One Year has Passed Since the Debut Of the Triplet African Lion Cubs At the Wildlife Conservation Society’s Bronx Zoo! Nala, Shani, and Adamma stand with their father, M’wasi at the Wildlife Conservation Society’s Bronx Zoo. The three young African lions have grown to more than 150 lbs each since they made their public debut one year ago. The entire family can be seen in the zoo’s African Plains exhibit which opened 70 years ago this month.
