In my experience eastern diamondbacks are less aggressive than canebrakes. When one coils up at your feet and you freeze or step away, it will usually back away itself by lifting one coil over another until it feels a safe distance away from the threat, then uncoil and crawl away.

Of course they're big and carry a lethal load of hemotoxin but unless attacked by a dog are not as sure of striking as the canebrake. Water moccasins on the other hand are always bad news...Geo
