North Carolina to south Florida and west to Louisiana (isolated records exist of its occurrence in Oklahoma and Missouri)
Adults grow to 18 – 42.5 in. (46-108.3 cm) in length, although the head-body length is only 12 in. (30.5 cm) at most. There are 98 or more scales along the lateral groove. In this species, no dark longitudinal stripes are present below the lateral groove or under the tail, and there is no distinct mid-dorsal stripe. The neck is marked with a series of mostly vertical, or highly irregular, white marks. White markings on posterior corners of scales. Dorsally, older specimens have a pattern consisting of numerous longitudinal dark lines or dashes. Occasionally, similar parallel lines cover the entire mid-dorsal area. Older adults may be greenish above and yellow below; this is the only Ophisaurus species that may have a greenish appearance. Juveniles are khaki-colored and usually have two dark stripes that run down the back.
