Conservation
Listed as Least Concern on the IUCN Red List due to its wide distribution and large population, though local populations face threats from habitat fragmentation and road mortality.
Physical Description
Characterized by an upturned, shovel-like snout used for digging. Coloration and pattern are extremely variable, featuring large dark blotches or spots on a gray, brown, yellowish, or reddish background, though some individuals can be entirely black (melanistic). Scales are keeled.
Size & Dimensions
Typical adults reach 50 to 84 cm (20 to 33 inches) in total length, with exceptionally large females reaching up to 115 cm (45 inches). The specimen in the image appears to be a juvenile or subadult.
Habitat
Favors areas with sandy soils, including open pine woods, fields, woodland edges, and coastal regions. Found from sea level up to moderate elevations.
Diet & Feeding
Diet specializes heavily on amphibians, particularly toads. They use their upturned snout to unearth buried toads and possess specialized enlarged rear teeth to deflate puffed-up toads.
Reproduction
Oviparous, laying clutches typically ranging from 4 to 61 eggs (average around 15-25) in sandy soil during June or July. Eggs hatch after an incubation period of approximately 60 days.
Conservation Status
Listed as Least Concern on the IUCN Red List due to its wide distribution and large population, though local populations face threats from habitat fragmentation and road mortality.
Cultural Significance
Famous for its dramatic theatrical displays, including flattening the head and neck, hissing loudly, striking with a closed mouth, and ultimately rolling over and playing dead (thanatosis) while releasing a foul-smelling musk.
Notable Features
Possesses a specialized rostral scale modified into a sharp, upturned plough used for digging up prey and burrowing into sandy substrates, alongside a remarkable behavioral repertoire centered around bluffing and mimicking vipers.
