Rattlesnakes are most famous for their rattles, which are located at the tips of their tails. The rattle is used as a warning device when threatened with being stepped on or predated.
Hognose snakes are stout-bodied, sluggish, rear-fanged snakes. Their venom is mild and not dangerous to humans and their most distinguishing feature is their upturned snout for which they are named. This upturned snout aids them in digging in the loose sandy soil habitats in which they live.
