The term 'Young Rhino' can be broken down into two words, 'CALF' and 'Rhino'. A CALF is a young animal, usually referring to a young bovine such as a cow or bull. A rhino is a large mammal with thick skin and one or two horns on its snout. The young of this species is referred to as a CALF. The CALF of a rhino is typically born after a gestation period of 15-16 months and is dependent on its mother for the first few years of its life.
