Do rattlesnakes and bull snakes cross breed? #142780

Asked July 23, 2013, 11:07 PM EDT

About 10  years ago I read an article in a local paper about the cross breeding of rattle and bull snakes at C.S.U..
The bull looking snakes had the venom of a rattler.
Is this true?

Expert Response

It is NOT true that these snakes can mate and create hybrids that are half bullsnake and half rattlesnake and poisonous like a rattlesnake. These snakes are different species and therefore cannot breed with one another.
