Conservation
Listed as Least Concern on the IUCN Red List, though populations face local declines due to habitat fragmentation, intentional killing, and decline in primary prey sources.
Physical Description
Features a stout body with strongly keeled scales, a distinctive upturned snout used for digging, and bold dark blotches or crossbands over a background of gray, brown, olive, or reddish-yellow. The neck can flatten into a hood-like display when threatened.
Size & Dimensions
Typical adults range from 51 to 115 cm in total length, with females generally growing larger than males. The visible specimen appears to be a medium-sized adult.
Habitat
Prefers open woodlands, sandy fields, agricultural areas, coastal dunes, and brushlands with loose, sandy soil suitable for burrowing and excavating.
Diet & Feeding
Specialized feeder focusing primarily on amphibians, particularly toads, using its upturned snout to unearth them and enlarged rear teeth to deflate puffed-up prey.
Reproduction
Oviparous species that mates in spring and deposits clutches averaging 15 to 25 eggs in underground nests excavated in sandy soil during early summer.
Look-alikes
Frequently confused with various viper species due to its thick body, dark blotches, and defensive head-flattening behaviors, but easily distinguished by its upturned rostral scale.
Conservation Status
Listed as Least Concern on the IUCN Red List, though populations face local declines due to habitat fragmentation, intentional killing, and decline in primary prey sources.
Cultural Significance
Famous for its elaborate theatrical defensive displays, including playing dead (thanatosis) by rolling onto its back and emitting a foul musk.
Notable Features
Possesses a specialized upturned rostral scale on the snout and an exceptional behavioral repertoire for bluffing predators, including hissing, flattening the neck, striking with a closed mouth, and feigning death.
