anolis carolinensis) are small, tree-dwelling lizards found in the southern half of the state, known for their ability to change color from brown to vibrant green. Males feature a distinctive pink or reddish throat fan, used in displays, distinguishing them from females who have a white throat. These lizards primarily feed on insects and spiders.
Where Lizards Thrive in Tennessee
Lizards thrive in Tennessee across various habitats, preferring warm, sunny environments due to their ectothermic nature. Woodlands and forests provide conditions where many species seek shelter under logs, leaf litter, and rocks. Open fields and grasslands are also common for basking and hunting insects.
Rocky outcrops and hillsides offer prime basking spots and crevices for refuge, supporting species like the Eastern Fence Lizard. Suburban gardens and backyards host lizards, especially in areas with woodpiles, fences, and debris that offer cover and foraging. Diverse habitats, including areas near water, sustain different lizard populations by providing necessary resources.
Observing Lizards Safely
Observing lizards in their natural environment can be a rewarding experience when approached responsibly. Lizards in Tennessee are generally harmless to humans. It is recommended to observe these reptiles from a distance to avoid causing them stress.
Attempting to catch or handle wild lizards can injure them; while their bites are typically non-venomous, they can be painful. Appreciating their contribution to the ecosystem supports local biodiversity. If a lizard is found indoors, gently encourage it to move outside, avoiding direct physical contact. Removing lizards from their natural habitats is not advisable, as it can disrupt their ecological balance.
