Giraffe Skin Disease is a disorder of the skin that is characterized by crusty lesions on the back side of the front legs of adult Masai giraffe (Giraffa camelopardalis tippelskirchi) the only subspecies in Tanzania. Lesions such as the ones shown in this picture on the forelimbs indicate Giraffe Skin Disease. Giraffe Skin Disease was first recorded 12 years ago in Ruaha National Park in central Tanzania. Since then, the disease has spread to parts of northern Tanzania, including Tarangire and Serengeti National Parks. Very little was known about how many giraffes have this disease, and how it affected their survival.
