Comments: HARMLESS (Non-Venomous) and it rarely bites when handled. When startled or threatened, it may coil and raise the tail displaying its brightly-colored underside. It may emit a strong smelling musk from the glands just inside the cloaca.

The Southern Ringneck Snake is a terrestrial burrower, frequently found in or underneath logs or other debris. It feeds on small earthworms, slugs, frogs, anoles, geckos, skinks, snakes, and salamanders.

It lays eggs. During the summer usually 2-8 whitish eggs are laid in moist areas such as underneath or inside rotting logs. Sometimes a communal nest site may be used by several different females. Newborns are 3-4 inches (7.6-10 cm).

Ringneck Snakes are the most frequently found snakes in Florida swimming pools — they crawl in to get a drink and then cannot climb out because they are too small to reach the lip of the pool. If you find one in your pool, lift it out with the leaf skimmer or a dipnet and turn it loose in the shrubs where it can get back to eating things you do not want in your garden.

Comparison with other species: The Key Ringneck Snake (Diadophis punctatus acricus) has a slate gray colored body and an indistinct or missing neck ring. The Florida Brown Snake (Storeria victa) has a light colored stripe down its back, flecking on its sides, and a distinct brown spot under the eye.
