I. DESCRIPTION:
  • Grows to approximately 16-25 inches in length.
  • Heavy-bodied, broad neck, spade-like upturned snout and enlarged teeth toward rear of upper jaw.
  • Base color IS pale brown, buff, or gray; large dark brown spots on back, smaller spots on sides; and "washed" black belly.
II. GEOGRAPHICAL RANGE AND HABITAT:
  • Ranges from southern Alberta and northwest Manitoba; south to southeast Arizona, Texas, and into northern Mexico; also Iowa, Minnesota, Illinois, Missouri, and Arkansas.
  • Sandy or gravelly prairies, open woodlands, farmlands, river floodplains, semi-desert habitats and mountain canyon bottoms.
III. DIET:
  • Toads, frogs, salamanders, lizards, snakes, turtles and reptile eggs.
IV. LIFE CYCLE/SOCIAL STRUCTURE:
  • Solitary; diurnal, i.e., active during the morning and evening.
  • Preyed upon by large birds and snakes.
  • Female lays clutch of 4-23 eggs underground from June to August; young are approximately 7 inches long at birth.
  • Life span is generally 15-18 years.
V. SPECIAL NOTES/ADAPTATIONS:
  • When cornered, flattens head and neck, and strikes with open mouth, hissing but seldom biting. If this behavior does not deter a threat, may also "play possum," suddenly turning belly up, writhing violently for a few moments, then lying still with its mouth open and tongue lolling. Also, the tail is often held near its head in a tight coil and excrement is discharged.
  • Burrower that uses its shovel-shaped snout for digging.
  • Enlarged rear teeth (or fangs) used to puncture the lungs of live prey, helping it to swallow; saliva believed to be toxic (although usually innocuous to humans).
VI. ENVIRONMENTAL IMPACT:
  • Helps keep rodent population in check.
VII. POPULATION STATUS:
  • Habitat destruction or other environmental changes may force it out of its natural habitat.
  • Protected by state law in some areas.
VIII. MORE HOGNOSE SNAKE FACTS:
  • The hognose's Latin name, Heterorodon, means "different tooth." This refers to the enlarged teeth in the rear of the mouth.
  • Also known as the "Puff Adder." A common folk myth states that a puff adder's breath is mixed with poison and can kill a person at a distance of 25 feet. Although the bite of a Hognose snake can produce swelling and a burning sensation, it rarely bites people and is not poisonous. It does puff itself up and hiss when threatened, but its breath is harmless.
