Best places to dive with Giant moray

Moray eels, including large individuals, live in the wreck recesses and holds. Seen year-round on most sites.

Moray eels are common in the boulders and wreck recesses across Hin Luk Bat, Hin Raab and the HTMS Chang.

Moray Beach takes its name from them and they are seen on most dives there, tucked into coral heads and rubble. Present year-round.

Resident in reef crevices across Tiran and Ras Mohammed year-round, holed up by day and free-swimming to hunt at night.

Resident in the coral heads and ledges across the Ribbon Reefs; commonly seen at Challenger Bay and Two Towers, more active at night. Year-round.

Resident in the holds, portholes and wreckage of most ships.

Morays hole up in the wreck structure and are seen on most of the hulls, but sightings are incidental rather than a reason to book. Coded occasional because no source treats them as reliable.

Morays are a standard part of the Con Dao reef fauna, holed up in the hard coral structure. Species identification in operator reports is loose, so not every large moray seen is Gymnothorax javanicus.

Possible in suitable habitat; no unsupported monthly peak is applied.

Moray eels are routine on the rocky inshore reefs, and Koh Prins has a site named Moray Eel Parade for the number of species on one sand-and-rock stretch. Species-level identification is not documented.

In the cracks at Tokong Laut and in the boulder gullies at Terumbu Tiga and Tunnel Point. Smaller honeycomb and yellow-edged morays are more numerous; a genuinely large giant moray is a once-a-trip sighting.

Moray eels are reported from the reef system, but species-level local records and sighting frequency are thin; this is coded conservatively.

Moray eels are reported on Subic wrecks, but sources rarely identify them to species; giant moray is therefore coded rare and provisional.
