The Tulsa Zoo on Monday announced the hatching of nine Aldabra tortoises, becoming the first zoo to successfully breed the species more than once.
The hatchlings began to cut through their shells Feb. 9, after a 3-4 month incubation period, the zoo said in a news release. Hatchlings typically take up to five days to fully emerge from their shells, and they stay in an incubator for an additional 2-3 days before being placed in an exhibit, the zoo said.
The Tulsa Zoo is home to three adult male and two adult female Aldabra tortoises. The males weigh nearly 400 pounds each, and the females weigh about 175 pounds each.
