Rhyacichthyidae
The Rhyacichthyidae or loach gobies are a small family of perciform fish in two genera. The three species all inhabit rivers and streams, often with fast flow. ''R. aspro'' is widespread in Western Pacific region (China and Japan to New Guinea and the Solomons), but the two remaining species are restricted to New Caledonia and Vanuatu. Little is known about their breeding behavior, but the eggs or larvae float down into the sea where the young grow up, only to later return to the adult river and stream habitat. They are fairly small fish, no more than in standard length.

Rhyacichthys Aspro
The loach goby, ''Rhyacichthys aspro'', is a goby belonging to the family Rhyacichthyidae. It is not fished commercially. Taxonomy The loach goby is one of the two species classified under the genus ''Rhyacichthys'' in the family Rhyacichthyidae. Thacker and Hardman's study of the molecular phylogeny of gobies indicates the loach goby is the most primitive member of the Gobioidei. Description The loach goby is long. It has eight dorsal spines, eight or 9 soft dorsal rays, one anal spine, and eight or 9 anal rays. The head is flattened vertically, with a snout and small eyes. The mouth is on the underside and has a fleshy upper lip. The body is laterally compressed toward the slightly forked tail; it has a well-developed lateral line system. The pelvic fins are separate, with enlarged musculature. In colour, it is light brown, with darker, longitudinal stripes on its flanks. Also, dark stripes occur on the dorsal, caudal, and pectoral fins. Distribution and habitat The loach g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhyacichthys Guilberti
''Rhyacichthys guilberti'' is a goby belonging to the family Rhyacichthyidae. This fish only occurs in the Northern Province of New Caledonia and in Vanuatu. It is found in only two rivers. Its maximum standard length of about 240 mm. Its population on New Caledonia was estimated at less than 400 individuals, but it is now thought to have been extirpated from that island, it remains common on Vanuatu. ''Rhyacichthys guilberti'' occurs in coastal streams with a relatively steep gradient set in hilly or mountainous terrain. It feeds on algae and diatoms on rocks and stones. holding on in the fast current using its broadened pelvic and pectoral fins and its compressed head and snout. The specific name honours the French entomologist Eric Guilbert who was involved in collecting the type specimen In biology, a type is a particular wikt:en:specimen, specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally as ...

Protogobius
Protogobius attiti is a species of loach goby which is endemic to nine rivers in South Province, New Caledonia. It occurs in rivers with ultramafic beds. It prefers areas where there is a gravel substrate under overhanging vegetation in slower reaches of fast flowing, clear streams. The rocks and gravel in the areas in which it occurs are usually coated with detritus. When threatened it buries itself in the gravel leaving its eyes, mouth and first dorsal fin above the substrate. Its main prey is small freshwater crustaceans, especially the abundant transparent shrimp which occur in these streams. It is threatened by nickel mining which creates sediments which blanker the rocks on which it hides and destroys the algae its prey feed on. The specific name honours a Melanesian chief of Goro, New Caledonia Goro is a major mining settlement in South Province, New Caledonia. The Goro mine is one of the world's biggest nickel mines.

Gobiiformes
Gobiiformes (meaning "goby-like") is an order of percomorph fish containing three suborders: Apogonoidei, Trichonotoidei, and Gobioidei. The order was formerly defined as containing only the gobies (now placed within the Gobioidei). However, more recent taxonomic treatments also place their close relatives (the cardinalfishes, nurseryfishes, and sand-divers) with them, based on phylogenetic studies that unexpectedly found a close relationship between these groups. The Gobioidei are the most speciose clade of the family. Despite the differing appearances of members of this group, all share the trait of adhesive eggs with elaborate structures. Many species within this group also display elaborate forms of parental care by the male. Gobiiforms are a relatively basal clade of the percomorphs, with only the ophidiiforms and batrachoidiforms being more basal. They are estimated to have diverged from the rest of the group during the early-to-mid Cretaceous (about 120 million ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
David Starr Jordan
David Starr Jordan (January 19, 1851 – September 19, 1931) was the founding president of Stanford University, serving from 1891 to 1913. He was an ichthyologist during his research career. Prior to serving as president of Stanford University, he served as president of Indiana University Bloomington, Indiana University from 1885 to 1891. Jordan was also a strong supporter of eugenics, and his published views expressed a fear of "race-degeneration", asserting that cattle and human beings are "governed by the same laws of selection". He was an antimilitarist since he believed that war killed off the best members of the gene pool, and he initially opposed American involvement in World War I. Early life and education Jordan was born in Gainesville (town), New York, Gainesville, New York, and grew up on a farm in upstate New York. His parents made an unorthodox decision to educate him at a local girls' high school. His middle name, Starr, does not appear in early census records, ...

Perciformes
Perciformes (), also called the Acanthopteri, is an order or superorder of ray-finned fish in the clade Percomorpha. ''Perciformes'' means " perch-like". Among the well-known members of this group are perches and darters ( Percidae), and also sea basses and groupers (Serranidae). This order contains many familiar freshwater temperate and tropical marine fish groups, but also extremophiles that have successfully colonized both the North and South Poles, as well as the deepest depths of the ocean. Taxonomy Formerly, this group was thought to be even more diverse than it is thought to be now, containing about 41% of all bony fish (about 10,000 species) and about 160 families, which is the most of any order within the vertebrates. However, many of these other families have since been reclassified within their own orders within the clade Percomorpha, significantly reducing the size of the group. In contrast to this splitting, other groups formerly considered distinct, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Guinea
New Guinea (; Hiri Motu: ''Niu Gini''; , fossilized , also known as Papua or historically ) is the List of islands by area, world's second-largest island, with an area of . Located in Melanesia in the southwestern Pacific Ocean, the island is separated from Mainland Australia, Australia by the wide Torres Strait, though both landmasses lie on the same continental shelf, and were united during episodes of low sea level in the Pleistocene glaciations as the combined landmass of Sahul. Numerous smaller islands are located to the west and east. The island's name was given by Spanish explorer Yñigo Ortiz de Retez during his maritime expedition of 1545 due to the perceived resemblance of the indigenous peoples of the island to those in the Guinea (region), African region of Guinea. The eastern half of the island is the major land mass of the nation of Papua New Guinea. The western half, known as Western New Guinea, forms a part of Indonesia and is organized as the provinces of Pap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

New Caledonia
New Caledonia ( ; ) is a group of islands in the southwest Pacific Ocean, southwest of Vanuatu and east of Australia. Located from Metropolitan France, it forms a Overseas France#Sui generis collectivity, ''sui generis'' collectivity of the French Republic, a legal status unique in overseas France, and is enshrined in a dedicated chapter of the French Constitution. The archipelago, part of the Melanesia subregion, includes the main island of Grande Terre (New Caledonia), Grande Terre, the Loyalty Islands, the Chesterfield Islands, the Belep archipelago, the Isle of Pines (New Caledonia), Isle of Pines, and a few remote islets. The Chesterfield Islands are in the Coral Sea. French people, especially locals, call Grande Terre , a nickname also used more generally for the entire New Caledonia. Kanak people#Agitation for independence, Pro-independence Kanak parties use the name (''pron.'' ) to refer to New Caledonia, a term coined in the 1980s from the ethnic name of the indi ...
