Range: In Florida, the Coastal Dunes Crowned Snake occurs along the Atlantic coast from Brevard County south to Palm Beach County. It is not found outside of Florida.

Habitat: Rare, sometimes found in well-drained grassy dunes, pinelands, and hardwood hammocks.

Comments: HARMLESS (Non-Venomous). The Coastal Dunes Crowned Snake is a terrestrial burrower, mainly found under rocks, logs, leaf litter, and other debris. It feeds on insect larvae, snails, and centipedes. It lays eggs. No specific data have been reported, reproduction is believed to be similar to the Southeastern Crowned Snake (Tantilla coronata).

Comparison with other species: The Rim Rock Crowned Snake (Tantilla oolitica) lacks a lighter colored snout and scales on the upper lip. The Florida Brown Snake (Storeria victa) is grayish-brown with a light mid-dorsal stripe and flecking on each side. The Ringneck snake (Diadophis punctatus) is black with a bright yellowish-orange belly with black spots.
