LA Zoo works with Arizona museum and Texas zoo to save threatened rattlesnake

The Los Angeles Zoo is working with the Arizona-Sonora Desert Museum and San Antonio Zoo in an effort called the Project Obscurus that aims to help recover the New Mexico ridge-nosed rattlesnake — a species that is federally threatened.

Formally known as the Crotalus willardi obscurus, the snakes are critically endangered, so in August a group of 40 conservation experts met in Mexico to launch breeding efforts at the Los Angeles Zoo, San Antonio Zoo and Arizona-Sonora Desert Museum.

Each of the three zoos collected 10 specimens during the first phase of a breeding program that Rattlesnake Conservancy says will “be aimed at bolstering and diversifying the genetics of the U.S. populations of this rattlesnake through selective managed breeding and eventual release of offspring into their native habitat.”

“I am incredibly proud of the collective commitment to this project,” said Tony Daly-Crews, Project Obscurus director at the Rattlesnake Conservancy based in Florida in a prepared statement. “This is the largest assisted migration effort ever undertaken for a rattlesnake species, and I believe it will be pivotal in recovering the U.S. population.” Florida has a native population of rattlesnakes include the Eastern Diamondbacks.
