The 1-year-old "male lion" at Sapporo Maruyama Zoo was actually a "female". The zoo plans to return Clay to the zoo in Ehime Prefecture, where he was born.

A blood test revealed that it was female. Clay will be returning to Tobe Zoo in the future. The zoo would like to make every effort to display male lions. "Up until now, there has been no difference in the breeding method for males and females at this stage of growth," said Kotaro Hayashi.
