The term 'Dugong Relative' is referring to the Manatee, which is a large aquatic mammal that is related to the Dugong. Manatees are found in shallow, warm coastal waters and rivers of the Atlantic Ocean, Caribbean Sea, and Gulf of Mexico. They are herbivores and feed on sea grasses and other aquatic plants. Manatees are known for their slow, gentle nature and are considered a vulnerable species due to human activities such as boat strikes and habitat destruction.
