I just wanted to add some information...for anyone that might care...
Pacific Rattlesnakes, like the Southern one TandJ posted to start this thread, were seperated from Western Rattlesnakes several years. Western rattlesnakes were classified as
Crotalus viridis and included Northern and Southern Pacific, Great Basin, Prairie, Hopi, Grand Canyon, and a couple other subspecies of rattlesnake (
C.v. oreganus, C.v. helleri, C.v. lutosus, C.v. viridis, C.v. nuntius, C.v. abyssus).
This HUGE complex of rattlesnakes was seperated a few years ago into Western rattlesnakes (
Crotalus viridis) and Pacific rattlesnakes (
Crotalus oreganus), and some were elevated to full species status. The main seperation of species was the impassable Rocky Mountains, which clearly delineated the new
oreganus complex from the existing
viridis complex, making seperation not only fairly easy...but pretty straight forward. Until this year...
Currently, the snake which started this thread, a Southern Pacific, is classified as
Crotalus oreganus helleri, not
Crotalus viridis helleri. However...that will change again next year. All three subspecies of the oreganus complex are being elevated to ful species status. By 2010, Pacific rattlers will be classified as Northern Pacific--
Crotalus oreganus, Southern Pacific--
Crotalus helleri, and Great Basin--
Crotalus lutosus. In other words...they are no longer sub-species of the Pacific Complex, but rather, each wil be classified as a compeltely seperate and distinct species. This is due to locality data, mtDNA research, and other factors which have proven that these snakes are not as closely related as they were once thought to be.
Not that any of this is important...just interesting (at least to me) tidbits regarding the taxonomy of Western and Pacific rattlesnakes over the last 10 years...
Either way...that's still a gorgeous Southern Pacific...and I still want a Black Tail rattler...
