Rattlesnake

Timber rattlesnakes are highly venomous, but most are not likely to bite.

Timber Rattlesnakes

The gopher snake is commonly misidentified as a Rattlesnake because of its markings and defensive behavior. It may hiss loudly, flatten its head, vibrate the tail, and strike when annoyed.

Rattlesnake bites can be dangerous but are very rarely fatal to humans. With proper medical treatment, including antivenin, bites are usually not serious.
