These gentle giants are dependent on seagrass beds for food, which is why their habitat is closely associated with these marine plant ecosystems.

Dugongs can be found in warm coastal waters, coral reefs, and estuaries from East Africa to Australia, including the Red Sea, Indian Ocean, and Pacific Ocean. They are considered vulnerable to extinction due to habitat loss, poaching, and accidental entanglement in fishing nets.

It is important to protect dugongs and their seagrass habitats to ensure their survival and the overall health of these marine ecosystems.

Diet and Behavior of Dugongs

Diet and Behavior of Dugongs

Dugongs are gentle herbivores that use their strong upper and lower lips to feed on seagrass. Their diet is mostly comprised of sea grass and algae which they search for with their sensitive flippers.

Dugongs are fairly solitary animals and usually only come together during mating. They are also known to sometimes form small groups in search of food. Let’s further explore their diet and behavior.

Feeding habits and diet preferences

Dugongs are gentle, herbivorous marine mammals that graze on seagrass and other aquatic plants. They have a unique feeding habit and diet preference that helps sustain their lives in the sea.

Here are some insights into their feeding habits and diet preferences:

  • Dugongs feed primarily on seagrass, which makes up to 90% of their diet. They eat around 40-50 kilograms of seagrass per day, which can be about one-tenth of their body weight.
  • Apart from seagrass, they occasionally eat other aquatic plants, such as marine algae and mangrove fruits.
  • They have a grazing pattern that allows them to consume seagrass without uprooting it from the seabed.
  • They are known to live in areas with shallow, clear and warm water where seagrass is abundant. Dugongs help maintain the health of seagrass beds, which in turn provide a habitat for many other marine species.

Social behavior and communication

Dugongs are known for their impressive social behavior and communication skills, which play a significant role in their survival and interaction with other sea creatures.

  • Dugongs communicate through vocalizations, such as chirps, whistles, and bellows, which allow them to navigate and locate food sources. They also use these sounds to interact with each other and establish their territory.
  • Furthermore, the diet of dugongs plays a crucial role in their behavior. They primarily feed on seagrass, which requires them to spend a considerable amount of time grazing in shallow waters. This dietary restriction affects their social behavior, as dugongs often congregate in large groups in areas where seagrasses are abundant.

Overall, the social behavior and communication skills of dugongs are vital to their survival and play a significant role in maintaining a healthy ecosystem in marine environments.

Reproduction and life cycle

The reproduction and life cycle of dugongs are critical to understanding these gentle giants of the sea.
