Dugong Behavior

Dugongs, scientifically known as the Dugong dugon, are an ancient species of marine mammals found throughout the waters of the Indo-Pacific region.

They are closely related to manatees and are often referred to as ‘sea cows’ due to their grazing habits.

Despite being a largely mysterious species, studying their behavior has been a priority in recent years due to their declining population.

1. Dugong Description

Dugongs are large marine mammals found throughout the eastern and western Indian oceans. They have bulky bodies with large tail fins and flippers on each side of their bodies.

Their front flippers are used to steer while swimming, while their back flippers propel them through the water.

With an average length of 3 meters (9 feet) and a weight between 200-400 kilograms (440-880 lbs), dugongs are one of the largest herbivorous animals in the ocean.

The coloration of dugongs ranges from grey to brownish grey and they have sparse bristles that cover their entire body.

The tail is often lighter than the rest of its body and has horizontal stripes on it for added camouflage in its environment.

2. Dugong Habits

Dugong Feeding Habits

Dugongs are unique marine mammals that inhabit the warm coastal waters of the Indo-Pacific region.

These large, gentle creatures spend their days grazing on seagrass meadows, making them an important part of the marine ecosystem.

The dugong’s diet is made up of a variety of aquatic plants and algae, which they feed on throughout the day in shallow depths.

Feeding behavior largely depends on the size and age of an individual dugong. Young animals tend to feed more frequently than adults since they need more energy for growth and development.

This can include up to eight hours per day spent grazing on seagrass beds or walking along with their snouts close to the ocean floor in search of food.

Habitat of a Dugong

The dugong is a large, gentle marine mammal native to the warm coastal waters of the Indian and Pacific Oceans. This unique species is found in shallow waters around coral reefs, seagrass meadows, estuaries, and deltas.

The dugong prefers habitats with a wide variety of seagrasses that can provide it with food as well as shelter from predators.

Dugongs are also known to inhabit brackish lagoons and mangrove swamps where they eat algae and sea grasses.

Dugongs travel great distances in search of new areas to feed on and often follow ocean currents for long periods of time before settling into new habitats.

Dugong Reproductive Behavior

Dugongs are fascinating creatures that have unique and complex reproductive behavior. The courtship of dugongs is quite elaborate.

Male dugongs will perform courtship display behaviors that involve vocalizations, head bobbing, and tail slapping against the surface of the water.

They have even been observed blowing bubbles around a female to attract her attention. Females may respond by raising their heads out of the water or performing a special swimming motion with their fluke to indicate interest in the male’s advances.

Dugongs mate throughout the year and the female mate multiple times with different males to increase her chance of impregnation.

Once mating has occurred, pregnant females will migrate to protected areas such as lagoons and estuaries for calving grounds where they can give birth safely from predators.

Dugong Social Behavior

Although they are typically solitary creatures, dugongs will come together during mating seasons to reproduce.

These large marine mammals have a complex social behavior that has been studied extensively by researchers.

Dugongs communicate with each other through vocalization, body posturing, and other forms of communication.

The dugong’s social behavior is essential to its survival in its natural environment, helping it find food sources, mate successfully and protect itself from potential threats.

3. Dugong Behavioral Adaptations

Dugongs are large marine mammals that inhabit the shallow coastal waters of tropical and subtropical oceans.

They have adapted to their environment through a variety of behavioral adaptations. These adaptations enable them to feed and avoid predators.

One significant adaptation is the way they feed on seagrass in shallow waters. Dugongs can use their strong pair of incisor-like tasks to tear at the grass and then suck up the vegetation with their lips, allowing them to eat large amounts of food quickly.

This adaptation helps them forage more efficiently in low-visibility waters where predators may be present.

Additionally, dugongs can adapt their feeding habits depending on the seasonal availability of seagrass and other plants found within estuaries or mangroves.

Finally, another adaptation is the ability of dugongs to use their powerful tails as a defense mechanism against potential threats in the water. They use this tail-swiping behavior as a warning sign when they sense danger.

4. Dugong Manatee Difference

Dugongs and manatees are both aquatic mammals, but they have distinct differences. For one, the dugong is found in the Indian and Pacific oceans while the manatee resides in warmer coastal waters of the Atlantic Ocean.

They also vary in size, dugongs can grow up to 9 feet (3 meters) long and weigh up to 400 kilograms, while the larger West Indian Manatees can reach lengths of 13 feet and weigh 1300 pounds.

Additionally, their physical appearance differs. Dugongs are characterized by an elongated tail fluke that tapers to a point and wide flippers with nails at their tips, while manatees have shorter tails with rounded tips and wide flat flippers without nails.

5. Dugong Conservation Status

The conservation status of the dugong is precarious. Dugongs are considered vulnerable to extinction by the International Union for Conservation of Nature (IUCN).

This is due to their slow reproductive rates and significant threats from human activities such as hunting and habitat destruction.

Dugongs feed on seagrass beds along coastal areas that have been degraded by climate change and water pollution caused by urban development. As a result, their natural food supply has decreased significantly over recent years.

6. Frequently Asked Questions (FAQs)

Are Dugongs Friendly?

Dugongs have a reputation for being shy creatures and usually avoid contact with humans. However, when given the chance to do so, they have been known to interact with divers in a positive way.

They are also quite nurturing towards their calves and can often be seen swimming alongside them protectively.

Overall, dugongs tend to keep to themselves but given the right circumstances, they can show signs of friendliness towards humans.

Is a Dugong Dangerous?

While these animals may look intimidating with their large size and sharp tusks, they’re quite gentle creatures. Dugongs are herbivores who feed on sea grasses found in shallow coastal waters.

They’re known to be slow-moving and docile animals who tend to shy away from humans. In fact, it’s very rare for dugongs to attack or harm people in any way.

So, while they may appear to be dangerous, they won’t hurt you if you come across one in the wild.

However, it’s still important to exercise caution when interacting with a dugong or its habitat, they can become stressed or frightened if approached too closely or rapidly by people or boats.

How Long Do Dugongs Live?

Dugongs are one of the most fascinating creatures in the ocean, and they have a very interesting lifespan.

Dugongs can live anywhere from 50 to 70 years or even longer, depending on their environment. They are one of the longest-living mammals on earth.

The dugong is an herbivorous marine mammal that spends its days grazing for seagrasses in shallow coastal waters.

Dugong Behavior-AnimalBehaviorCorner

It has been found that the number of years a dugong will live depends largely upon where it lives, as well as its access to food sources such as seagrass meadows.

Seagrasses provide crucial shelter, nutrition, and protection for these animals against predators like sharks and killer whales.

Therefore, dugongs that have access to extensive seagrass beds may often outlive those located in less optimal habitats with limited resources.


In conclusion, the dugong is an unusual, yet fascinating creature. Its behavior is complex and diverse and requires further study to better understand how this species interacts with its environment.

Though the dugong’s population is decreasing due to human interference, it continues to be a captivating animal that has much to teach us about animals in the wild.

We should strive to preserve the habitats of these animals so that future generations can appreciate their beauty and learn from their behavior.
