Hypsigenyini
The hypsigenyine wrasses are saltwater fish of the tribe Hypsigenyini, a subgroup of the wrasse family (Wrasse, Labridae). The group is circumglobal, being found in almost all the of world's shallow tropical marine waters, although some species are also found in temperate zones. Taxonomy Hypsigenyini is the sister group to all other wrasse tribes. The group was first proposed in 1997. Since then, molecular phylogenetics has found that it also includes Odacidae, odacines and the genus ''Chiseltooth wrasse, Pseudodax''. Odacines were once considered to be their own taxonomic family, but have been found nested deep within the hypsigenyine wrasses, and are the sister group to the hypsigenyine genus ''Choerodon''. Odacines remain a Monophyly, monophyletic group however. ''Pseudodax'' was once considered to be the closest relative to parrotfish (tribe Scarini), but is now considered a basal hypsigenyine. Westneat & Alfaro (2005) and Hughes et al (2022) found that the hogfish (''Lach ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wrasse
The wrasses are a family, Labridae, of marine ray-finned fish, many of which are brightly colored. The family is large and diverse, with over 600 species in 81 genera, which are divided into nine subgroups or tribes. They are typically small, most of them less than long, although the largest, the humphead wrasse, can measure up to . They are efficient carnivores, feeding on a wide range of small invertebrates. Many smaller wrasses follow the feeding trails of larger fish, picking up invertebrates disturbed by their passing. Juveniles of some representatives of the genera ''Bodianus'', '' Epibulus'', '' Cirrhilabrus'', '' Oxycheilinus'', and '' Paracheilinus'' hide among the tentacles of the free-living mushroom corals and '' Heliofungia actiniformis''. Etymology The word "wrasse" comes from the Cornish word ''wragh'', a lenited form of ''gwragh'', meaning an old woman or hag, via Cornish dialect ''wrath''. It is related to the Welsh ''gwrach'' and Breton ''gwrac'h''. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Choerodon
''Choerodon'' is a genus of wrasses native to the Indian Ocean and the western Pacific Ocean. They originated in the Miocene, when the Australian and Eurasian Plates collided. They are commonly referred to as tuskfish, because most species have sharp tusk-like teeth. Taxonomy The genus ''Choerodon'' is most closely related to the odacine wrasses. Both groups are part of the wrasse tribe Hypsigenyini. ''Choerodon'' is split into 6 subgenera. Molecular phylogenetic analysis has so far demonstrated the monophyly of the subgenera, although not all species in the genus have been evaluated. '' Choerodon typus'' was traditionally placed within its own genus ''Xiphocheilus'', but both morphological and molecular analyses now place it within ''Choerodon'', with ''Xiphocheilus'' becoming its subgenus name instead. Potential tool use in tuskfishes Orange-dotted, blue, graphic, and blackspot tuskfish have been recorded using large rocks or hard coral as "anvils", upon which they sma ...

Bodianus
''Bodianus'' is a genus of fish in the family of wrasses, the Labridae, which are commonly known as hogfishes. They are found in the Atlantic, Indian and Pacific Ocean. These species have many parasites. Taxonomy ''Bodianus'' belongs to the wrasse tribe Hypsigenyini. Gomon (2006) split up the species in ''Bodianus'' amongst 10 subgenera. However, these sub-classifications of ''Bodianus'' only roughly line up with findings of more recent phylogenetic analyses. The three species '' B. darwini'', '' B. pulcher'', and '' B. reticulatus'', commonly called the sheephead wrasses, have traditionally formed their own genus ''Semicossyphus''. Although at least the latter two species form a monophyletic lineage with each other, ''Semicossyphus'' has subsequently been synonymized with ''Bodianus'', as molecular phylogenetics found that ''Semicossyphus'' is nested deep within ''Bodianus''. Similarly, '' Clepticus parrae'' and likely all '' Clepticus'' species also nest within ''Bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Early Eocene
In the geologic timescale the Ypresian is the oldest age (geology), age or lowest stage (stratigraphy), stratigraphic stage of the Eocene. It spans the time between , is preceded by the Thanetian Age (part of the Paleocene) and is followed by the Eocene Lutetian Age. The Ypresian is consistent with the Lower Eocene (Early Eocene). Events The Ypresian Age begins during the throes of the Paleocene–Eocene Thermal Maximum (PETM). The Fur Formation in Denmark, the Messel shales in Germany, the Oise amber of France and Cambay amber of India are of this age. The Eocene Okanagan Highlands are an uplands subtropical to temperate series of lakes from the Ypresian. The Ypresian is additionally marked by another warming event called the Early Eocene Climatic Optimum (EECO). The EECO is the longest sustained warming event in the Cenozoic record, lasting about 2–3 million years between 53 and 50 Ma. The interval is characterized by low oxygen-18 isotopes, high levels of atmospheric pCO2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miocene
The Miocene ( ) is the first epoch (geology), geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene followed the Oligocene and preceded the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by distinct global events but by regionally defined transitions from the warmer Oligocene to the cooler Pliocene Epoch. During the Early Miocene, Afro-Arabia collided with Eurasia, severing the connection between the Mediterranean and Indian Oceans, and allowing the interchange of fauna between Eurasia and Africa, including the dispersal of proboscideans and Ape, hominoids into Eurasia. During the late Miocene, the conn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pieter Bleeker
Pieter Bleeker (10 July 1819 – 24 January 1878) was a Dutch medical doctor, Ichthyology, ichthyologist, and Herpetology, herpetologist. He was famous for the ''Atlas Ichthyologique des Indes Orientales Néêrlandaises'', his monumental work on the fishes of East Asia published between 1862 and 1877. Life and work Bleeker was born on 10 July 1819 in Zaandam. He was employed as a medical officer in the Royal Netherlands East Indies Army from 1842 to 1860, (in French). stationed in the Dutch East Indies (now Indonesia). During that time, he did most of his ichthyology work, besides his duties in the army. He acquired many of his specimens from local fishermen, but he also built up an extended network of contacts who would send him specimens from various government outposts throughout the islands. During his time in Indonesia, he collected well over 12,000 specimens, many of which currently reside at the Naturalis Biodiversity Center in Leiden. Bleeker corresponded with Auguste Dum� ...

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 ...

He was the only son of Harcourt George Barnard, a solicitor from Lambeth, and Anne Elizabeth Porter of Royston. Life and career Barnard was born in London. His first education was at a private school in Camberley from where he went to the Realgymnasium in Mannheim to improve his German.
