In terms of category, the dugong belongs to the Chordata class Mammalia, so it belongs to vertebrates and mammals.As vertebrates, dugongs have a backbone, which distinguishes them from invertebrates.As a mammal, dugong is a relatively advanced animal, their breathing and reproductive methods are in line with the key characteristics of mammals, that is, to breathe with lungs, and to reproduce by viviparous means, as well as a period of lactation.
From the point of view of feeding habits, dugongs are herbivorous animals.Because dugongs live mainly in the sea, what they eat is some marine plants that grow at the bottom of the sea bed.They can eat many parts of these marine plants, roots, stems, leaves, and sometimes the whole plant.From the point of view of living environment, dugongs mainly live in the sea, but sometimes with the tide to the estuary activities, but will soon return.From the point of view of body size, dugong is larger, the average body length can reach 2.7 meters, many dugong individuals can reach more than 3 meters.
As mentioned above, dugongs are relatively large in size, larger than many animals in the ocean, so natural enemies are relatively few.Their natural enemies are sharks, killer whales, crocodiles and so on, but the actual dugongs killed by them are not particularly large.The dugong's greatest natural enemy is human.At present, dugong is an endangered animal, the number is very small, human hunting is an important reason for this phenomenon.
