“We also lost breeding programs for several endangered and threatened species,” she added. “It is especially difficult for our herpetologists who have dedicated their careers to caring for and advocating for these animals.”
Three critically endangered species died; the Louisiana pine snake, the Catalina Island rattlesnake and the Aruba Island rattlesnake. The zoo’s forest cobra and albino Eastern diamondback rattlesnake also died.
"We don't know exactly what occurred to cause this terrible event, but we do know it was isolated to a single building," the zoo said in a post on Facebook. "We are continuing to investigate all the physical systems and conducting necropsies to see if we can gain any insight."
