The term 'Dugongs' Cousins' refers to the Manatees, which are large aquatic mammals that are closely related to the Dugong. Manatees are found in shallow coastal areas and rivers of the Caribbean Sea, the Gulf of Mexico, and the Amazon River. They have a large, rounded body with two flippers and a paddle-shaped tail. Manatees are herbivores and feed on sea grasses and other aquatic plants. They are considered an endangered species due to human activities such as fishing, boat collisions, and habitat destruction.
