Snake Facts


Thesmallest snake in Illinois is the flathead snake. The longest Illinois specimen measures eight inches (20.3 cm).
The largest Illinois snake is the bullsnake (Pituophis melanoleucus), with the Illinois record length at seven feet, two inches (218.5 cm).
A snake can swallow prey that is three times larger than the size of its own head.
Snakes are very efficient rodent controllers. Large and medium-sized snakes can eat up to nine pounds of rats and mice per year. That amount of rodents could fill a king-sized pillowcase!
Females of some snake species can store sperm for as long as five years inside their body.
Snake scales and rattlesnake rattles are made of keratin, a hard protein also found in the hair, fingernails, and hooves of other animals.
Snakes have four rows of teeth in the top of the mouth and two rows on the bottom of the mouth.
Rattlesnakes add a new segment at the base of the rattle each time the snake sheds its skin. Old segments at the tip may disintegrate or break off.
Kingsnakes are immune to the venom of copperheads, cottonmouths, and rattlesnakes.
When threatened, a hognose snake spreads its head and neck, somewhat like a cobra would, then rolls over and plays dead if it continues to be disturbed.
