James Erwin Böhlke
James Erwin Böhlke (1930–1982) was an American ichthyologist. From 1954 to 1982, he was curator of the Department of Ichthyology at the Academy of Natural Sciences of Philadelphia (today the Academy of Natural Sciences of Drexel University). He published over 120 papers on diverse groups of fishes and topics, primarily in his areas of expertise, fishes of the Bahamas, Caribbean, and South America. His wife Eugenia (Genie) Brandt Böhlke (1928–2001) was also a noted ichthyologist. The serranid fish genus ''Jeboehlkia ''Jeboehlkia'' is a monotypic genus of marine ray-finned fish, related to the groupers and classified within the subfamily Epinephelinae of the family Serranidae.

Halftooth
The Hemiodontidae are a small family of freshwater characins found in northern South America, south to the Paraná-Paraguay Basin. The larger species are popular food fish. Hemiodontids have a streamlined body shape; many are fast-swimming, and are able to leap out of the water to escape predators. The adults of all species except ''Micromischodus sugillatus'' have no teeth on their lower jaws. Most species have a round spot on the side of the midbody and a stripe along the lower lobe of the caudal fin. The largest hemiodontids are around in length. Fossil remains of ''Hemiodus'' are known from the Middle Miocene-aged Pebas Formation of Peru. Genera The family has around 29 known species, as well as several undescribed species, in five genera: *''Anodus'' Cuvier, 1829 *''Argonectes'' Böhlke & Myers, 1956 *''Bivibranchia'' Eigenmann, 1912 *''Hemiodus'' Müller, 1842 *''Micromischodus'' Roberts, 1971 References *Nelson, Joseph S.

Tropical
The tropics are the regions of Earth surrounding the equator, where the sun may shine directly overhead. This contrasts with the temperate or polar regions of Earth, where the Sun can never be directly overhead. This is because of Earth's axial tilt; the width of the tropics (in latitude) is twice the tilt. The tropics are also referred to as the tropical zone and the torrid zone (see geographical zone). Due to the overhead sun, the tropics receive the most solar energy over the course of the year, and consequently have the highest temperatures on the planet. Even when not directly overhead, the sun is still close to overhead throughout the year, therefore the tropics also have the lowest seasonal variation on the planet; "winter" and "summer" lose their temperature contrast. Instead, seasons are more commonly divided by precipitation variations than by temperature variations. The tropics maintain wide diversity of local climates, such as rain forests, monsoons, sa ...

South America
South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a considerably smaller portion in the Northern Hemisphere. It can also be described as the southern Subregion#Americas, subregion of the Americas. South America is bordered on the west by the Pacific Ocean, on the north and east by the Atlantic Ocean, and to the south by the Drake Passage; North America and the Caribbean Sea lie to the northwest. The continent includes twelve sovereign states: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela; two dependent territory, dependent territories: the Falkland Islands and South Georgia and the South Sandwich Islands; and one administrative division, internal territory: French Guiana. The Dutch Caribbean ABC islands (Leeward Antilles), ABC islands (Aruba, Bonaire, and Curaçao) and Trinidad and Tobago are geologically located on the South-American continental shel ...

Rudolf Kner
Rudolf Ignaz Kner (24 August 1810 – 27 October 1869) was an Austrian geologist, paleontologist, zoologist and ichthyologist. He also wrote some poems which were published by his brother-in-law K.A. Kaltenbrunner. Biography Kner was born in Linz where his father Johann Evangelist Georg Kner (1763-1845) was a tax officer. His mother Barbara (1770-1825), daughter of forester Johann von Adlersburg was earlier married to apothecary Felix Gulielmo until his death. Barbara had a daughter Marie Gulielmo from her earlier marriage before having Rudolf and his sister Pauline. Pauline Anna Barbara Kner (1809-1843) married the Austrian poet Karl Adam Kaltenbrunner (1804-1867) in 1834. Rudolf studied in the secondary school in Linz from 1818 and the high school from 1821. During this period he was encouraged in the natural sciences with a gift of minerals from his uncle Hallstatt Maximilian Kner (1755–1821). From 1823 he went to the Stiftsgymnasium Kremsmünster. His godfather, Ign ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Characiformes Genera
Characiformes is an order of Actinopterygii, ray-finned fish, comprising the characins and their allies. Grouped in 18 recognized families, more than 2000 different species are described, including the well-known piranha and tetras.; Buckup P.A.: "Relationships of the Characidiinae and phylogeny of characiform fishes (Teleostei: Ostariophysi)", ''Phylogeny and Classification of Neotropical Fishes'', L.R. Malabarba, R.E. Reis, R.P. Vari, Z.M. Lucena, eds. (Porto Alegre: Edipucr) 1998:123-144. Taxonomy The Characiformes form part of a series called the Ostariophysi, Otophysi within the superorder Ostariophysi. The Otophysi contain three other orders, Cypriniformes, Siluriformes, and Gymnotiformes. The Characiformes form a group known as the Characiphysi with the Siluriformes and Gymnotiformes. The order Characiformes is the sister group to the orders Siluriformes and Gymnotiformes, though this has been debated in light of recent molecular evidence. Originally, the characins were ...

Fish Of South America
A fish (: fish or fishes) is an aquatic animal, aquatic, Anamniotes, anamniotic, gill-bearing vertebrate animal with swimming fish fin, fins and craniate, a hard skull, but lacking limb (anatomy), limbs with digit (anatomy), digits. Fish can be grouped into the more basal (phylogenetics), basal jawless fish and the more common jawed fish, the latter including all extant taxon, living cartilaginous fish, cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single Class (biology), class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are ectotherm, cold-blooded, their body temperature varying with the surrounding water, though some large nekton, active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communication in aquatic animals#Acoustic, communicate acoustically with each other, such as during courtship displays. The stud ...
