Although Palau is small in size, it offers surprising diversity of interesting monuments. Several of these monuments are true wonders and there are several unresolved mysteries related to Palau.
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.

Featured: Jellyfish Lake
The most outstanding natural monument in Palau is Jellyfish Lake - small, meromictic (layered) lake with seawater.
