Hepsetus Odoe
''Hepsetus odoe'', the African pike characin, is a predatory freshwater characin belonging to the family Hepsetidae. It was formerly considered that there was a single species of ''Hepsetus'' pike characin but recent studies have led to the species being split and ''Hepsetus odoe'' ''sensu stricto'' is the west African representative of the group. Taxonomy Hepsetus odoe was first formally described as ''Salmo odoe'' in 1794 by the German naturalist Marcus Elieser Bloch with its type locality given as the "coast of Guinea", likely Togo or southeastern Ghana.> This species is the type species of the genus ''Hepsetus'' and was formerly believed to the only species in the genus and widespread in sub-Saharan Africa, but studies in 2011–2013 have found that there are several species, and the true ''H. odoe'' is restricted to West and Central Africa from the Sassandra River, Ivory Coast, to the Kienké River, Cameroon (species elsewhere are now recognized as separate; '' H. cuvieri' ...

Marcus Elieser Bloch
Marcus Elieser Bloch (1723–1799) was a German physician and naturalist who is best known for his contribution to ichthyology through his multi-volume catalog of plates illustrating the fishes of the world. Brought up in a Hebrew-speaking Jewish family, he learned German and Latin and studied anatomy before settling in Berlin as a physician. He amassed a large natural history collection, particularly of fish specimens. He is generally considered one of the most important ichthyologists of the 18th century, and wrote many papers on natural history, comparative anatomy, and physiology. Life Bloch was born at Ansbach in 1723 where his father was a Torah writer and his mother owned a small shop. Educated at home in Hebrew literature he became a private tutor in Hamburg for a Jewish surgeon. Here he learned German, Latin and anatomy. He then studied medicine in Berlin and received a doctorate in 1762 from Frankfort on the Oder with a treatise on skin disorders. He then became a ...

Hepsetus Lineata
''Hepsetus'' is a genus of freshwater ray-finned fishes belonging to the monotypic family Hepsetidae, the African pikes or African pike characins, in the order Characiformes. It was long believed that only a single widespread species existed, ''H. odoe'', but studies in 2011–2013 have shown that this species is restricted to parts of West and Central Africa. The well-known species of southern Africa, including Kafue River, is ''Hepsetus cuvieri''. These predatory fish reach up to in length. A 2024 study found their closest relatives to be the newly-defined family Lepidarchidae, which they diverged from during the Late Cretaceous. The divergence of these two families appears to have been driven by the Trans-Saharan Seaway, which served as a marine barrier between western and eastern Africa at the time. Species There are currently six recognized species in this genus: * ''Hepsetus cuvieri'' ( Castelnau, 1861) * ''Hepsetus kingsleyae'' Vreven, Decru & Snoeks, 2013 * ''Hepsetus ...

Characidae
Characidae, the characids, is a family of freshwater subtropical and tropical fish belonging to the order Characiformes. They are found throughout much of Central and South America, including such major waterways as the Amazon and Orinoco Rivers.Nelson (2006) These fish vary in length; many are less than . The name " characins" is a historical one, but scientists today tend to prefer "characids" to reflect their status as a, by and large, monophyletic group (at family rank). This family includes some of the first characiforms to be described to science, such as '' Charax'' and '' Tetragonopterus'', and thus lend their name to the order, as well as to common names such as "characin" and " tetra". Past taxonomic treatments had a much more expansive definition of the family, including numerous South American fish families such as the piranhas and dorados, as well as the African alestids. Following multiple taxonomic revisions, this was eventually restricted to just the Americ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Convergent Evolution
Convergent evolution is the independent evolution of similar features in species of different periods or epochs in time. Convergent evolution creates analogous structures that have similar form or function but were not present in the last common ancestor of those groups. The cladistic term for the same phenomenon is Cladogram#Homoplasies, homoplasy. The recurrent evolution of flight is a classic example, as flying pterygota, insects, birds, pterosaurs, and bats have independently evolved the useful capacity of flight. Functionally similar features that have arisen through convergent evolution are ''analogous'', whereas ''homology (biology), homologous'' structures or traits have a common origin but can have dissimilar functions. Bird, bat, and pterosaur wings are analogous structures, but their forelimbs are homologous, sharing an ancestral state despite serving different functions. The opposite of convergence is divergent evolution, where related species evolve different trai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archippus (poet)
Archippus (; Ancient Greek: Ἅρχιππος; fl. late 5th century BC) was an Athenian poet of the Old Comedy. His most famous play was the ''Fishes'', in which he satirized the fondness of the Athenian epicures for fish. The Alexandrian critics attributed to him the authorship of four plays previously assigned to Aristophanes (''Dionysus Shipwrecked'', ''Islands'', ''Niobos'', and ''Poetry''). Archippus was ridiculed by his contemporaries for his fondness for playing upon words.Schol. on Aristophanes, ''Wasps A wasp is any insect of the narrow-waisted suborder Apocrita of the order Hymenoptera which is neither a bee nor an ant; this excludes the broad-waisted sawflies (Symphyta), which look somewhat like wasps, but are in a separate suborder.

Esox
''Esox'' is a genus of freshwater fish commonly known as pike or pickerel. It is the type genus of the family (biology), family Esocidae. The type species of the genus is ''Esox lucius'', the northern pike. ''Esox'' have a fossil record extending back to the Paleocene. Modern large pike species are native to the Palearctic and Nearctic realms, ranging across Northern America and from Western Europe to Siberia in North Asia. Pike have the elongated, torpedo-like shape typical of predatory fishes, with sharply pointed heads and sharp teeth. Their coloration is typically grey-green with a mottled or spotted appearance with stripes along their backs, providing camouflage among underwater weeds, and each individual pike marking patterns are unique like fingerprints. Pikes can grow to a maximum recorded length of , reaching a maximum recorded weight of 67lb 8oz. Etymology The generic name ''Esox'' (pike fish) derives from the Greek language, Greek ἴσοξ (''ee-soks'', a large f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anchoa Hepsetus
''Anchoa hepsetus'', commonly known as the broad-striped anchovy, is a species of ray-finned fish in the family Engraulidae. It grows to be about 15 cm (6 in) long. The broad-striped anchovy is found in the west Atlantic along the North American coast from Nova Scotia and the Maine coast scarcely, and abundantly from the Chesapeake bay to the West Indies and Uruguay. It is found most commonly in shoals along coastal waters, as deep as 73 m (40 fathoms) although mostly found in water shallower than this. The broad-striped anchovy spawns in spring. Their eggs are pelagic and hatch within 48 hours at regular spring temperatures. At young ages, it eats copepods, but as the fish ages, its diet begins to consist of other small crustaceans, molluscs, and worm larvae. It is an important food staple for large commercial fishes, such as the American seatrout. It is commonly eaten by birds. It is elongate with large eyes and protuberant snout, large mouth and underslung jaw. Its ana ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
