Manatees, often called "sea cows," are large, gentle marine mammals that inhabit warm coastal waters and rivers. They are herbivores, primarily feeding on aquatic plants like seagrass and algae. Manatees can grow up to 13 feet long and weigh over 1,000 pounds. They are known for their slow-moving nature and friendly disposition. These animals are part of the order Sirenia, which also includes dugongs. Manatees have a streamlined body and paddle-like flippers, which help them navigate through water. They are vulnerable to threats such as habitat loss and boat collisions, making conservation efforts essential for their survival.
