The non-venomous snake is not dangerous to humans. When confronted by a predator, it puts on an elaborate threat display involving hissing, neck spreading, and playing dead. It even feigns striking but rarely bites.

Southern Hognose Snakes at a Glance

Southern Hognose Snake Range

Distribution

It lives on the coastal plain of the southeastern United States from North Carolina, west to Mississippi, and south to Lake Okeechobee in Florida.

Habitat

It occurs in open and dry sandy areas – in dry fields, river floodplains, and wire grass flatwoods.

Though the introduction of fire ants has been implicated in their dwindling numbers, some of the most potent causes are habitat loss, fragmentation, degradation, and road mortality.

Heterodon simus

Lifespan

Predators

They are eaten by the common kingsnake, eastern indigo snake, red-tailed hawk, and other carnivorous mammals and birds.

Diet

The southern hognose snake preys on frogs (especially Pseudacris ornata and Hyla gratiosa), toads, mice, and spadefoots.

Reproduction

Oviparous (lays eggs that hatch outside the body)

The mature adults mate from April to August. Whitish, thin-shelled, leathery eggs are laid in clutches of 6-14. They hatch after 55-60 days. Each hatchling is 6-7 in (15-18 cm) in total length.
