Conservation
IUCN Red List status is Least Concern, though localized populations face threats from habitat fragmentation, road mortality, and intentional killing due to mistaken identity.
Physical Description
Features a distinctive upturned snout used for digging, a thick body with keeled scales, and highly variable coloration ranging from yellowish, tan, grey, brown, to olive, marked with dark blotches down the back and sides. Head is slightly widened with dark stripes behind the eyes.
Size & Dimensions
The pictured specimen appears to be a juvenile, roughly 8 to 12 inches long. Adults typically reach 20 to 30 inches, with a maximum recorded length of about 45 inches.
Habitat
Prefer areas with sandy soils, including open forests, pine barrens, fields, coastal areas, and agricultural edges, typically from sea level to moderate elevations.
Diet & Feeding
Specialized diet consisting primarily of amphibians, especially toads. They use an active foraging strategy and possess specialized rear teeth to deflate toads that inflate in defense.
Reproduction
Oviparous species, females lay clutches averaging 15 to 25 eggs, sometimes up to 40, in underground nests dug into sandy soil during early summer.
Look-alikes
Frequently confused with various rattlesnake species due to its defensive displays and dark blotched pattern, but easily distinguished by the lack of a rattle, absence of heat-sensing pits, and the upturned snout.
Conservation Status
IUCN Red List status is Least Concern, though localized populations face threats from habitat fragmentation, road mortality, and intentional killing due to mistaken identity.
Cultural Significance
Famous for elaborate theatrical defensive displays, including flattening the neck like a cobra, hissing loudly, rolling over, and playing dead (thanatosis), which often leads to local folklore names like 'puff adder' or 'hissing viper'.
Notable Features
Possesses a modified rostral scale that forms a sharp, upturned plough on the snout, perfectly adapted for excavating buried amphibians and burrowing in loose sand.
