Chlamydogobius Ranunculus
''Chlamydogobius'' is a genus of gobies from Australia. All but one coastal species (''C. ranunculus'') are found in inland waters, such as springs, pools, creeks and streams. Most species live in extreme environments; for example, several species of ''Chlamydogobius'' are found in the water that emerges from geothermal springs, such as the Dalhousie goby, found in the waters around Dalhousie Springs. These fish can live in water with a wide range of temperatures, pH, salinity, and oxygen levels; for example they are found in water with a pH between 6.8 and 9.0, and temperatures between . They can tolerate salinity as high as 60 parts per thousand (almost twice that of sea water). They have been found in water with extremely low oxygen levels (as low as 0.8 ppm). Their water habitats often exhibit oxygen levels below 5 milligrams of oxygen per litre. To cope with extremely low oxygen levels, they will emerge from the water to "gulp" air (known as aerial respiration). They als ...

Gilbert Percy Whitley
Gilbert Percy Whitley (9 June 1903 – 18 July 1975) was a British-born Australian ichthyologist and malacologist who was Curator of Fishes at the Australian Museum in Sydney for about 40 years. He was born at Swaythling, Southampton, England, and was educated at King Edward VI School, Southampton and the Royal Naval College, Osborne. Whitley migrated with his family to Sydney in 1921 and he joined the staff of the Australian Museum in 1922 while studying zoology at Sydney Technical College and the University of Sydney. In 1925 he was formally appointed Ichthyologist (later Curator of Fishes) at the Museum, a position he held until retirement in 1964. During his term of office he doubled the size of the ichthyological collection to 37,000 specimens through many collecting expeditions. Whitley was also a major force in the Royal Zoological Society of New South Wales, of which he was made a Fellow in 1934 and where he served as president during 1940–41, 1959–60 and 1973–74. ...

Aquifer
An aquifer is an underground layer of water-bearing, permeable rock, rock fractures, or unconsolidated materials (gravel, sand, or silt). Groundwater from aquifers can be extracted using a water well. Aquifers vary greatly in their characteristics. The study of water flow in aquifers and the characterization of aquifers is called hydrogeology. Related terms include aquitard, which is a bed of low permeability along an aquifer, and aquiclude (or ''aquifuge''), which is a solid, impermeable area underlying or overlying an aquifer, the pressure of which could create a confined aquifer. The classification of aquifers is as follows: Saturated versus unsaturated; aquifers versus aquitards; confined versus unconfined; isotropic versus anisotropic; porous, karst, or fractured; transboundary aquifer. Challenges for using groundwater include: overdrafting (extracting groundwater beyond the Dynamic equilibrium, equilibrium yield of the aquifer), groundwater-related subsidence of land, gro ...

Helen Kay Larson
Helen K. Larson is an ichthyologist who specialises in the fishes of the Indo-Pacific. In the 1960s and 1970s, she attended the University of Guam to study for her Bachelor's and master's degrees and while there she also worked in the local Marine Laboratory. While there she collected and described a new species of the dwarf goby from the genus '' Eviota'', '' Eviota pellucida'', the description being published in 1976 in the journal ''Copeia''. This was her first description of a new species. Her Masters was called ''Notes on the biology and comparative behaviour of ''Eviota zonura'' and ''Eviota smaragdus'' (Pisces:Gobiidae)''. She gained a PhD in Zoology from the University of Queensland and her thesis was ''A revision of the gobiid fish genus ''Mugilogobius'' (Teleostei: Gobioidei), and its systematic placement''. She moved from Guam in 1974 to work with Douglass F. Hoese at the Australian Museum in Sydney as a Technical Officer and in 1981 she took a position as Curat ...

Chlamydogobius Gloveri
The Dalhousie goby (''Chlamydogobius gloveri'') is a species of goby endemic to Australia where it lives in the Dalhousie Springs. This species can reach a standard length of . It feeds on small molluscs, crustaceans and other odds and ends like most other gobies. Etymology The scientific name "Chlamydogobius gloveri" is derived from the Greek word "chlamys" meaning cloak, whilst the word "gobius" is defined as gudgeon in Latin.> The second half of the species is named "gloveri" in honour of the late John Glover, a former Curator of Fishes at the South Australian Museum, who worked extensively on desert gobies and other taxa of fishes found in the deserts of Australia. Glover was sure that this goby was a distinct species from '' Chlamydogobius eremius'' but he did not describe it. The species was documented throughout the 1980s and Charles Glover specifically wrote about the fish in 1989. Prominent Australian ichthyologist, Helen K Larson, also documented this species in ...

Adaptive Camouflage
Active camouflage or adaptive camouflage is camouflage that adapts, often rapidly, to the surroundings of an object such as an animal or military vehicle. In theory, active camouflage could provide perfect concealment from visual detection. Active camouflage is used in several groups of animals, including reptiles on land, and cephalopod molluscs and flatfish in the sea. Animals achieve active camouflage both by color change and (among marine animals such as squid) by counter-illumination, with the use of bioluminescence. Military counter-illumination camouflage was first investigated during the Second World War for marine use. More recent research has aimed to achieve crypsis by using cameras to sense the visible background, and by controlling Peltier panels or coatings that can vary their appearance. In animals Active camouflage is used in several groups of animals including cephalopod molluscs, fish, and reptiles. There are two mechanisms of active camouflage in animals: ...
