Callopanchax occidentalis is a species of killifish in the family Nothobranchiidae. It is endemic to Sierra Leone and western Liberia.
The species is an annual killifish whose eggs survive in the mud during the dry season. [2] It inhabits pools, swampy sections of streams and temporary swamps in rainforest and forested savannah, feeding on small invertebrates. [1]
A killifish is any of various oviparous (egg-laying) cyprinodontiform fish. All together, there are 1,270 species of killifish, the biggest family being Rivulidae, containing more than 320 species. As an adaptation to living in ephemeral waters, the eggs of most killifish can survive periods of partial dehydration. Many of the species rely on such a diapause, since the eggs would not survive more than a few weeks if entirely submerged in water. The adults of some species, such as Kryptolebias marmoratus, can additionally survive out of the water for several weeks. Most killies are small fish, from 2.5 to 5 cm, with the largest species growing to just under 15 cm.
Nothobranchius is a genus of small, freshwater killifish, classified in either the family Nothobranchiidae or a more inclusive Aplocheilidae in the order Cyprinodontiformes. There are many species: as of 2018 there are more than 70 species, many with very small distributions. They are primarily native to East Africa from Sudan to northern South Africa, but half a dozen species are found in the upper Congo River Basin and two species are from west-central Africa; the greatest species richness is in Tanzania.
The night parrot is a small parrot endemic to the continent of Australia. It has also been known as porcupine parrot, nocturnal ground parakeet, midnight cockatoo, solitaire, spinifex parrot and night parakeet. It is one of the most elusive and mysterious birds in the world, with no confirmed sightings of the bird between 1912 and 1979, leading to speculation that it was extinct. Sightings since 1979 have been extremely rare and the bird's population size is unknown, though based on the paucity of records it is thought to number between 50 and 249 mature individuals, and it is classified by the IUCN as an endangered species.
The Ash Meadows killifish is a species of killifish from the subfamily Empetrichthyinae, part of the family Goodeidae, which was first documented by C. H. Gilbert in 1893 and historically occupied numerous springs near Ash Meadows, Nye County, Nevada, United States. This species was last seen in 1948 and is believed to have gone extinct in the early 1950s, likely as a result of habitat alteration and competition with and predation by introduced crayfish Procambarus clarkii, mosquitofish, black mollies, and bullfrogs.
Fundulus is a genus of ray-finned fishes in the superfamily Funduloidea, family Fundulidae. It belongs to the order of toothcarps (Cyprinodontiformes), and therein the large suborder Cyprinodontoidei. Most of its closest living relatives are egg-laying, with the notable exception of the splitfin livebearers (Goodeidae).
Banksia occidentalis, commonly known as the red swamp banksia, is a species of shrub or small tree that is endemic to the south coast of Western Australia. It has smooth bark, linear, sparsely serrated leaves, golden flowers in a cylindrical spike, and later up to sixty follicles in each spike.
The striped panchax is a species of killifish, of the genus Aplocheilus. An aquarium variant of this species with a more yellowish coloration is known as golden wonder killifish. The striped panchax inhabits fresh and brackish waters of India and Sri Lanka. It is found in streams, rivers, swamps, and paddy fields. This fish grows to a length of 10 cm (3.9 in).
The banded killifish is a North American species of temperate freshwater killifish belonging to the genus Fundulus of the family Fundulidae. Its natural geographic range extends from Newfoundland to South Carolina, and west to Minnesota, including the Great Lakes drainages. This species is the only freshwater killifish found in the northeastern United States. While it is primarily a freshwater species, it can occasionally be found in brackish water.
The spotted killifish is a small, short lived species of fish, an African rivuline from the family Nothobranchiidae. These fish are native to many isolated freshwater pools located in the savannah depressions of east Africa, specifically Malawi, Mozambique, Zimbabwe, and South Africa. This species of fish occurs in ephemeral waters and killifish eggs can survive long periods of dehydration. The word killifish likely comes from the Dutch kil for kill.
Nothobranchius kafuensis, known as the Caprivi killifish or Kafue killifish, is a species of killifish in the family Nothobranchiidae. This killifish is found in temporary pools, swamps and ditches in the floodplains of the Kafue and Upper Zambezi rivers in western Zambia and the Caprivi Strip in Namibia.
The blue lyretail, also known as steel-blue aphyosemion and Gardner's killi. It is a species of killifish from Nigeria and Cameroon.
Euplassa occidentalis is a species of plant in the family Proteaceae. It is endemic to Ecuador.
Nothobranchius furzeri, the turquoise killifish, is a species of killifish from the family Nothobranchiidae native to Africa where it is only known from Zimbabwe and Mozambique. This annual killifish inhabits ephemeral pools in semi-arid areas with scarce and erratic precipitations and have adapted to the routine drying of their environment by evolving desiccation-resistant eggs that can remain dormant in the dry mud for one and maybe more years by entering into diapause. Due to very short duration of the rain season, the natural lifespan of these animals is limited to a few months and their captive lifespan is likewise short, making them an attractive model system for ageing and disease research. Tandem repeats comprise 21% of the species' genome, an abnormally high proportion, which has been suggested as a factor in its fast ageing. Among vertebrates, the species has the fastest known sexual maturity – only 14 days after hatching, and shortest lifespan – ranging 3 to 12 months depending on the environment. More specifically, they are able to live 1–5 months in the wild and 3–16 months in captivity. They are able to live longer in captivity due to their diet, which is mostly bloodworms; this is due to dietary restrictions and antioxidant resveratrol supplements.
Nothobranchius rachovii, or the bluefin notho, is a species of freshwater annual killifish from Mozambique. It can grow up to 6 cm (2.4"). It is popular among killifish enthusiasts, who raise them from eggs in aquaria.
Aphyosemion is a genus of African rivulines endemic as the name indicates to Africa. Many of these species are popular aquarium fish.
Callopanchax is a genus of African rivulines endemic, as the name indicates, to Africa. Some of these species are popular aquarium fish.
The Gulf killifish is one of the largest members of the genus Fundulus; it is capable of growing up to 18 cm in length, whereas the majority of other Fundulus reach a maximum length of 10 cm. Therefore, F. grandis is among the largest minnows preyed upon by many sport fish, such as flounder, speckled trout, and red drum. Fundulus derives from the Latin meaning "bottom," and grandis means "large". The Gulf killifish is native to the Gulf of Mexico from Texas to Florida and the eastern coast of Florida and the Caribbean Sea in the Atlantic Ocean. Threats to the survival of the Gulf killifish include extreme changes in salinity, changes in temperatures, and toxic events such as the hypoxic dead zone in Louisiana and the Deepwater Horizon oil spill. The Gulf killifish is currently being used to test the effects of oil and oil dispersants on the physiology of marine species affected by these substances. This is significant to conservation biology, because with the continued extraction of oil and other natural resources from North American waters, it has become increasingly important to understand the risks and consequences in worst-case scenarios, such as the Deepwater Horizon oil spill, and the lasting effects on the marine ecosystem.
The bayou killifish or bayou topminnow is a topminnow-like fish that thrives primarily in the shallow waters off the shores of the Americas, as well as fresh and brackish waters. Feeding off of small vertebrates and invertebrates, this fish displays reproduction techniques unique to its species.
The western round-eared bat is a bat species found only on the Pacific coast of northwestern Ecuador.
Protea madiensis, commonly known as the tall woodland sugarbush, is a flowering shrub which belongs to the genus Protea. It is native to the montane grasslands of Sub-Saharan Africa.
