The St. Louis Zoo welcomed an adorable baby black rhinoceros calf, Moyo, just a few days ago. His name means "heart" in Swahili. Moyo is being cared for by his mother, Kati Rain, and father, Ajabu, and he clearly enjoys it when zookeepers scratch his nose with a brush. Babies usually weigh 80-100 pounds at birth. Moyo could grow to weigh 3,100 pounds, which is about as heavy as a car. There are only about 5,000 black rhinos left worldwide and the species is critically endangered.
