This guy was parked in an EV spot!

In OK, we have 7 poisonous varieties:

Copperhead
Western Cottonmouth
Timber Rattlesnake
Prairie Rattlesnake
Western Diamond-backed Rattlesnake
Western Massasauga Rattlesnake
Western Pygmy Rattlesnake

Being an avid outdoors person, I can recognize each by sight. The fun part is we have several that look and act very similar to these. They're all very beneficial. I've only seen a couple of the non-venomous types in town.

 

We don't have the sidewinder?

We do, plus a few others.
I assume the list is only for @Mark57 location.

 

Correct, those were for Oklahoma only. Every state is different.

For @bwilson4web and his sidewinder's, they are desert snakes. IE, lifting their body off the hot earth by sidewinding in CA, NV, UT, and AZ.

 

I find the Mohave rattlesnake interesting. There are two populations. One has a hemolytic venom, and the other a neurotoxic one. Where the populations overlap, an individual can have both.

 

They are interesting and benificial, though I don't expect to be hugging any of them anytime soon.

 

Jerry Closer tells about the time he went to Sweetwater Texas for the annual rattle snake round-up. They had an above ground pool full of rattle snakes. They fetch one, milk the venom, and then cut off their heads with an ax. They'd dress them out, roll them in flower, and fry them up to a long line of people paying $1 per plate. One time, they had someone from the Society for the Prevention of Cruelty to Animals there to make sure they were killin' in a humane way.

Jerry asked,"How can you kill a rattle snake any other way?"

Bob Wilson

 

In the regions where these round ups take place, the snakes are becoming less likely to rattle a warning before biting.
