MIAMI-DADE COUNTY, Fla. – A black rhinoceros at Zoo Miami celebrated a milestone birthday Friday morning.

Toshi turned 43 this week, making him the oldest male black rhino in the country.

Zoo staff and volunteers gathered to sing Toshi happy birthday and present him with some of his favorite treats, as well as a specially baked cake. He also received specially prepared ice blocks with frozen fruits and vegetables strategically positioned within them to spell his name and announce his age.
