Conservation
IUCN Status: Least Concern. Populations are globally stable but can be locally threatened by habitat loss and the decline of amphibian prey.
Physical Description
Variable in color, featuring a stout body with a distinctive upturned 'hog-like' snout. Patterns include patches of brown, gray, or tan, but solid black individuals occur. The pupils are round.
Size & Dimensions
Typically ranges from 50 to 80 cm (20 to 30 inches), with maximum lengths reaching 115 cm (45 inches). This specimen appears to be an average-sized adult.
Habitat
Found in areas with sandy or loose soils including woodlands, fields, and coastal areas; prefers habitats that facilitate burrowing and support toad populations.
Diet & Feeding
Specially adapted to eat toads. They use their upturned snout to dig for prey and specialized rear fangs to puncture and deflate toads that have puffed up defensively.
Reproduction
Oviparous (egg-laying), typically producing clutches of 8 to 40 eggs in early summer, which hatch in late summer or autumn.
Look-alikes
Often confused with Rattlesnakes (Crotalus) or Copperheads (Agkistrodon) due to their stout body and defensive behavior. Distinguished by their upturned snout and round pupils.
Conservation Status
IUCN Status: Least Concern. Populations are globally stable but can be locally threatened by habitat loss and the decline of amphibian prey.
Cultural Significance
A favorite among herpetologists for its dramatic displays; acts as an important ecological control for toad populations and an indicator of healthy sandy-soil ecosystems.
Notable Features
Famous for its elaborate 'zombie' act where it rolls over, hangs its tongue out, and may even emit a foul musk to mimic a rotting corpse to deter predators.
