Western Skinks are common reptiles found across various regions, frequently encountered in gardens and natural habitats. People often wonder if these small, smooth-scaled lizards pose any threat, particularly regarding whether they are poisonous or venomous. This concern stems from general misconceptions about reptiles and their defense mechanisms.
Are Western Skinks Poisonous?
Western Skinks (Plestiodon skiltonianus) are neither poisonous nor venomous. They do not produce toxins harmful to humans. An animal is poisonous if it causes harm when ingested or absorbed, like certain frogs or mushrooms. In contrast, an animal is venomous if it injects toxins, typically through a bite or sting, like a snake or a spider.
Skinks lack venom glands and do not possess fangs or stingers for injecting toxins. While they have small teeth and might bite if they feel threatened or are handled, their bite is harmless to humans and causes no significant damage. These lizards primarily rely on fleeing or other defense mechanisms, such as dropping their tail, rather than chemical defenses.
Identifying Western Skinks
Western Skinks are identifiable by their sleek appearance and distinctive markings. They have smooth, shiny scales and relatively short legs, giving them a somewhat snake-like movement. Adults typically measure between 100 to 210 mm (about 4 to 8.25 inches) in total length, including their tail.
A broad brown or black band runs along their sides, extending from the head past the hind legs. They also feature whitish to beige stripes that begin at the nose, extend over the eye, and run along the body onto the tail. Younger Western Skinks are notable for their vibrant blue tails, a color that fades to gray or brown as they mature. These lizards prefer habitats with loose soil for burrowing, such as grasslands, open woodlands, and rocky areas, from sea level up to 2,130 meters (7,000 feet).
What to Do When You Encounter a Skink
Western Skinks are naturally shy and secretive creatures that will typically try to escape when approached. Observing them from a distance is the best approach to avoid startling them. They are beneficial for gardens as they consume various invertebrates like spiders, beetles, and crickets.
If a Western Skink accidentally enters a home, it can be gently guided back outside. One method involves placing a container over the skink and sliding a piece of cardboard or paper underneath to safely capture and relocate it. Sealing gaps around doors and foundations can help prevent them from entering indoor spaces. These lizards pose no threat to humans or pets and are harmless to have around.
