The Masai giraffe (Giraffa tippelskirchi), also spelled Maasai giraffe, also called Kilimanjaro giraffe, is the largest species of giraffe and the tallest land mammal. It is found in Kenya, Tanzania, and Zambia. Once considered a subspecies of the conglomerate Giraffa camelopardalis species, recent studies identified the Masai giraffe as a separate species of a reorganised Giraffa genus. The Rhodesian giraffe (formerly G. c. thornicrofti) was once considered a separate subspecies, but after genetic analysis it has been subsumed as an ecotype into the Masai giraffe species. Overall, the approximate number of all populations accumulate to 32,550 in the wild, with 550 being of the Rhodesian phenotype.
