Uet era Ongael (Ongael Lake) is a marine lake located on Ongael Island, Koror, in Palau. There are about 70 other marine lakes located throughout the Rock Islands and Koror. Uet era Ongael is notable for endemic subspecies of golden jellyfish and is one of five marine lakes in Palau used for several scientific researches in evolutionary biology, the other lakes being Jellyfish Lake, Clear Lake, Uet era Ngermeuangel and Goby Lake.
Uet era Ongael is connected to the ocean through fissures and tunnels in the limestone of ancient Miocene reefs. However the lake is sufficiently isolated and the conditions are different enough that the diversity of species in the lake is greatly reduced from the nearby lagoon. The golden jellyfish Mastigias cf. papua remengesaui [1] is substantially different from their close relatives living in the nearby lagoons. This is the most ornate of Palau lake jellyfishes, with solid white spots; younger jellyfish have a pale blue color. The small lake is also home to jellyfish of other species ( Aurelia sp., Cassiopea sp.).
Uet era Ongael is the smallest and shallowest Palau lake with registered endemic subspecies of jellyfish. The lake is holomictic - it does not have layers as it is comparatively shallow and with low banks, permitting for winds and sea tides to mix the water. [2]
The Republic of Palau consists of eight principal islands and more than 250 smaller ones lying roughly 500 miles southeast of the Philippines, in Oceania. The islands of Palau constitute the westernmost part of the Caroline Islands chain. The country includes the World War II battleground of Peleliu and world-famous rock islands. The total land area is 459 km2 (177 sq mi). It has the 42nd largest Exclusive Economic Zone of 603,978 km2 (233,197 sq mi).
Koror is the state comprising the main commercial centre of the Republic of Palau. It consists of several islands, the most prominent being Koror Island. It is Palau’s most populous state.
Airai, located on the southern coast of Babeldaob island, is the second-most populous state of Palau. It contains the country's chief airport, Roman Tmetuchl International Airport, and is connected by the Koror–Babeldaob Bridge to nearby Koror Island.
Peleliu is an island in the island nation of Palau. Peleliu, along with two small islands to its northeast, forms one of the sixteen states of Palau. The island is notable as the location of the Battle of Peleliu in World War II.
Angaur, or Ngeaur in Palauan, is an island and state in the island nation of Palau.
The Rock Islands of Palau, also called Chelbacheb, are a collection of several hundred small limestone or coral uprises in the Southern Lagoon of Palau between Koror and Peleliu, now an incorporated part of Koror State. There are between 250 and 300 islands in the group according to different sources, with an aggregate area of 42 square kilometers (16 sq mi) and a maximum height of 207 meters (679 ft). The islands were declared a UNESCO World Heritage Site in 2012.
Kayangel (Ngcheangel) is the northernmost state of Palau 86 km (53 mi) north of Koror. The land area is about 1.4 km2 (0.54 sq mi). The population is 54. There is one hamlet in the state - Orukei, which is also its capital. In 2020, Richard Ngiraked was elected governor of the state.
Tobi, or Hatohobei (Tobian), is the southernmost of Palau's sixteen states, consisting of Tobi Island and Helen Reef. The total land area is about 0.88 km². The population was 25 in 2015. Tobian, English, and Sonsorolese are the official languages of Hatohobei State.
Jellyfish Lake is a marine lake located on Eil Malk island in Palau. Eil Malk is a part of the Rock Islands, a group of small, rocky, mostly uninhabited islands in Palau's Southern Lagoon, between Koror and Peleliu. There are about 70 other marine lakes located throughout the Rock Islands. Millions of golden jellyfish migrate horizontally across the lake daily.

The spotted jelly, lagoon jelly, golden medusa, or Papuan jellyfish, is a species of jellyfish from the Indo-Pacific oceans. Like corals, sea anemones, and other sea jellies, it belongs to the phylum Cnidaria. Mastigias papua is one of the numerous marine animals living in symbiosis with zooxanthellae, a photosynthetic alga.
Mastigias is a genus of true jellyfish in the family Mastigiidae. It contains seven described species. Members of this genus are found widely in coastal regions of the Indo-Pacific, including saline lakes of Palau, but there are also records from the West Atlantic at Florida and Puerto Rico. The West Atlantic records are most likely the result of accidental introductions by humans.
Eil Malk or Mecherchar is the main island of the Mecherchar Islands, an island group of Palau in the Pacific Ocean. In a more narrow sense, just the southeastern peninsula of Mecherchar is called Eil Malk.
Clear Lake is a marine lake located on Eil Malk island in Palau. Eil Malk is part of the Rock Islands, a group of small, rocky, mostly uninhabited islands in Palau's Southern Lagoon, between Koror and Peleliu. There are about 70 other marine lakes located throughout the Rock Islands. Clear Lake is notable for endemic subspecies of golden jellyfish and is one of five marine lakes in Palau used for several scientific researches in evolutionary biology, the other lakes being Jellyfish Lake, Goby Lake, Uet era Ngermeuangel, Uet era Ongael.
Goby Lake is a marine lake located on Koror island in Palau. There are about 70 other marine lakes located throughout the Rock Islands and Koror. Goby Lake is notable for endemic subspecies of golden jellyfish and is one of five marine lakes in Palau used for several scientific researches in evolutionary biology the other lakes being Jellyfish Lake, Clear Lake (Palau), Uet era Ngermeuangel, Uet era Ongael.
Uet era Ngermeuangel is a marine lake located on Koror island in Palau. There are about 70 other marine lakes located throughout the Rock Islands and Koror. Uet era Ngermeuangel is notable for endemic subspecies of golden jellyfish and is one of five marine lakes in Palau used for several scientific researches in evolutionary biology the other lakes being Jellyfish Lake, Clear Lake (Palau), Goby Lake, Uet era Ongael.

The wildlife of Greece includes the diverse flora, fauna, and funga of Greece, a country in southern Europe. The country is mostly mountainous with a very long, convoluted coastline, consisting of peninsulas and many islands. The climate ranges from Mediterranean through temperate to alpine, and the habitats include mountains, hills, forests, rivers, lakes, coasts and cultivated land.
The Palau tropical moist forests is a tropical and subtropical moist broadleaf forests ecoregion in Micronesia. It encompasses the nation of Palau.
The golden jellyfish is a subspecies of spotted jellyfish that inhabits Jellyfish Lake on Eil Malk island in Palau in the western Pacific Ocean. Like the nominate subspecies, it derives part of its nutrition from symbiotic algae (Zooxanthellae) that live in their tissues and part of their nutrition from captured zooplankton.
