A thick-bodied snake with an upturned snout, the hognose snake is extremely
variable in appearance. Generally a well-patterned snake, its background
color can be yellow, gray, pinkish brown, olive or black, patterned
with large rectangular spots down the middle of the back alternating
with dark spots on each side. Occasionally the pattern is obscured by
overall dark coloration. Individuals of this species may appear all
black. Body scales are keeled and the
underside of the tail is usually lighter than the rest of the belly.
Most matings take place in the spring. Females typically deposit 15-25 eggs
in a depression under rocks or logs, in sandy soil, or in mulch piles.
Eggs deposited in June and July hatch in August and September.
Sandy soils are an essential habitat characteristic for hognose snakes. These
snakes can be found in sandy woodlands, fields, farmland and coastal
areas. Toads are their preferred prey, although frogs, salamanders,
small mammals, birds and invertebrates are also taken. Hognose snakes
appear to be immune to poisons produced by toads, and are equipped with
large teeth in the back of their mouths, apparently to puncture inflated
toads so that they may be more easily swallowed. Many of these harmless
snakes are killed by people who are convinced that they are venomous
and dangerous. When confronted, the hognose snake will suck in air,
spread the skin around its head and neck like a cobra, hiss, and lunge
as if to strike. Despite this rather convincing show, hognose snakes
almost never bite. They will often feign death if provoked enough.
