At the time, Arnie was in quarantine as zoo officials acclimated the sloth and prepared his exhibit. Arnie is a Linnaeus’s two-toed sloth who came from the Biodome in Montreal, Sean Putney, chief zoological officer, said. The species hails from South America. Why is he named Arnie? “A generous, long-time Zoo donor has given him the moniker Arenal, named after a volcano in Costa Rica,” Romary said. “He will go by the nickname Arnie.” Putney said that, while they need to get used to taking care of one sloth for now, they are interested in finding a mate for Arnie in the future.
