Family

Order: Squamata, Suborder: Serpentes, Family: Colubridae, Subfamily: Dipsadinae, Genus: Heterodon, Species: Heterodon platirhinos

Conservation

IUCN Status: Least Concern, though localized populations are threatened by habitat loss, road mortality, and persecution due to their resemblance to venomous snakes.

Physical Description

Highly variable coloration (melanistic, gray, or patterned as seen here). Characterized by a distinctive upturned 'hog-like' snout (rostral scale). This specimen shows a series of dark dorsal blotches on a lighter background; the head is broad and thick, and scales are heavily keeled.

Size & Dimensions

Specimen appears to be an adult around 60-80 cm. Typical adult size is 50-115 cm in total length.

Habitat

Found in various habitats with sandy or loose soils, including open woodlands, pine forests, coastal dunes, and fields. Prefers areas that allow for easy burrowing.

Diet & Feeding

Amphibian specialist, primarily feeding on toads (Bufo/Anaxyrus). They possess enlarged rear teeth to puncture inflated toads and have specialized adrenal glands to counteract toad toxins.

Reproduction

Oviparous (egg-laying). Females lay clutches of 8-40 eggs in early summer, which hatch in late summer or early fall after about 60 days.

Look-alikes

Frequently confused with the Timber Rattlesnake (Crotalus horridus) or Copperhead (Agkistrodon contortrix) due to color and hissing. Distinguished by the upturned snout and lack of a rattle or heat-sensing pits.

Conservation Status

IUCN Status: Least Concern, though localized populations are threatened by habitat loss, road mortality, and persecution due to their resemblance to venomous snakes.

Cultural Significance

Commonly known as the 'Puff Adder' or 'Spreadhead' in American folklore. Valued by gardeners for controlling amphibian populations and by hobbyists for their unique behaviors.

Notable Features

The upturned rostral scale used for digging up buried toads and the physiological ability to neutralize Bufotoxins, which are lethal to most other predators.
