Vanuatu marine life and responsible dugong encounters
Moso diving rewards attention to coral and small reef life as much as a watch for turtles, rays or schooling fish. Every animal is free-ranging. Havannah Harbour is documented dugong habitat, but a visitor’s chance of seeing a dugong cannot be predicted from that fact.
What wildlife could I see?
Reef fish, anemonefish, groupers, nudibranchs and other small creatures give divers something to look for on most sites. Turtles, trevally, barracuda, eagle rays and reef sharks are possibilities in suitable habitat and conditions. A photograph on a trip page shows a possible encounter, not a species included in the package.
Are turtles likely?
Abyss describes green and hawksbill turtles among the local possibilities, especially over multiple dives. They remain wild, and sightings vary with site, season, conditions and luck. The trip is designed around a range of reefs and terrain so it is enjoyable even on a day without a turtle.
Will I see a dugong?
A dugong may pass through the wider Moso and Havannah seagrass system, but no Abyss departure includes a dedicated dugong search, swim or guaranteed sighting. The site research supports presence, not an encounter probability, season or fixed route. Choose the trip for the diving and regard a dugong as a fortunate extra.
Can I swim toward a dugong if one appears?
No. Remain calm, keep its path clear, avoid approaching or following it, and take the local guide’s direction. Never touch, feed, chase or crowd a dugong, especially a mother and calf. Any in-water observation must be suitable and lawful; a chance sighting on a normal dive does not become a planned swim.
What about sharks, rays and larger fish?
An outer reef or current-fed site may bring reef sharks, eagle rays, devil rays or schooling fish, but none is a guaranteed attraction. The skipper and guide will select a site for safety and suitability rather than chase a particular species. Ask about what has been seen recently while understanding that yesterday’s sightings do not predict tomorrow’s.
Can I touch coral or take souvenirs?
Leave living and historical material in place. Good buoyancy and a controlled fin position help prevent coral damage; the guide can help choose a route that is comfortable for you. Avoid touching wildlife, feeding fish or collecting items from reefs and wrecks, and follow local conservation instructions.
