are darker in color when they are very young. African manatees measure up to in length, and weigh about . African manatees are typically extremely slow, moving between 4.8 km and 8.0 km (3 and 5 mi) per hour, although when scared by predators they can travel at speeds of about per hour. The African manatee's large forelimbs, or flippers, are used to paddle and to bring food to its mouth. Vegetation is then chewed by the manatee's strong molars, which are its only teeth. When the manatee is born, each jaw has two vestigial incisors, which the manatee loses as it matures. If the African manatee's molars happen to fall out, new molars grow in their place. The manatee's flippers, which have nails, are also used to graze other manatees. The African manatee does not have any hind limbs. From the exterior, the African manatee looks very similar to the American manatee; however, the African manatee is different from the Amazonian manatee, which has characteristic white markings on its abdomen. Evolution and legends The West African manatee is a descendant of trichechids found in coastal South America during the Pliocene Epoch. Although they tend to stay in freshwater, theory suggests that, through transoceanic currents, the species reached West Africa during the late Pliocene. The West African manatee's appearance is thought to be the result of these currents and species movement. The African manatee's ancestors passed down advantageous migration and food traits. The African manatee is not restricted to a certain area, and does not have to rely heavily on only one ecosystem for support. This evolution of the African manatee's diversity may be part of its key attribute to survival. They are more diverse than other manatees due to their ability to survive in salt water, although they do need access to fresh water for drinking purposes. According to people of western Africa, Maame Water (also spelled Mami Wata), a recurring character in many coastal legends, is a goddess of the sea and a symbol of wealth and beauty. Maame Water also flips over canoes and entices their occupants to visit her kingdom. Scientists from the Institute of Aquatic Biology of the Centre for Scientific and Industrial Research (CSIR) and the Wildlife Department in Ghana have concluded that Maame Water is based on the West African manatee. According to Dr. Mamaa Entsua-Mensah, who performs research for CSIR, when female
