The pictures are some south American Hognose Snakes that captured by the adventurer/animal trainer and he held it in his hands, there we can see the south American Hognose Snake shape is, and in the video below is a south American Hognose Snake staying in the land which gets caught by someone in the street.
In the video we can see that American Hognose Snake has little unique behavior, yes it raised it's tail little up, just like diamondback rattlesnake, and it's the opposite of cobra snake behavior that like raising her neck and head. But I don't have some information concerning it's intention doing this, whether he want to attack or just defend him self when threatened.
