Question: Procaris ascensionis is a species of shrimp, known only from two saltwater pools on which isolated volcanic island, in the equatorial waters of the South Atlantic Ocean?
Context: Procaris hawaiana is a species of shrimp in the family Procarididae, from Maui, Hawaii.  The species is very similar to "Procaris ascensionis" from Ascension Island.  In "P. ascensionis" the integument is less firm, the rostrum is shorter, the cervical groove is more distinct, and the third abdominal somite reaches less far posteriorly over the fourth; also the scaphocerite has the final tooth still less distinct than in "P. hawaiana", and the last segment of its antennal peduncle is less slender. The black jack, "Caranx lugubris" (also known as the black trevally, black kingfish, coal fish and black ulua), is a species of large ocean fish in the jack family Carangidae.  The species has a circumtropical distribution, found in oceanic, offshore waters of the tropical zones of the Pacific, Atlantic and Indian Oceans.  The species is particularly prevalent around offshore islands such as the Caribbean islands in the Atlantic, Hawaii and French Polynesia in the Pacific and the Seychelles and Maldives in the Indian Ocean.  Black jack are rare in shallow waters, preferring deep reefs, ledges and seamounts in clear waters.  The species is easily distinguished by its black to grey fins and jet black scutes, with the head having a steep profile near the snout.  The largest recorded length is 1 m and weight of 17.9 kg.  The black jack lives either individually or in small schools, and is known to school with other species.  It is a predatory fish, taking a variety of fish, crustaceans and molluscs as prey.  Sexual maturity is reached at 34.6 cm in females and 38.2 cm in males, with spawning taking place between February and September in the Caribbean.  The early life history of the species is very poorly understood.  Black jack are of high importance to many island fisheries, but are rarely encountered in most continental fisheries.  The species has a reputation as a gamefish, and is variably considered a terrible or excellent food fish, although several cases of ciguatera poisoning have been attributed to the species.  The species was initially named "Caranx ascensionis" by Georges Cuvier, however several issues with the use of this name have seen Felipe Poey's name "Caranx lugubris" become the valid scientific name. Gunungapi Wetar is an isolated volcanic island to the north of Wetar island in the Banda Sea, Indonesia.  The island, a stratovolcano, only extends 282 m above sea level, but the total height of the summit from the sea bed is over 5000 m. Explosions in 1512 and 1699 are the only historical eruptions of the volcano. Procaris ascensionis is a species of shrimp, known only from two saltwater pools on Ascension Island; the larger of the two pools is about 4.5 m in diameter and contains 45 cm of water. Anogramma ascensionis, the Ascension Island parsley fern, is a species of fern in the Pteridaceae family that is endemic to Ascension Island, a volcanic island in the South Atlantic Ocean.  It is one of eight putative species in the "Anogramma" genus.  It was thought to have become extinct due to habitat loss, until four plants were found on the island in 2010.  Over 60 specimens were then successfully cultivated at Royal Botanic Gardens, Kew and on Ascension Island.  It is now classified as Critically Endangered. The South Sandwich Trench is a deep arcuate trench in the South Atlantic Ocean lying 100 km to the east of the South Sandwich Islands.  The trench is produced by the subduction of the southernmost portion of the South American Plate beneath the small South Sandwich Plate.  The South Sandwich Islands constitute a volcanic island arc which results from this active subduction.  Mount Belinda on Montagu Island is an active volcano. Gough Island , also known historically as Gonçalo Álvares (after the Portuguese explorer) or mistakenly as Diego Alvarez, is a volcanic island in the South Atlantic Ocean.  It is a dependency of Tristan da Cunha and part of the British overseas territory of Saint Helena, Ascension and Tristan da Cunha.  It is uninhabited except for the personnel of a weather station (usually six people) which the South African National Antarctic Programme has maintained continually on the island since 1956.  It is one of the most remote places with a constant human presence. Parting of the Waters is an unusual hydrologic site at Two Ocean Pass on the Great Divide, within the Teton Wilderness area of Wyoming's Bridger-Teton National Forest.  Two Ocean Pass separates the headwaters of Pacific Creek, which flows west to the Pacific Ocean, and Atlantic Creek, which flows east to the Atlantic Ocean.  At Parting of the Waters, at , North Two Ocean Creek flows down from its drainage on the side of Two Ocean Plateau and divides its waters more-or-less equally between its two distributaries, Pacific Creek and Atlantic Creek.  From this split, Two Ocean Creek waters flow either 3488 mi to the Atlantic Ocean via Atlantic Creek and the Yellowstone, Missouri and Mississippi Rivers, or 1353 mi to the Pacific Ocean via Pacific Creek and the Snake and Columbia Rivers.  In the marshy area of Two Ocean Pass adjacent to Parting of the Waters, water actually covers the Continental Divide such that a fish could swim from the Pacific Ocean to the Atlantic Ocean drainages.  In fact, it is thought that this was the pass that provided the route for Yellowstone cutthroat trout to migrate from the Snake River (Pacific) to Yellowstone River (Atlantic) drainages. Komba Island is a small isolated volcanic island located in Flores Sea, Indonesia.  The island is administratively part of Lembata Regency, East Nusa Tenggara.  it is located approximately 70 km northeast of Lembata Island.  The island contains Mount Batutara, a volcano which erupts in every 20 minutes. Ascension Island is an isolated volcanic island in the equatorial waters of the South Atlantic Ocean, around 1600 km from the coast of Africa and 2250 km from the coast of Brazil, which is roughly midway between the horn of South America and Africa.  It lies 7°56' South of the Equator.  It is governed as part of the British Overseas Territory of Saint Helena, Ascension and Tristan da Cunha, of which the main island, Saint Helena, is around 1300 km to the southeast.  The territory also includes the sparsely populated Tristan da Cunha archipelago, some 3730 km to the south, about halfway to the Antarctic Circle.
