Vatusila Tongensis
''Vatusila'' is a genus of land snail found in Oceania. It consists of five extant and one fossil species. Alan Solem described and named the genus in 1983. Taxonomic history The genus was circumscribed by the American malacologist Alan Solem in a 1983 monograph. He placed it in the subfamily Charopinae. Solem included six species in his original circumscription: ''V. eniwetokensis'', ''V. kondoi'', ''V. nayauana'', ''V. niueana'', ''V. tongensis'', and ''V. vaitupuensis''. Solem designated ''V. tongensis'' to be the genus's type species. The fossil species ''V. eniwetokensis'' was first described in 1958 by the American paleontologist Harry S. Ladd, who placed it in the genus '' Ptychodon''; Solem described the five other extant species in his 1983 monograph. The generic name ''Vatusila'' comes from a Fijian tribe of the same name which were located in the headwaters of the Sigatoka River on the island of Viti Levu. They are known for the 1867 murder and cannibalism of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sculpture (mollusc)
Sculpture is a feature of many of the shells of mollusks. It is three-dimensional ornamentation on the outer surface of the shell, as distinct from either the basic shape of the shell itself or the pattern of colouration, if any. Sculpture is a feature found in the shells of gastropods, bivalves, and scaphopods. The word "sculpture" is also applied to surface features of the aptychus of ammonites, and to the outer surface of some calcareous opercula of marine gastropods such as some species in the family Trochidae. Sculpture can be concave or convex, incised into the surface or raised from it. Sometimes the sculpture has microscopic detailing. The term "sculpture" refers only to the calcareous outer layer of shell, and does not include the proteinaceous periostracum, which is in some cases textured even when the underlying shell surface is smooth. In many taxa, there is no sculpture on the shell surface at all, apart from the presence of fine growth lines. The sculpture ...

Neogene
The Neogene ( ), informally Upper Tertiary or Late Tertiary, is a geologic period and system that spans 20.45 million years from the end of the Paleogene Period million years ago ( Mya) to the beginning of the present Quaternary Period Mya. The Neogene is sub-divided into two epochs, the earlier Miocene and the later Pliocene. Some geologists assert that the Neogene cannot be clearly delineated from the modern geological period, the Quaternary. The term "Neogene" was coined in 1853 by the Austrian palaeontologist Moritz Hörnes (1815–1868). During this period, mammals and birds continued to evolve into modern forms, while other groups of life remained relatively unchanged. The first humans (''Homo habilis'') appeared in Africa near the end of the period. Some continental movements took place, the most significant event being the connection of North and South America at the Isthmus of Panama, late in the Pliocene. This cut off the warm ocean currents from the Pacific to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marshall Islands
The Marshall Islands ( mh, Ṃajeḷ), officially the Republic of the Marshall Islands ( mh, Aolepān Aorōkin Ṃajeḷ),'' () is an independent island country and microstate near the Equator in the Pacific Ocean, slightly west of the International Date Line.

Tonga is about from New Zealand's North Island. First inhabited roughly 2,500 years ago by the Lapita civilization, Tonga's Polynesian settlers gradually evolved a distinct and strong ethnic identity, language, and culture as the Tongan people. They were quick to establish a powerful footing acr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ʻEua
Eua is an island in the kingdom of Tonga. It is close to Tongatapu, but forms a separate administrative division. It has an area of , and a population in 2021 of 4,903 people. Geography Eua is a hilly island, the highest peaks are the ''Teemoa'' (chicken manure) 312 m, and the ''Vaiangina'' (watersprings) 305 m. The island is not volcanic, but was shaped by the rubbing of the Tonga Plate against the Pacific Plate, pushing Eua up and leaving the Tonga Trench on the bottom of the ocean, a short distance towards the east. The soil of Eua is volcanic, as is that of Tongatapu, but only the top layer, deposited by eruptions of nearby volcanoes ten thousands years ago. Under it are the solid rocks of pushed-up coral. Eua counts many huge caves and holes, not all of which have yet been explored. Eua and Niuatoputapu are the only islands in Tonga that have streams, and ʿEua had the only bridge in the kingdom until Vavau also built one. The stream drains into the harbour n ...

Niue
Niue (, ; niu, Niuē) is an island country in the South Pacific Ocean, northeast of New Zealand. Niue's land area is about and its population, predominantly Polynesian, was about 1,600 in 2016. Niue is located in a triangle between Tonga, Samoa, and the Cook Islands. It is 604 kilometres northeast of Tonga. The island is commonly referred to as "The Rock", which comes from the traditional name "Rock of Polynesia". Niue is one of the world's largest coral islands. The terrain of the island has two noticeable levels. The higher level is made up of a limestone cliff running along the coast, with a plateau in the centre of the island reaching approximately 60 metres (200 feet) above sea level. The lower level is a coastal terrace approximately 0.5 km (0.3 miles) wide and about 25–27 metres (80–90 feet) high, which slopes down and meets the sea in small cliffs. A coral reef surrounds the island, with the only major break in the reef being in the central western c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fiji
Fiji ( , ,; fj, Viti, ; Fiji Hindi: फ़िजी, ''Fijī''), officially the Republic of Fiji, is an island country in Melanesia, part of Oceania in the South Pacific Ocean.

The interior of Viti Levu is sparsely inhabited because of its terrain. The majority of Fiji's islands were formed by Volcano, volcanic activity starting around 150 million years ago. Some geo ...

Lau Islands
The Lau Islands aka little Tonga (also called the Lau Group, the Eastern Group, the Eastern Archipelago) of Fiji are situated in the southern Pacific Ocean, just east of the Koro Sea. Of this chain of about sixty islands and islets, about thirty are inhabited. The Lau Group covers a land area of 188 square miles (487 square km), and had a population of 10,683 at the most recent census in 2007. While most of the northern Lau Group are high islands of volcanic origin, those of the south are mostly carbonate low islands. Administratively the islands belong to Lau Province. History The British explorer James Cook reached Vatoa in 1774. By the time of the discovery of the Ono Group in 1820, the Lau archipelago was the most mapped area of Fiji. Political unity came late to the Lau Islands. Historically, they comprised three territories: the Northern Lau Islands, the Southern Lau Islands, and the Moala Islands. Around 1855, the renegade Tongan prince Enele Ma'afu conquered the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
