George Albert Boulenger was a Belgian-British zoologist who described and gave scientific names to over 2,000 new animal species, chiefly fish, reptiles, and amphibians. Boulenger was also an active botanist during the last 30 years of his life, especially in the study of roses.
The Sawtooth Wilderness is a federally-protected wilderness area that covers 217,088 acres (87,852 ha) of the state of Idaho. Managed by the U.S. Forest Service in the U.S. Department of Agriculture, it was designated the Sawtooth Primitive Area in 1937 to preserve the exceptional scenic beauty of the Sawtooth Mountains. On August 22, 1972 Public Law 92-400 designated the Primitive Area as the Sawtooth Wilderness and part of the newly created Sawtooth National Recreation Area. As part of the National Wilderness Preservation System, the Sawtooth Wilderness is an area where human development and use are restricted and people are to remain only visitors. According to the United States Environmental Protection Agency, the Sawtooth Wilderness has some of the clearest air in the lower 48 states.
Sawtooth National Forest is a National Forest that covers 2,110,408 acres in the U.S. states of Idaho and Utah. Managed by the U.S. Forest Service in the U.S. Department of Agriculture, it was originally named the Sawtooth Forest Reserve in a proclamation issued by President Theodore Roosevelt on May 29, 1905. On August 22, 1972 a portion of the forest was designated as the Sawtooth National Recreation Area (SNRA), which includes the Sawtooth, Cecil D. Andrus–White Clouds, and Hemingway–Boulders wilderness areas. The forest is managed as four units: the SNRA and the Fairfield, Ketchum, and Minidoka Ranger Districts.
Snipe eels are a family, Nemichthyidae, of eels that consists of nine species in three genera. They are pelagic fishes, found in every ocean, mostly at depths of 300–600 m (980–1,970 ft) but sometimes as deep as 4,000 m (13,000 ft). Depending on the species, adults may reach 1–2 m (39–79 in) in length, yet they weigh only 80–400 g (2.8–14.1 oz). They are distinguished by their very slender jaws that separate toward the tips as the upper jaw curves upward. The jaws appear similar to the beak of the bird called the snipe. Snipe eels are oviparous, and the juveniles, called Leptocephali, do not resemble the adults but have oval, leaf-shaped and transparent bodies. Different species of snipe eel have different shapes, sizes and colors. The similarly named bobtail snipe eel is actually in a different family and represented by two species, the black Cyema atrum and the bright red Neocyema erythrosoma.
Sawtooth eels are a family, Serrivomeridae, of eels found in temperate and tropical seas worldwide.
Dendrelaphis is a genus of colubrid snakes, distributed from Pakistan, India and southern China to Indonesia, Timor-Leste, the Philippines, Australia, New Guinea and the Solomon Islands. There are over forty described species. Asian species are known commonly as bronzebacks, while the Australo-Papuan species are simply called treesnakes. All are non-venomous and entirely harmless to humans.
Mastacembelus is a genus of many species of spiny eel fish from the family Mastacembelidae. They are native to Africa and Asia. Most are found in rivers and associated systems, but there are also species in other freshwater habitats and a particularly rich radiation is found in the Lake Tanganyika basin with 15 species. A few species can even occur in brackish water.
Synodontis is the largest genus of mochokid catfishes. It is the biggest genus within the 10 genera and 190 different species in the family Mochokidae. Synodontis has over 131 different species within the genus. Synodontis are also known as squeakers, due to their ability to make stridulatory sounds through their pectoral fin spines when handled or disturbed. Synodontis make a sound that sounds like squeaking by rubbing their spines together. They do this when they have been frightened or when they become angry. Synodontis may also squeak when they are taken out of the water. These catfish are small- to medium-sized fish with many species exhibiting attractive spotted markings. Some species are also known for naturally swimming belly-up, earning the name upside-down catfish. Some of these species are Synodontis contractus and Synodontis nigriventris. While some of these species are known to swim upside down, another species, Synodontis multipunctatus, is a brood parasitic cuckoo catfish,there are two other species Synodontis petricola and Synodontis grandiops are also called brood parasitic cuckoo catfish.
Haplochromis is a ray-finned fish genus in the family Cichlidae. It has been used as the default "wastebin taxon" for Pseudocrenilabrinae cichlids of the East African Rift, and as such became the "largest" fish "genus". Many of these cichlids are popular aquarium fishes; like similar Haplochromini they are known as "haplos", "happies" or "haps" among aquarium enthusiasts.
Raiamas is a genus of cyprinid freshwater fishes. The majority of the species are from Africa, but R. bola and R. guttatus are from South and Southeast Asia.
The Lake Tanganyika sardine is a species of freshwater fish in the family Dorosomatidae which was endemic to Lake Tanganyika but which has now been introduced to other lakes in Africa as a food source. It is monotypic within the genus Limnothrissa. It and the Lake Tanganyika sprat are known collectively as kapenta.
Labeobarbus is a mid-sized ray-finned fish genus in the family Cyprinidae. Its species are widely distributed throughout eastern Africa and especially southern Africa, but also in Lake Tana in Ethiopia. A common name, in particular for the southern species, is yellowfish. The scientific name refers to the fact that these large barbs remind of the fairly closely related "carps" in the genus Labeo in size and shape. As far as can be told, all Labeobarbus species are hexaploid.
Cladistia is a clade of bony fishes whose only living members are the bichirs. Their major synapomorphies are a heterocercal tail in which the dorsal fin has independent rays, and a posteriorly elongated parasphenoid.
Petrocephalus is a genus of ray-finned fish in the family Mormyridae. All the fish species of this genus are endemic to Africa.
Stomatorhinus is a genus of small elephantfish in the family Mormyridae.
Microthrissa is a genus of sprats in the herring family, Dorosomatidae, which is endemic to Africa. There are five recognized species in the genus.
Odaxothrissa, the fangtooth pellonulines, is a genus of fresh-water fish in the family Dorosomatidae. There are currently three recognized species in this genus, all of which are found in tropical Africa.
Microthrissa royauxi, the royal sprat, is a species of pelagic, freshwater fish from the herring family Clupeidae which is found in the Congo River basin in west Africa. It was described in 1902 by the Belgian-British zoologist George Albert Boulenger. It is of limited importance as a food fish in subsistence fisheries and its conservation status is Least Concern.
The bluntnosed sawtooth pellonuline, Potamothrissa obtusirostris is a fish species in the family Clupeidae. It is native to Central African Republic, Democratic Republic of the Congo and Republic of the Congo. The International Union for Conservation of Nature classifies this species as Least concern.
