Dugong Sightings: The Sea Cow We Hope to Meet by Luck

Who is the dugong, really?

Can you plan to see a dugong? Honestly, no. You can go where they live, move slowly and hope. Dugongs are rare in many places, hard to find, and very sensitive to boats, so a sighting is luck, and a good trip never depends on it.

WWF calls dugongs “sea cows”. They graze on seagrass in the shallow coastal waters of the Indian and western Pacific Oceans.

They are cousins of the manatee and share the same round, gentle shape. But a dugong has a tail like a dolphin’s. And unlike manatees, which also use fresh water, the dugong lives only in the sea.

The international agreement for the species, the CMS Dugong Memorandum of Understanding, says dugongs live in 46 countries, from East Africa to Vanuatu in the Pacific. They can grow up to 3 metres long and weigh up to 500 kilograms. The oldest dugong ever recorded was 73 years old. You can meet the species on the dugong page of our Ocean Atlas.

A slow life that cannot recover quickly

Dugongs live long and breed very slowly. A female has her first calf somewhere between 6 and 18 years of age, after a pregnancy of 14 months. After that, she has a single calf only every 3 to 7 years.

There is one more condition. When there is not enough seagrass, a dugong does not breed normally.

So think about it this way. An animal that grows its family this slowly cannot quickly replace the ones it loses. Every single loss matters.

Are dugongs endangered? Some populations are in real trouble

Globally, the species is listed as Vulnerable. But some local populations are in a much worse place.

In 2022, the IUCN listed the East African dugong population as Critically Endangered, and the New Caledonian population as Endangered. Fewer than 250 mature dugongs remain in East Africa, and under 900 in New Caledonia. More than 90% of the East African dugongs live in one area, Mozambique’s Bazaruto seascape. Researchers have even described the Chinese dugong population as functionally extinct.

The main dangers come from us. In East Africa, dugongs are caught by accident in fishing gear. In New Caledonia, there is poaching. In both places, boats injure them. And their seagrass is damaged by pollution, coastal building, trawling and even boat anchors.

Why we never sell a dugong guarantee

A species living in a region does not mean a guest can find one on request. Dugongs can be hard to find, and in many places there are very few of them left.

Now picture a boat going up and down a seagrass meadow, searching. That is exactly the kind of disturbance these animals do not need, and boat injuries are already one of their main threats.

So we do not build trips around the promise of a dugong, and we are careful with any operator who does. Where dugongs live, any encounter must follow the local rules and the guidance of the local community. The rules differ from place to place, so we check them for each site instead of assuming.

Wildlife encounters are unpredictable. Snorkelling or boating in dugong habitat should always follow local regulations and experienced professional guidance.

A good day without a dugong

Here is something I love. A morning with no dugong can still be a very rich morning.

Learn to see seagrass as a living home, not an empty field between reefs. Ask your local guide about the conservation work in the area and how visitors can help. Keep boats slow and anchors off the seagrass, and leave shallow feeding areas in peace. For those long, bright hours on shallow water, I wear a long-sleeve rash guard and keep a mineral sunscreen in my bag.

If a dugong does appear

Do not chase it, touch it or feed it. Never block its path, and never come between a mother and her calf. Stay calm, stay still, and let it go on its way.

Local rules can be strict. In New South Wales, Australia, for example, a vessel may come no closer than 50 metres to a dugong. When a calf is present, vessels must stay out of a caution zone of 150 metres. These numbers belong to that place, but the spirit works everywhere: give the animal space, and let it choose.

Good operators keep their speed low in shallow water, avoid driving over seagrass, brief guests before any trip in dugong habitat, and are happy to come back without a sighting. If this slow way of meeting the ocean feels right to you, our Ocean Match can help you find a local team and a trip that fits.

Questions people ask

Wildlife encounters are never guaranteed and never forced. Ocean Calling works only with vetted, ethical local operators, and every animal is free to approach, or not, entirely on its own terms.
