Latin Names...
Hello Brian.
I think I can offer some help in putting names to the faces of these guys. The first looks to be a very nice example of Crotalus
cerastes cerastes. The "Mojave" sidewinder. This species includes three sub species of which the "Mojave" is considered the nominate form. The other sub species are Crotalus cerastes laterorepens... the "Colorado" sidewinder and Crotalus cerastes cercobombus...the "Southern" sidewinder. These guys are found in deserts consisting of loose sands and rocky outcrops {used for cover etc.}. They are a small species of rattlesnake and rarely exceed 30" in adult length. As a matter of fact I recall a male I kept for 6 yrs. {and he fathered 3 litters} at the "gi-normous" size of 19"!
Anyway, these usually make for interesting captives, however some may insist on lizards as a food source. And believe me, baby "sandsliders" are delicate and fustrating to try and switch 'em to mice pinks. Man are the babies small!
The other "Rattler" looks to be a "Banded rock" rattlesnake. A.K.A. Crotalus lepidus klauberi. These guys are a beautiful species of which there is 1 other sub species {Crotalus lepidus lepidus}. Again, a smaller species with adults usually growing to 36" max. I have not kept the nominate form {the one you posted} but I have kept numerous specimens of the "Mottled" rock rattlesnake. I found these to be very content captives that would reproduce well and I really liked working with these snakes. Anyhow... hope I've helped and if you would like some more info let me know or cruise the net as there should be a good supply of info on these guys. Good luck and stay safe! Cheers!
