Aprostatum clippertoni is a species of flatworm belonging to the family Euplanidae. [1] It is found in the Northern Pacific Ocean.
A. clippertoni has been observed to reach up to 17 mm in length, and about 7 mm wide. Its eyes are loosely arranged and cerebral. The penis papilla is small with a pocket, a sheath, and a short stylet. The vagina is long and muscular with an S-bend. A small Lang's vesicle is present, and the genital pores are separated. [2]
Though not explicitly stated in the original description, the specific epithet of clippertoni is almost certainly derived from Clipperton Island, where the type specimen was found. [2]
A. clippertoni is known to be found in the Pacific Ocean around Clipperton Island. [2]
Clipperton Island, also known as Clipperton Atoll and previously referred to as Clipperton's Rock, is an 8.9 km2 (3.4 sq mi) uninhabited French coral atoll in the eastern Pacific Ocean. The only French territory in the North Pacific, Clipperton is 10,675 km (6,633 mi) from Paris, France; 5,400 km (2,900 nmi) from Papeete, French Polynesia; and 1,280 km (690 nmi) from Acapulco, Mexico.
The Oceanian realm is one of the World Wildlife Fund (WWF) biogeographic realms, and is unique in not including any continental land mass. It has the smallest land area of any of the WWF realms.
Polymetallic nodules, also called manganese nodules, are mineral concretions on the sea bottom formed of concentric layers of iron and manganese hydroxides around a core. As nodules can be found in vast quantities, and contain valuable metals, deposits have been identified as a potential economic interest. Depending on their composition and autorial choice, they may also be called ferromanganese or polymetallic nodules. Ferromanganese nodules are mineral concretions composed of silicates and insoluble iron and manganese oxides that form on the ocean seafloor and terrestrial soils. The formation mechanism involves a series of redox oscillations driven by both abiotic and biotic processes. As a byproduct of pedogenesis, the specific composition of a ferromanganese nodule depends on the composition of the surrounding soil. The formation mechanisms and composition of the nodules allow for couplings with biogeochemical cycles beyond iron and manganese. The high relative abundance of nickel, copper, manganese, and other rare metals in nodules has increased interest in their use as a mining resource.
Socorro Island is a volcanic island in the Revillagigedo Islands, a Mexican possession lying 600 kilometres (370 mi) off the country's western coast. The size is 16.5 by 11.5 km, with an area of 132 km2 (51 sq mi). It is the largest of the four islands of the Revillagigedo Archipelago. The last eruption was in 1993.

The masked booby, also called the masked gannet or the blue-faced booby, is a large seabird of the booby and gannet family, Sulidae. First described by the French naturalist René-Primevère Lesson in 1831, the masked booby is one of six species of booby in the genus Sula. It has a typical sulid body shape, with a long pointed yellowish bill, long neck, aerodynamic body, long slender wings and pointed tail. The adult is bright white with black wings, a black tail and a dark face mask; at 75–85 cm (30–33 in) long, it is the largest species of booby. The sexes have similar plumage. This species ranges across tropical oceans, except in the eastern Atlantic and eastern Pacific. In the latter, it is replaced by the Nazca booby, which was formerly regarded as a subspecies of masked booby.
The Galapagos shark is a species of requiem shark, in the family Carcharhinidae, found worldwide. It favors clear reef environments around oceanic islands, where it is often the most abundant shark species. A large species that often reaches 3.0 m (9.8 ft), the Galapagos reef shark has a typical fusiform "reef shark" shape and is very difficult to distinguish from the dusky shark and the grey reef shark. An identifying character of this species is its tall first dorsal fin, which has a slightly rounded tip and originates over the rear tips of the pectoral fins.
The Tropical Eastern Pacific is one of the twelve marine realms that cover the coastal waters and continental shelves of the world's oceans. The Tropical Eastern Pacific extends along the Pacific Coast of the Americas, from the southern tip of the Baja California Peninsula in the north to northern Peru in the south. It is bounded on the north by the Temperate Northern Pacific realm, and on the south by the Temperate South America realm.
Determining the boundaries between the continents is generally a matter of geographical convention. Several slightly different conventions are in use. The number of continents is most commonly considered seven but may range as low as four when Afro-Eurasia and the Americas are both considered as single continents. An island can be considered to be associated with a given continent by either lying on the continent's adjacent continental shelf or being a part of a microcontinent on the same principal tectonic plate. An island can also be entirely oceanic while still being associated with a continent by geology or by common geopolitical convention. Another example is the grouping into Oceania of the Pacific Islands with Australia and Zealandia.
Johngarthia is a genus of crabs in the land crab family Gecarcinidae, formerly included in the genus Gecarcinus, and containing six species. The genus bears the name of John S. Garth, a 20th century naturalist who specialized in crabs and other arthropods.
Kuhlia mugil, the barred flagtail, the fiveband flagtail or the five-bar flagtail, is a species of marine ray-finned fish, a flagtail belonging to the family Kuhliidae. It is found in the Indo-Pacific region.
The Clarion-Clipperton Zone (CCZ) or Clarion-Clipperton Fracture Zone is an environmental management area of the Pacific Ocean, administered by the International Seabed Authority (ISA). It includes the Clarion Fracture Zone and the Clipperton Fracture Zone, geological submarine fracture zones. Clarion and Clipperton are two of the five major lineations of the northern Pacific floor, and were discovered by the Scripps Institution of Oceanography in 1954. The CCZ is regularly considered for deep-sea mining due to the abundant presence of manganese nodules.
Paranthias colonus is a species of grouper found in the Eastern Pacific Ocean. They are typically found in small aggregations well above reefs, but will retreat to the reef at the approach of danger. They form large midwater schools while feeding on plankton. They occur up the a depth of 100 m. They feed mainly on small planktonic animals that are picked individually from the water, made possible by their shortened snout which facilitates close-range binocular vision.
The burrito grunt is a species of marine ray-finned fish, a grunt belonging to the family Haemulidae. It is native to the tropical waters of the eastern Pacific Ocean area.
The Clarion angelfish is a species of marine ray-finned fish, a marine angelfish belonging to the family Pomacanthidae. It is found in the eastern Pacific Ocean, almost exclusively near islands off the Pacific coast of Mexico.
Johngarthia planata is a bright orange species of land crab that lives on inshore islands and the continental mainland coast of the tropical and subtropical Pacific coast of the Americas, including the Gulf of California, Costa Rica, Colombia, and continental mainland beaches of Mexico. The crabs are omnivorous and feed on seaweed (algae), vegetation and sometimes carrion.
The Central American Pacific Islands is a biogeographical area used in the World Geographical Scheme for Recording Plant Distributions. It has the Level 3 code "CPI". It consists of a number of islands off the western coast of Central America in the Pacific Ocean: Clipperton Island, Cocos Island and Malpelo Island.
Emoia cyanura, the copper-tailed skink, is a species of skink. It is found in Borneo, Clipperton Island and other South Pacific islands.
The Clipperton angelfish is a species of marine ray-finned fish, a marine angelfish belonging to the family Pomacanthidae. It is endemic to Clipperton Island, a French possession in the eastern Pacific Ocean.
Johngarthia oceanica, also known as Clipperton crab, is a bright orange species of land crab that lives on Clipperton Island and on Socorro Island in the Revillagigedo Islands off Mexico in the tropical eastern Pacific. Prior to 2019, J. oceanica was considered part of J. planata, however a reexamination determined the land crabs on the oceanic islands to be a separate species. J. oceanica differs from J. planata in the shape of the mesial lobe of the infraorbital margin and the color of its carapace.
