Marine lakes

Highlight of the natural heritage of Palau is its unique marine lakes - lakes with marine water and weak connection to the sea. Since the geologically recent sea rise in these lakes there have developed unique biotopes.

  • Clear Lake - Rock Islands. Marine lake (3.9 ha) with its own subspecies of jellyfish Mastigias cf. papua salii.
  • Goby Lake - Rock Islands. Round marine lake (2.1 ha) with its own subspecies of jellyfish Mastigias cf. papua nakamurai.
  • Jellyfish Lake (Ongeim'l Tketau) - Eil Malk in Rock Islands. Unique marine lake with an area of 5.0 ha, has underground connection to the sea. Stratified in two layers which do not mix. Isolated from the sea 12,000 years and contains a distinct population of two species of jellyfish - endemic Mastigias cf. papua etpisoni and most likely endemic Aurelia sp. Millions of these jellyfishes make strict daily migration around the lake. Four more marine lakes with jellyfish in the nearby islands but Jellyfish Lake is the only one open to tourists. Number of jellyfish has reached up to 31 millions (January 2005), currently some 5 millions.
  • Uet era Ngermeuangel - Rock Islands. Marine lake (4.3 ha) with its own subspecies of jellyfish Mastigias cf. papua remeliiki and Moon Jellyfish Aurelia sp..
  • Uet era Ongael - Rock Islands. Small marine lake (0.9 ha) with its own subspecies of jellyfish Mastigias cf. papua remengesaui.

Caves under the sea level

When the sea level was below the limestone sediments of Palau karst processes formed numerous impressive caverns. Nowadays these caverns have been filled with sea water and are provide excellent diving experience.

  • Yikrel a Bub (Blue Holes, The Temple of Doom) - near Ngemelis, Koror. Unusual monument of nature created in times when sea level was considerably lower. Four deep holes in 1 - 2 metres deep seabed which unite in enormous underground hollow 40 meters below. Cave has two more openings to the side - through the submerged ancient sea cliff. Impressive blue light rays enter though the holes in the cave.
  • Siaes Tunnel - Koror. Impressive tunnel under the sea water, entrance 4 - 20 meters deep, bottom - up to 60 meters deep. Tunnel is lighted through 3 larger side openings and numerous smaller openings. Created by erosion processes in times when seawater level was lower than now.
  • Chandelier Cave (Iiel Temekai) - Koror. Limestone cave with dropstone formations, entrance and part of cave is located below sea level, below water. Four chambers.

The most outstanding natural monument in Palau is Jellyfish Lake - small, meromictic (layered) lake with seawater. Lake is approximately 420 meters long - but here live millions of jellyfish of endemic subspecies. Jellyfish constantly migrate in the small lake to be both in sunshine and avoid of predators - sea anemones.
