The blue-tailed skink, scientifically known as Plestiodon skiltonianus, is a small lizard commonly found in North America. It is easily recognizable by its vibrant blue tail, which is particularly striking against its brown or gray body. These lizards typically inhabit grassy areas, forests, and gardens, where they can often be seen basking in the sun. Blue-tailed skinks are known for their ability to lose their tails when threatened, a defense mechanism that allows them to escape predators. They primarily feed on insects and other small invertebrates. As they mature, their bright blue tails may fade, but they remain an important part of their ecosystem.
