Pseudoboletia maculata is a species of sea urchin. [1] [2] It is found in the western central Pacific Ocean. It is known in Indonesia, the tropical eastern Indian Ocean, and on the Great Barrier Reef. This species is reef-associated, and lives at depths of between 10 and 82 metres. [2]
The Caribbean Sea is a sea of the Atlantic Ocean in the tropics of the Western Hemisphere. It is bounded by Mexico and Central America to the west and southwest, to the north by the Greater Antilles starting with Cuba, to the east by the Lesser Antilles, and to the south by the northern coast of South America. The Gulf of Mexico lies to the northwest. The entire Caribbean Sea area, the numerous islands of the West Indies, and adjacent mainland coastal regions are collectively known as the Caribbean.
Marine biology is the scientific study of the biology of marine life, organisms that inhabit the sea. Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy.
A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups.
Triggerfish are about 40 species of often brightly colored fish of the family Balistidae. Often marked by lines and spots, they inhabit tropical and subtropical oceans throughout the world, with the greatest species richness in the Indo-Pacific. Most are found in relatively shallow, coastal habitats, especially at coral reefs, but a few, such as the oceanic triggerfish, are pelagic. While several species from this family are popular in the marine aquarium trade, they are often notoriously ill-tempered.
Coral bleaching is the process when corals become white due to loss of symbiotic algae and photosynthetic pigments. This loss of pigment can be caused by various stressors, such as changes in temperature, light, or nutrients. Bleaching occurs when coral polyps expel the zooxanthellae that live inside their tissue, causing the coral to turn white. The zooxanthellae are photosynthetic, and as the water temperature rises, they begin to produce reactive oxygen species. This is toxic to the coral, so the coral expels the zooxanthellae. Since the zooxanthellae produce the majority of coral colouration, the coral tissue becomes transparent, revealing the coral skeleton made of calcium carbonate. Most bleached corals appear bright white, but some are blue, yellow, or pink due to pigment proteins in the coral.
The Florida Keys National Marine Sanctuary is a U.S. National Marine Sanctuary in the Florida Keys. It includes the Florida Reef, the only barrier coral reef in North America and the third-largest coral barrier reef in the world. It also has extensive mangrove forest and seagrass fields. The Florida Keys National Marine Sanctuary, designated in 1990, is the ninth national marine sanctuary to be established in a system that comprises 13 sanctuaries and two marine national monuments. The Florida Keys National Marine Sanctuary protects approximately 2,900 square nautical miles of coastal and ocean waters from the estuarine waters of south Florida along the Florida Keys archipelago and the Hawk Channel passage, encompassing more than 1,700 islands, out to the Dry Tortugas National Park, reaching into the Atlantic Ocean, Florida Bay and the Gulf of Mexico.
Marine conservation, also known as ocean conservation, is the protection and preservation of ecosystems in oceans and seas through planned management in order to prevent the over-exploitation of these marine resources. Marine conservation is informed by the study of marine plants and animal resources and ecosystem functions and is driven by response to the manifested negative effects seen in the environment such as species loss, habitat degradation and changes in ecosystem functions and focuses on limiting human-caused damage to marine ecosystems, restoring damaged marine ecosystems, and preserving vulnerable species and ecosystems of the marine life. Marine conservation is a relatively new discipline which has developed as a response to biological issues such as extinction and marine habitats change.
Mene rhombea is an extinct perciform fish belonging to the family Menidae. During the Middle Eocene, about 48 to 40 mya, these fishes lived in the Tethys Ocean, a large tropical sea in the area corresponding to the current Mediterranean. This ocean was extended between the continents of Gondwana and Laurasia. At this time, where Monte Bolca is today, M. rhombea, and its relative, M. oblonga, lived in a tropical lagoon.
The spotted houndshark is a houndshark of the family Triakidae found in tropical waters in the eastern Pacific Ocean off the coast of South America. It usually grows to a length around 180 centimetres (71 in). The reproduction of this houndshark is ovoviviparous, with a litter of 14 pups being found in one female with a birth size of 30 to 40 centimetres. Their diet is believed to consist mainly of crustaceans.
The Belize Barrier Reef is a series of coral reefs straddling the coast of Belize, roughly 300 metres (980 ft) offshore in the north and 40 kilometres (25 mi) in the south within the country limits. The Belize Barrier Reef is a 300-kilometre (190 mi) long section of the 900-kilometre (560 mi) Mesoamerican Barrier Reef System, which is continuous from Cancún on the north-eastern tip of the Yucatán Peninsula through the Riviera Maya and down to Honduras, making it the second largest coral reef system in the world after the Great Barrier Reef in Australia. It is Belize's top tourist destination, popular for scuba diving and snorkeling and attracting almost half of its 260,000 visitors. It is also vital to the country's fishing industry.
Triopha maculata, common name spotted triopha or speckled triopha, is a species of colorful sea slug, a nudibranch, a shell-less marine gastropod mollusk in the family Polyceridae. This species is very variable in color.
The Coral Triangle (CT) is a roughly triangular area in the tropical waters around the Philippines, Indonesia, Malaysia, Papua New Guinea, the Solomon Islands and Timor-Leste. This area contains at least 500 species of reef-building corals in each ecoregion. The Coral Triangle is located between the Pacific and Indian oceans and encompasses portions of two biogeographic regions: the Indonesian-Philippines Region, and the Far Southwestern Pacific Region. As one of eight major coral reef zones in the world, the Coral Triangle is recognized as a global centre of marine biodiversity and a global priority for conservation. Its biological resources make it a global hotspot of marine biodiversity. Known as the "Amazon of the seas", it covers 5.7 million square kilometres (2,200,000 sq mi) of ocean waters. It contains more than 76% of the world's shallow-water reef-building coral species, 37% of its reef fish species, 50% of its razor clam species, six out of seven of the world's sea turtle species, and the world's largest mangrove forest. In 2014, the Asian Development Bank (ADB) reported that the gross domestic product of the marine ecosystem in the Coral Triangle is roughly $1.2 trillion per year and provides food to over 120 million people. According to the Coral Triangle Knowledge Network, the region annually brings in about $3 billion in foreign exchange income from fisheries exports, and another $3 billion from coastal tourism revenues.
The hawksbill sea turtle is a critically endangered sea turtle belonging to the family Cheloniidae. It is the only extant species in the genus Eretmochelys. The species has a global distribution that is largely limited to tropical and subtropical marine and estuary ecosystems.
The Maldives, officially the Republic of Maldives, is a small archipelagic state in South Asia. It lies in the Indian Ocean southwest of Sri Lanka and India, about 700 kilometres (430 mi) from the Asian continent's mainland. The chain of 26 atolls stretches across the Equator from Ihavandhippolhu Atoll in the north to Addu Atoll in the south. The land area is roughly 298 square kilometres. Malé is the capital.
Human activities have substantial impact on coral reefs, contributing to their worldwide decline. Damaging activities encompass coral mining, pollution, overfishing, blast fishing, as well as the excavation of canals and access points to islands and bays. Additional threats comprise disease, destructive fishing practices, and the warming of oceans.[2] Furthermore, the ocean's function as a carbon dioxide sink, alterations in the atmosphere, ultraviolet light, ocean acidification, viral infections, the repercussions of dust storms transporting agents to distant reefs, pollutants, and algal blooms represent some of the factors exerting influence on coral reefs. Importantly, the jeopardy faced by coral reefs extends far beyond coastal regions. The ramifications of climate change, notably global warming, induce an elevation in ocean temperatures that triggers coral bleaching—a potentially lethal phenomenon for coral ecosystems.
Granata maculata is a species of small sea snail, a marine gastropod mollusc in the family Chilodontaidae.
Mene maculata, the moonfish, is the only extant member of the genus Mene and of the family Menidae. The body is highly compressed laterally and very deep vertically. The ventral profile is steep, with a sharp ventral edge. The caudal (tail) fin is deeply forked. The mouth is small and protrusible. The body is silvery below and blue-green on the back, with three to four rows of dark gray spots on the upper side. The first two rays of the pelvic fin are greatly elongated, forming a prominent backward-pointing process on the underside of the fish.
Synapta maculata, the snake sea cucumber, is a species of sea cucumber in the family Synaptidae. It is found in shallow waters in the tropical Indo-Pacific Ocean. Sometimes growing as long as 3 m (10 ft), it is one of the longest sea cucumbers in the world.
Amed is a village on the east coast in Abang District, Karangasem Regency, Bali, Indonesia. In the wake of heavy tourism development, actors in the tourism industry use the village's name to designate a 14-km stretch of coast that includes several other villages, namely from west to east: Amed, Jemeluk, Bunutan, Lipah, Lehan, Selang, Banyuning, Aas and Kusambi. A more correct geographical name would be the north coast of the Seraya peninsula, or North Seraya.
