An emergent disease reduces survival of mature female eastern diamondback rattlesnakes ( Crotalus adamanteus ), a key demographic for a slow-lived species
While we failed to detect significant effects of reproductive covariates on female survival, this study was the first to document that severity of clinical signs of disease suggestive of ophidiomycosis is negatively associated with true survival of wild snakes. Annual...

Of the Midget Faded Rattlesnakes (Crotalus concolor) I've seen, which is a smaller number than I'd prefer, I think this is the best looking.

“Are you asleep great-grandfather? Or dead?” asked Hama hopefully, craning around to check when Duke Crotalus did not reply.

The old man was propped up by cushions in the duke’s seat breathing labouredly, dozing but disobligingly alive.

“How’s it taste?”

Ursur said nothing, and Crotalus reached out and grabbed his jaw, holding him there, watching very carefully as the blood dripped down from Ursur’s lip onto his own bare hand.

And he let go to taste it himself, right from the ether.

Illustration of a coiled rattlesnake (Crotalus adamanteus) with a thick body and distinct diamond-shaped patterns along its back. The snake's head is raised and slightly turned, showing detailed scales and facial markings. Its tail features a prominent segmented rattle, characteristic of rattlesnakes. The image is rendered in neutral tones on a plain background, emphasizing the texture and pattern of the snake's scales. The style reflects 19th-century scientific illustration focused on anatomical accuracy.

possibly the most beautiful rattlesnake you will ever see, a pink Huamantlan rattlesnake (Crotalus scutulatus salvini).

Found here in MX (In the states of Pueblo, Hidalga, Tlaxcala & Veracruz), it's truly stunning.
