I read that skinks are generally carnivorous and largely eat insects including crickets, grasshoppers, beetles, and caterpillars. They also eat earthworms, slugs, and snails. Raccoons, foxes, possums, snakes, crows, cats, dogs, herons, hawks, and kookaburras all are predators of skinks. I've also been told that skunks love skinks. This guy was sunning on the front porch this afternoon. Wonder who else I'll see.
