Diu Diu Cave
Diu Diu Cave is a karst cave located in Waigani, Milne Bay Province, Papua New Guinea. Traversing through the cave is very difficult; it involves wading through mud and guano with a low ceiling that at times dips to 80cm clearance. The cave is home to a population of blind cave eel, cave prawn, cave spiders and various species of bats, including flying fox ''Pteropus'' (suborder Yinpterochiroptera) is a genus of megabats which are among the largest bats in the world. They are commonly known as fruit bats or flying foxes, among other colloquial names. They live in South Asia, Southeast Asia, Aust ...es.

Milne Bay Province
Milne Bay is a province of Papua New Guinea. Its capital is Alotau. The province covers 14,345 km² of land and 252,990 km² of sea, within the province there are more than 600 islands, about 160 of which are inhabited. The province has about 276,000 inhabitants, speaking about 48 languages, most of which belong to the Eastern Malayo-Polynesian branch of the Austronesian language family. Economically the province is dependent upon tourism, oil palm, and gold mining on Misima Island; in addition to these larger industries there are many small-scale village projects in cocoa and copra cultivation. The World War II Battle of Milne Bay took place in the province. Culturally the Milne Bay region is sometimes referred to as "the Massim," a term originating from the name of Misima Island. Massim societies are usually characterized by matrilineal descent, elaborate mortuary sequences and complex systems of ritual exchange including the Kula ring. From island group to isla ...

Karst
Karst is a topography formed from the dissolution of soluble rocks such as limestone, Dolomite (rock), dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes. However, in regions where the dissolved bedrock is covered (perhaps by debris) or confined by one or more superimposed non-soluble rock strata, distinctive karst features may occur only at subsurface levels and can be totally missing above ground. The study of ''paleokarst'' (buried karst in the stratigraphic column) is important in petroleum geology because as much as 50% of the world's hydrocarbon reserves are hosted in carbonate rock, and much of this is found in porous karst systems. Etymology The English word ''karst'' was borrowed from German language, German in the late 19th century, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Papua New Guinea
Papua New Guinea (abbreviated PNG; , ; tpi, Papua Niugini; ho, Papua Niu Gini), officially the Independent State of Papua New Guinea ( tpi, Independen Stet bilong Papua Niugini; ho, Independen Stet bilong Papua Niu Gini), is a country in Oceania that comprises the eastern half of the island of New Guinea and its offshore islands in Melanesia (a region of the southwestern Pacific Ocean north of Australia). Its capital, located along its southeastern coast, is Port Moresby. The country is the world's third largest island country, with an area of . At the national level, after being ruled by three external powers since 1884, including nearly 60 years of Australian administration starting during World War I, Papua New Guinea established its sovereignty in 1975. It became an independent Commonwealth realm in 1975 with Elizabeth II as its queen. It also became a member of the Commonwealth of Nations in its own right.

Blind Cave Eel
The blind cave eel (''Ophisternon candidum'') is a species of cavefish in the family Synbranchidae. It is the longest cavefish in Australia (up to ) and one of the only three vertebrates in Australia that is restricted to underground waters, the other being the blind gudgeon (''Milyeringa veritas'') and the Barrow cave gudgeon (''Milyeringa justitia''). It is blind, its body is eel-like and elongated, and it has a non-pigmented skin with colours ranging from white to pink. The blind cave eel is endemic to northwestern Australia, specifically in the Cape Range region, the Pilbara Region, and the Barrow Island region. It is rarely spotted due to its habitat and has only been spotted 36 times from 1959 to 2017. Notably, there is an evolving independent parentage in the Pilbara region showing a significant genetic difference from other blind cave eels. The blind cave eel lives in a total darkness environment in underground waters disconnecting from the surface seawater. The ...

Prawn
Prawn is a common name for small aquatic crustaceans with an exoskeleton and ten legs (which is a member of the order decapoda), some of which can be eaten. The term "prawn"Mortenson, Philip B (2010''This is not a weasel: a close look at nature's most confusing terms''Pages 106–109, John Wiley & Sons. . is used particularly in the United Kingdom, Ireland, and Commonwealth nations, for large swimming crustaceans or shrimp, especially those with commercial significance in the fishing industry. Shrimp that are present in this category often belong to the suborder Dendrobranchiata. In North America, the term is used less frequently, typically for freshwater shrimp. The terms shrimp and prawn themselves lack scientific standing. Over the years, the way they are used has changed, and in contemporary usage the terms are almost interchangeable. Shrimp'' vs. ''prawn Regional distinctions The terms shrimp and prawn originated in Britain. In the use of common names for species, shrimp ...

Cave Spider
''Meta menardi'', the European cave spider, is a long-jawed orb-weaving spider (family Tetragnathidae). It is also known as the orbweaving cave spider, the cave orbweaver and, in context, simply the cave spider. Habitat They have a natural range extending from Scandinavia to North Africa and from Europe to Korea; there are also transplanted populations as far apart as Japan and Madagascar. The adult spiders are photophobic and live in places free from light, frequently in caves and tunnels, though they can sometimes be seen outside of caves and mines as they will emerge around dusk to hunt, often using a single silk lasso line and swinging down upon their prey. They are often found in areas that are frequented by bats. The spiders are most often observed in railway tunnels and mines since these are more likely to be visited by humans. The young spiders are, after several instars (and in contrast to the adults), strongly attracted to light—probably an evolutionary adaptati ...

Bats
Bats are mammals of the order Chiroptera.''cheir'', "hand" and πτερόν''pteron'', "wing". With their forelimbs adapted as wings, they are the only mammals capable of true and sustained flight. Bats are more agile in flight than most birds, flying with their very long spread-out digits covered with a thin membrane or patagium. The smallest bat, and arguably the smallest extant mammal, is Kitti's hog-nosed bat, which is in length, across the wings and in mass. The largest bats are the flying foxes, with the giant golden-crowned flying fox, ''Acerodon jubatus'', reaching a weight of and having a wingspan of . The second largest order of mammals after rodents, bats comprise about 20% of all classified mammal species worldwide, with over 1,400 species. These were traditionally divided into two suborders: the largely fruit-eating megabats, and the echolocating microbats. But more recent evidence has supported dividing the order into Yinpterochiroptera and Yangochiropt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flying Fox
''Pteropus'' (suborder Yinpterochiroptera) is a genus of megabats which are among the largest bats in the world. They are commonly known as fruit bats or flying foxes, among other colloquial names. They live in South Asia, Southeast Asia, Australia, East Africa, and some oceanic islands in the Indian and Pacific Oceans. There are at least 60 extant species in the genus. Flying foxes eat fruit and other plant matter, and occasionally consume insects as well. They locate resources with their keen sense of smell. Most, but not all, are nocturnal. They navigate with keen eyesight, as they cannot echolocate. They have long life spans and low reproductive outputs, with females of most species producing only one offspring per year. Their slow life history makes their populations vulnerable to threats such as overhunting, culling, and natural disasters. Six flying fox species have been made extinct in modern times by overhunting. Flying foxes are often persecuted for their real or ...
