The corn snake (Pantherophis guttatus), sometimes called the Red Rat Snake is a species of North American rat snake in the family Colubridae. The species subdues its small prey by constriction. It is found throughout the southeastern and central United States. Though superficially resembling the venomous copperhead (Agkistrodon contortrix) and often killed as a result of this mistaken identity, the corn snake lacks functional venom and is harmless to humans. The corn snake is beneficial to humans because it helps control populations of wild rodent pests that damage crops and spread disease.
The corn snake is named for the species' regular presence near grain stores, where it preys on mice and rats that eat harvested corn (maize). The Oxford English Dictionary cites this usage as far back as 1675, whilst other sources maintain that the corn snake is so-named because the distinctive, nearly-checkered pattern of the snake's belly scales resembles the kernels of variegated corn.
The genus name Panthērophis literally means "panther snake" in reference to the snake's panther-like skin pattern; from Ancient Greek: πάνθηρ : pánthēr "panther", and Ancient Greek: ὄφις : óphis... Wikipedia →
