The dugong is easily distinguishable from the manatees by its fluked, dolphin-like tail; moreover, it possesses a unique skull and teeth. Its snout is sharply downturned, an adaptation for feeding in benthic seagrass communities. The molar teeth are simple and peg-like, unlike the more elaborate molar dentition of manatees.
Dugongs are large marine mammals often called sea cows due to their herbivorous diet and slow, gentle nature. They are related to both manatees and—surprisingly—elephants. They live in warm coastal waters from East Africa to Australia, grazing on underwater grasses as their main food source.

3. Dugongs have been nicknamed “sea cows”
Known to graze on sparse seagrass patches, dugongs are often called “sea cows”. They prefer grass that is high in nitrogen content and low in fiber, making it easier to break down. Most graze all day. They are also sometimes called ‘sea pigs’ and ‘sea camels’.

- They aren’t in the same family. Manatees and dugongs may be of the same order, but they are not of the same family classification. Manatees are members of the Trichechide family, and dugongs are members of the Dugongidae family.
- Manatees are larger. Dugongs and manatees are similar in size, but the fact of the matter is that manatees can grow to be much larger than dugongs. Dugongs grow up to nine feet in length, while manatees can grow up to thirteen feet in length.
- They live in different parts of the world. These two animals are found in different regions of the world. Dugongs are found throughout the Red Sea, Indian Ocean, and the western Pacific Ocean.
- Different snouts. One of the most significant differences between the dugong and the manatee is their snouts. Dugongs have long, narrow snouts with thick vibrissae, or mustaches, that grow on their upper lips and chins.
