Despite being legally protected in many countries, the main causes of population decline remain anthropogenic and include fishing-related fatalities, habitat degradation, and hunting. With its long lifespan of 70 years or more and slow rate of reproduction, the dugong is especially vulnerable to extinction.
Found in groups of either mother and calf pairs or up to 200 animals, dugongs are semi-nomadic and may spend a considerable time journeying to find specific seagrass beds. The eyesight of the dugong is poor, with the animal relying on other senses to create a mental map of their surroundings.

May 10, 2022 · Dugongs making moves of > 15 km (up to 67 km) were also reported in habitats that are much more spatially constricted, such as small tropical lagoonal systems (de Iongh et al. 1998; Cleguer et al. 2020). Dugongs have been known to undertake long-distance movements across deep ocean trenches.
The Migration Pattern of Dugong. From what researchers have learned, dugongs move from the north coast of Indonesia and migrate towards Manado and Tana Toraja. After that, they return to parts of eastern Indonesia, such as Bintan Island, Seram Island, Temate Island, and the Anambas Islands.
Basic facts about Dugong: lifespan, distribution and habitat map, lifestyle and social behavior, mating habits, diet and nutrition, population size and status.
Unfortunately, dugongs are listed as vulnerable or endangered in many parts of their range due to various threats, including habitat loss, pollution, entanglement in fishing nets, and boat strikes. Dugongs hold cultural significance for many indigenous communities in regions where they are found.
