Not all hognose species are known to play dead. This unique trait is found in Heterodon species which are found in North America. North American hognose snakes are dramatic and short creatures. When spotted, they often go limp and play dead. They even let their tongues hang outside their mouths like true actors worthy of Oscars.

Hognose Snake Venom

Although hognose snakes have venomous saliva, it is only fatally dangerous to their prey. Their salivas are known to be mildly toxic but since they do not inject this saliva in any way, the damage they can inflict is minimal. Their saliva mainly helps them when swallowing their prey. They are not known to use their toxic saliva to kill.

Generally, hognose snakes have sand-brown colors. They also have markings that could be a wide range of colors such as black, white, red, green, orange, and brown. Their markings usually depend on their locality.

Length-wise, the species vary. They generally aren’t long and measure from 2 feet to 4 feet on average.
