Giant Clam
Tridacna gigas
Sighting evidence at Mwahnd Passage, Pohnpei
The coral gardens inside Mwahnd Passage contain one of Pohnpei's healthiest populations of giant clams, with multiple large individuals exceeding 80 centimetres in shell length settled among the coral heads at 5 to 12 meters. These filter-feeding bivalves live for over a century and their presence in large numbers indicates a site that has been free from collection pressure for several generations. The vivid blue, green, and purple mantle colours of these animals make them among the most visually striking subjects for wide-angle photography on the passage dives.
