Palau Aquarium
An aquarium in Koror run by a marine research centre, showing local habitats.
Updated 3 September 2026
The aquarium in Koror is run by the Palau International Coral Reef Center, a research institution, and its tanks follow Palau's habitats in sequence from mangrove and seagrass through the lagoon to the outer reef and the deep, with the species that live in each. Giant clams, chambered nautilus and reef fish are among the displays. The research side of the centre works on coral and on giant clam culture. The centre was built with Japanese assistance and opened in 2001, and its research work covers reef monitoring across the region.
