Pseudorhabdosynochus Epinepheli
''Pseudorhabdosynochus epinepheli'' is a diplectanid monogenean parasitic on the gills of species of groupers. It is the type species of the genus '' Pseudorhabdosynochus'' Yamaguti, 1958. Description ''Pseudorhabdosynochus epinepheli'' is a small monogenean, about half a millimetre in length. Adults are hermaphroditic. The species has the general characteristics of other diplectanids, with a flat body and a posterior haptor, which is the organ by which the monogenean attaches itself to the gill of is host. The haptor bears two squamodiscs, one ventral and one dorsal, which are made up of numerous rows of rodlets. The reproductive organ include a single ovary and a single testis. The sclerotized male copulatory organ, or "quadriloculate organ", has the shape of a bean with four internal chambers, as in other species of '' Pseudorhabdosynochus''. The vagina also includes a sclerotized part, which is a complex structure. The sclerotised vagina comprises an anterior trumpet, fo ...

Fauna Of New Caledonia
The biodiversity of New Caledonia is of exceptional biological and paleoecological interest. It is frequently referred to as a biodiversity hotspot.Myers, Norman; Mittermeier, Russell A. ; Mittermeier, Cristina G.; da Fonseca, Gustavo A. B.; Kent, Jennifer. Biodiversity hotspots for conservation priorities. Nature 403, 853-858 (24 February 2000) , ; Received 22 September 1999 The country is a large South Pacific archipelago with a total land area of more than . The terrain includes a variety of reefs, atolls, small islands, and a variety of topographical and edaphic regions on the largest island, all of which promote the development of unusually concentrated biodiversity. The region's climate is oceanic and tropical. New Caledonia is separated from the nearest mainland by more than of open sea. Its isolation dates from at least the mid-Miocene, and possibly from the Oligocene, and that isolation has preserved its relict biota, fostering the evolution of wide ranges of endem ...

Fauna Of Japan
The wildlife of Japan includes its flora, fauna, and natural habitats. The islands of Japan stretch a long distance from north to south and cover a wide range of climatic zones. This results in a high diversity of wildlife despite Japan's isolation from the mainland of Asia. In the north of the country, north of Blakiston's Line, there are many subarctic species which have colonized Japan from the north. In the south there are south-east Asian species, typical of tropical regions. Between these areas lies the temperate zone which shares many species with China and Korea. Japan also has many endemic species that are found nowhere else in the world, making it home to many endangered/rare species. Fauna Mammals About 130 species of land mammal occur in Japan. The largest of these are the two bears. The Ussuri brown bear (''Ursus arctos'') is found in Hokkaidō, where it plays an important role in the culture of the Ainu people. The Asian black bear (''Ursus thibetanus'') inhabits ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animals Described In 1938
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinoderms and ...

China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia.

The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dyna ...

Epinephelus Chlorostigma 2
''Epinephelus'' is a genus of marine ray-finned fish, groupers from the subfamily Epinephelinae, part of the family Serranidae, which also includes the anthias and sea basses. They are predatory fish, largely associated with reefs and are found in tropical and subtropical seas throughout the world. They are important target species for fisheries.
