In this Aug. 31, 2010 photo, Inge, a black rhinoceros at the Cleveland Metroparks Zoo, receives a gentle nuzzle from her yet-to-be-named daughter as Inge feeds in the rhino house at the zoo, in Cleveland. The yet-to-be-named baby rhino born on August 17 weighed near 65 lbs. at birth and will gain 3-4 lbs. a day until she is 6 months old. Black rhinos, native to Africa, are the most endangered of the five rhino species, with only about 3,000 in the world.
