Franz Steindachner
Franz Steindachner (11 November 1834 in Vienna – 10 December 1919 in Vienna) was an Austrian zoologist, ichthyologist, and herpetologist. He published over 200 papers on fishes and over 50 papers on reptiles and amphibians. Steindachner described hundreds of new species of fish and dozens of new amphibians and reptiles. At least seven species of reptile have been named after him. Work and career Being interested in natural history, Steindachner took up the study of fossil fishes on the recommendation of his friend Eduard Suess (1831–1914). In 1860 he was appointed to the position of director of the fish collection at the Natural History Museum, Vienna, a position which had remained vacant since the death of Johann Jakob Heckel (1790–1857). (in German). Steindachner's reputation as an ichthyologist grew, and in 1868 he was invited by Louis Agassiz (1807–1873) to accept a position at the Museum of Comparative Zoology at Harvard University.

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fish or actinopterygians, is a class of bony fish that comprise over 50% of living vertebrate species. They are so called because of their lightly built fins made of webbings of skin supported by radially extended thin bony spines called '' lepidotrichia'', as opposed to the bulkier, fleshy lobed fins of the sister clade Sarcopterygii (lobe-finned fish). Resembling folding fans, the actinopterygian fins can easily change shape and wetted area, providing superior thrust-to-weight ratios per movement compared to sarcopterygian and chondrichthyian fins. The fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the articulation between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). The vast majority of actinopterygians are teleosts. By species count, they dominate the subphylum Vertebrata, and constitute nearly 99% of the over 30,000 extant ...

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Ephippidae
Ephippidae is a family of percomorph fishes, the spadefishes, in the order Moroniformes. These fishes are found in the tropical and temperate oceans of the world, except for the central Pacific. Taxonomy Ephippidae was first proposed as a family in 1859 by the Dutch herpetologist and ichthyologist Pieter Bleeker. The 5th edition of the ''Fishes of the World'' classifies this family in the order Moroniformes with the Moronidae and Drepaneidae. Other authorities place this family alongside the Drepaneidae in the order Ephippiformes with the Moronidae classified as ''incertae sedis'' in the series Eupercaria. Other authorities classify all three families in the Moroniformes ''sensu'' ''Fishes of the World'' in the Acanthuriformes. Genera Ephippidae contains the following genera, 8 extant and 3 extinct ( means extinct): The extinct genus '' Exellia'' is classified within the Ephippidae by some authorities, other authorities place it in the family Exellidae.

Total Length
Fish measurement is the measuring of individual fish and various parts of their anatomies, for data used in many areas of ichthyology, including taxonomy and fishery biology. Overall length Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. This measurement excludes the length of the caudal (tail) fin. Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes ( lampreys) and usually Elasmobranchii (shark Sharks are a group of elasmobranch cartilaginous fish characterized by a ...

Ichthyologist
Ichthyology is the branch of zoology devoted to the study of fish, including bony fish (Osteichthyes), cartilaginous fish (Chondrichthyes), and jawless fish (Agnatha). According to FishBase, 35,800 species of fish had been described as of March 2025, with approximately 250 new species described each year. Etymology The word is derived from the Ancient Greek words wikt:ἰχθύς, ἰχθύς, ''ikhthus'', meaning "fish"; and wikt:-λόγος, λόγος, ''logos'', meaning "study". History The study of fish dates from the Upper Paleolithic, Upper Paleolithic Revolution (with the advent of "high culture"). The science of ichthyology was developed in several interconnecting epochs, each with various significant advancements. The study of fish receives its origins from humans' desire to feed, clothe, and equip themselves with useful implements. According to Michael Barton (professor), Michael Barton, a prominent ichthyologist and professor at Centre College, "the earliest ichthy ...

Type Locality (biology)
In biology, a type is a particular wikt:en:specimen, specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally associated. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set (mathematics), set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN), the ...

Freetown
Freetown () is the Capital city, capital and largest city of Sierra Leone. It is a major port city on the Atlantic Ocean and is located in the Western Area of the country. Freetown is Sierra Leone's major urban, economic, financial, cultural, educational and political centre, as it is the seat of the Government of Sierra Leone. The population of Freetown was 1,347,559 as of the 2024 census. The city's economy revolves largely around its harbour, which occupies a part of the estuary of the Sierra Leone River in one of the world's largest natural deep water harbours.

The city is home to a significant population of all of Sierra Leone's Ethnic groups in Sierra Leone, ethnic groups, with no single ethnic group forming more than 27% of the city's population. As in virtually all parts of Sierra Leone, the Krio language ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet, species epithet, or epitheton) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Etymology Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the ...

Chaetodipterus
''Chaetodipterus'' is a genus of marine ray-finned fishes belonging to the family Ephippidae, the spadefishes. These fishes are found in the Atlantic and eastern Pacific Oceans. Taxonomy ''Chaetodipterus'' was first proposed as a monospecific genus in 1802 by the French naturalist Bernard Germain de Lacépède with ''Chaetodon plumieri'', a species described by Marcus Elieser Bloch on 1787 from Jamaica, as its only species. ''Chaetodon plumieri'' is a synonym of ''Chaetodipterus faber''. This genus is classified within the family Ephippidae which is in the order Moroniformes. Etymology ''Chaetodipterus'' is a combination of ''di'', meaning "two", and ''pterus'', meaning "fin", prefixed with ''Chaetodon''. This is a reference to the original genus the type species was assigned to but with a split dorsal fin. Species ''Chaetodipterus'' contains three recognized species: *'' Chaetodipterus faber'' (Broussonet, 1782) (Atlantic spadefish) *'' Chaetodipterus lippei'' Steindachner, 18 ...
