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.
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.
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.
The Aquarium of the Pacific is a public aquarium on a 5-acre (20,000 m2) site on Rainbow Harbor in Long Beach, California, United States. It is situated across the water from the Long Beach Convention Center, Shoreline Village, and the Queen Mary Hotel and Attraction.
Kayangel (Ngcheangel) is the northernmost state of Palau 24 km (15 mi) north of Koror. The land area is about 1.4 km2 (0.54 sq mi). The population is 54.
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 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.
Kakaban island is part of the Derawan Islands, East Kalimantan, Indonesia.
Exyrias akihito is a species of marine goby. Since the recent description of this species it has been found to have a wide distribution in the western Pacific including the Great Barrier Reef, New Guinea, Indonesia, the Philippines and the Yaeyama Islands, Japan. One individual was photographed in Palau, and on January 13, 2005 one was caught in the lagoon of Majuro Atoll in the Marshall Islands. This animal had only 9 soft rays in its dorsal fin instead of the normal 10, a congenital abnormality known to occasionally occur in gobies and other fish.
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.
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.
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.
Uet era Ongael 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.
Ulong is a major island and channel of western Palau. It is sometimes called Aulong and originally written Oroolong in English. Ulong is regarded by many as one of the best drift dives in the world.
Ongael Island is an island in Koror State, Palau. It is the location of the famous Ongael Lake.
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.
An anchialine system is a landlocked body of water with a subterranean connection to the ocean. Depending on its formation, these systems can exist in one of two primary forms: pools or caves. The primary differentiating characteristics between pools and caves is the availability of light; cave systems are generally aphotic while pools are euphotic. The difference in light availability has a large influence on the biology of a given system. Anchialine systems are a feature of coastal aquifers which are density stratified, with water near the surface being fresh or brackish, and saline water intruding from the coast at depth. Depending on the site, it is sometimes possible to access the deeper saline water directly in the anchialine pool, or sometimes it may be accessible by cave diving.
