A Siberian tiger held in captivity at the Greater Vancouver Zoo has been found dead in her enclosure from unknown causes. According to her keepers, the young tiger, named Hani, appeared to be in good health -- though she stopped eating the day before and had begun acting abnormally.
Hani was less than a month shy of her third birthday. The median life expectancy for female Siberian tigers in captivity is 14 years old.
"All staff and volunteers at the zoo are devastated by Hani's sudden passing," the zoo said in a statement. "We are hopeful that the full necropsy that will be performed later today will provide some answers."
