Lake Tanganyika is an African Great Lake. It is the second-oldest freshwater lake in the world, the second-largest by volume, and the second-deepest, in all cases after Lake Baikal in Siberia. It is the world's longest freshwater lake. The lake is shared among four countries—Tanzania, the Democratic Republic of the Congo (DRC), Burundi, and Zambia, with Tanzania (46%) and DRC (40%) possessing the majority of the lake. It drains into the Congo River system and ultimately into the Atlantic Ocean.
The archerfish form a monotypic family, Toxotidae, of fish known for their habit of preying on land-based insects and other small animals by shooting them down with water droplets from their specialized mouths. The family is small, consisting of ten species in a single genus, Toxotes. Most species live in fresh water rivers, streams and pools, but two or three are euryhaline, inhabiting both fresh and brackish water habitats such as estuaries and mangroves. They can be found from India, Bangladesh and Sri Lanka, through Southeast Asia, to Northern Australia and Melanesia.
The New Zealand longfin eel is a species of freshwater eel that is endemic to New Zealand. It is the largest freshwater eel in New Zealand and the only endemic species – the other eels found in New Zealand are the native shortfin eel, also found in Australia, and the naturally introduced Australian longfin eel. Longfin eels are long-lived, migrating to the Pacific Ocean near Tonga to breed at the end of their lives. They are good climbers as juveniles and so are found in streams and lakes a long way inland. An important traditional food source for Māori, longfin eels numbers are declining and they are classified as endangered, but over one hundred tonnes are still commercially fished each year.
The largemouth yellowfish or Vaal-Orange largemouth yellowfish is a ray-finned fish species in the family Cyprinidae. This large freshwater barb is found in southern Africa.
The northern snake-necked turtle or northern long-necked turtle is a species of turtle in the family Chelidae or Austro-South American Side-necked Turtles. It is native to northern Australia and southern New Guinea.
Hypseleotris kimberleyensis, the Barnett River gudgeon, is a species of fish in the family Eleotridae endemic to Australia, where it is only known from the Barnett River system of Kimberley, Western Australia. Its preferred habitat is rocky pools and streams. This species can reach a length of 6 cm (2.4 in).
The Kimberley grunter is a species of fish in the family Terapontidae. It is endemic to Australia, where it lives in the coastal rivers of northern Western Australia. It is known from the Durack, Pentecost, and Bow Rivers of the Kimberley region.
The Australian spotted mackerel is a species of fish in the family Scombridae. Common fork length ranges between 50 and 80 cm. Specimens have been recorded at up to 104 cm in length, and weighing up to 10.2 kg. It is found in the western Pacific, along the northern coast of Australia, from the Abrolhos Islands region of Western Australia to Coffs Harbour and Kempsey in central New South Wales. It is also found in southern Papua New Guinea from Kerema to Port Moresby. It feeds largely on fishes, particularly anchovies and sardines, with smaller quantities of shrimps and squids. It is sometimes confused with Japanese Spanish mackerel, S. niphonius. Conservation status of the species has been evaluated as Near Threatened by the IUCN. This species was described in 1980 and was previously confused with the Japanese Spanish mackerel of the north western Pacific but S. munroi has a different visceral structure, more vertebrae and fewer gill rakers.
The banded archerfish is a brackish water perciform fish of the archerfish genus Toxotes. It is silvery in colour and has a dorsal fin towards the posterior end. It has distinctive, semi-triangular markings along its sides. It is best known for its ability to spit a jet of water to "shoot down" prey. Larger specimens may be able to hit prey 2 to 3 metres away. The banded archerfish may reach the displaced prey within 50 milliseconds of its hitting the water.
Toxotes chatareus, sometimes known by the common names common archerfish, seven-spot archerfish or largescale archerfish, is a species of perciform fish in the archerfish genus Toxotes.
The smallscale archerfish is a perciform fish of genus Toxotes. As its name suggests, the scales of the smallscale archerfish are smaller than those of other archerfish. They reach a maximum length of 15 centimetres (5.9 in). Smallscale archerfish live in the tropical Indo-Pacific region and are potamodromous, moving between fresh and brackish water through their lifetimes.
Toxotes blythii, the clouded archerfish or zebra archerfish, is a perciform fish of genus Toxotes. It is found in rivers and estuaries in Myanmar, ranging from the lower Irrawaddy to the Tenasserim Division, including lower Sittaung and Salween. Unlike some other archerfish, it is restricted to fresh water. This species was formerly thought to be identical to T. microlepis. However, differences in structure and colouration caused the splitting of T. blythii into a new species. It is sometimes seen in the aquarium trade, but is generally rare.
Protoxotes lorentzi is a tropical freshwater fish found in streams and swamps of the Northern Territory of Australia, Irian Jaya (Indonesia), and Papua New Guinea. It was first named by Weber in 1910, and is commonly known as the primitive archerfish or Lorentz's archerfish.
Toxotes kimberleyensis is a species of archerfish found in the Kimberley region of Western Australia. It was first named by Gerald R. Allen in 2004, and is commonly known as the Kimberley archerfish, largescale archerfish, or western archerfish.
Oligolepis acutipennis, the sharptail goby, is a species of goby native to marine, freshwater and brackish waters along the coasts of Indo-West Pacific region. This species can reach a length of 12 centimetres (4.7 in) TL.
Cyrtodactylus kimberleyensis, also known as the Kimberley bent-toed gecko or East Montalivet Island gecko, is a species of gecko that is endemic to East Montalivet Island in Western Australia.
Albula oligolepis is a species of marine fish found in the Indo-West Pacific. It is known commonly as the smallscale bonefish. They grow up to 32 cm (13 in).
Nothobranchius albertinensis is a species of brightly colored seasonal killifish in the family Nothobranchiidae. This species is endemic to seasonal freshwater habitats in north-western Uganda. It is currently known from ephemeral pools and marshes associated with the Albert Nile drainage, as well as small river systems draining into the north-eastern part of Lake Albert.
Nothobranchius attenboroughi is a species of brightly colored seasonal killifish in the family Nothobranchiidae. It is endemic to Tanzania. It is currently known from ephemeral pools and marshes associated with the Grumeti River and other small systems draining into Lake Victoria at the east side of the lake, which ecological integrity is maintained by the congruence of its catchments largely within the Serengeti-Mara ecosystem.
