Air Prang is probably one of the most interesting sites at Lembeh Strait.
The name literally means 'War Water', referring to the jetty offering fresh water from an uphill aquifer, exploited by the Japanese during WW2.
This is an expansive shallow sand slope, more popular for night diving, especially when strong rising tides limit the possible options elsewhere in the middle section of the strait.
Good for Octopus species and recently popular for three Rhinopias found in the rubble sections on the Northern end of the site, but the barren terrain and low density of critters mean that it sees far fewer divers compared to the muck sites to its north. One highlight is the Bobbit Worm, commonly seen on night dives.
