Cleaner 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''. Taxon ... [...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] |
Cirrhilabrus
''Cirrhilabrus'', the fairy wrasses, is a genus of fish in the family (biology), family Labridae native to coral reefs and nearby habitats in the Indo-Pacific region. They are brightly colored and do not surpass in length. Males are larger and more colorful than females. They are commonly kept in aquarium, aquaria. Species There are currently more than 60 recognized species in this genus: * ''Cirrhilabrus adornatus'' John Ernest Randall, J. E.

Odacidae
The Odacidae are a small Family (biology), family of ray-finned fishes commonly known as cales and weed whitings, formerly classified within the Order (biology), order Perciformes. They are related to the much larger families of the wrasses and parrotfish. More recent workers have classified this family within the order Labriformes, alongside the wrasses and parrotfishes, within the clade Percomorpha. Odacids are found in coastal waters off Southern Australia and New Zealand. They include species that feed on small invertebrates, as well as herbivorous grazers, some of which are able to feed on chemically unpleasant varieties of kelp otherwise unpalatable to fish. Genera The following genera are classified in the family Odacidae: *''Haletta'' Gilbert Percy Whitley, Whitley, 1947 *''Heteroscarus'' Francis de Laporte de Castelnau, Castelnau, 1872 *''Neoodax'' Castelnau, 1875 *''Odax'' Achille Valenciennes, Valenciennes, 1840 *''Parodax'' John K.

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 ...

Parrotfish
Parrotfish (named for their mouths, which resemble a parrot's beak) are a clade of fish placed in the tribe Scarini of the wrasse family (Labridae). Traditionally treated as their own family (Scaridae), genetic studies have found them to be deeply nested within the wrasses, and they are now treated as a subfamily (Scarinae) or tribe (Scarini) of them. With roughly 95 species, this group's largest species richness is in the Indo-Pacific. They are found in coral reefs, rocky coasts, and seagrass beds, and can play a significant role in bioerosion. Taxonomy Traditionally, the parrotfishes have been considered to be a family level taxon, Scaridae. Although phylogenetic and evolutionary analyses of parrotfishes are ongoing, they are now accepted to be a clade in the wrasses closely related to the tribe Cheilini, and are now commonly referred to as scarine labrids (tribe Scarini, family Labridae). Some authorities have preferred to maintain the parrotfishes as a family-level taxon, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breton Language
Breton (, , ; or in Morbihan) is a Southwestern Brittonic language of the Celtic languages, Celtic language group spoken in Brittany, part of modern-day France. It is the only Celtic language still widely in use on the European mainland, albeit as a member of the Insular Celtic languages, insular branch instead of the extinct Continental Celtic languages, continental grouping. Breton was brought from Great Britain to Armorica (the ancient name for the coastal region that includes the Brittany peninsula) by migrating Britons (Celtic people), Britons during the Early Middle Ages, making it an Insular Celtic language. Breton is most closely related to Cornish language, Cornish, another Southwestern Brittonic language. Welsh language, Welsh and the extinct Cumbric language, Cumbric, both Western Brittonic languages, are more distantly related, and the Goidelic languages (Irish language, Irish, Manx language, Manx, Scottish Gaelic) have a slight connection due to both of their origi ...

Welsh Language
Welsh ( or ) is a Celtic languages, Celtic language of the Brittonic languages, Brittonic subgroup that is native to the Welsh people. Welsh is spoken natively in Wales by about 18% of the population, by some in England, and in (the Welsh colony in Chubut Province, Argentina). It is spoken by smaller numbers of people in Canada and the United States descended from Welsh immigrants, within their households (especially in Nova Scotia). Historically, it has also been known in English as "British", "Cambrian", "Cambric" and "Cymric". The Welsh Language (Wales) Measure 2011 gave the Welsh language official status in Wales. Welsh and English are ''de jure'' official languages of the Senedd (the Welsh parliament), with Welsh being the only ''de jure'' official language in any part of the United Kingdom, with English being merely ''de facto'' official. According to the 2021 United Kingdom census, 2021 census, the Welsh-speaking population of Wales aged three or older was 538,300 ( ...

Cornish Dialect
The Cornish dialect (also known as Cornish English, Anglo-Cornish or Cornu-English) is a dialect of English spoken in Cornwall by Cornish people. Dialectal English spoken in Cornwall is to some extent influenced by Cornish grammar, and often includes words derived from the Cornish language. The Cornish language is a Celtic language of the Brythonic branch, as are the Welsh and Breton languages. In addition to the distinctive words and grammar, there are a variety of accents found within Cornwall from the north coast to that of the south coast and from east to west Cornwall. Typically, the accent is more divergent from Standard British English the further west through Cornwall one travels. The speech of the various parishes being to some extent different from the others was described by John T. Tregellas and Thomas Quiller Couch towards the end of the 19th century. Tregellas wrote of the differences as he understood them and Couch suggested the parliamentary constituency boun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lenition
In linguistics, lenition is a sound change that alters consonants, making them "weaker" in some way. The word ''lenition'' itself means "softening" or "weakening" (from Latin 'weak'). Lenition can happen both synchronically (within a language at a particular point in time) and diachronically (as a language changes over time). Lenition can involve such changes as voicing a voiceless consonant, causing a consonant to relax occlusion, to lose its place of articulation (a phenomenon called '' debuccalization'', which turns a consonant into a glottal consonant like or ), or even causing a consonant to disappear entirely. An example of synchronic lenition is found in most varieties of American English, in the form of tapping: the of a word like ''wait'' is pronounced as the more sonorous in the related form ''waiting'' . Some varieties of Spanish show debuccalization of to at the end of a syllable, so that a word like "we are" is pronounced . An example of diachronic l ...

Cornish Language
Cornish (Standard Written Form: or , ) is a Southwestern Brittonic language, Southwestern Brittonic language of the Celtic language family. Along with Welsh language, Welsh and Breton language, Breton, Cornish descends from Common Brittonic, a language once spoken widely across Great Britain. For much of the Middle Ages, medieval period Cornish was the main language of Cornwall, until it was gradually pushed westwards by the spread of English language, English. Cornish remained a vernacular, common community language in parts of Cornwall until the mid-18th century, and there is some evidence for traditional speakers persisting into the 19th century. Cornish became extinct language, extinct as a living community language in Cornwall by the last speaker of the Cornish language, end of the 18th century, although knowledge of Cornish, including speaking ability to a certain extent, persisted within some families and individuals. Cornish language revival, A revival started in the e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heliofungia Actiniformis
''Heliofungia actiniformis'' is a solitary species of mushroom coral, a large polyp stony coral in the family Fungiidae. This coral is found in shallow water in the Indo-Pacific region. It is a zooxanthellate species. It is a popular coral in the reef aquarium trade; wild populations are threatened by disease, climate change, and over-collecting, and the species is considered vulnerable by the IUCN. Description Although fixed to the substrate as a juvenile, this coral becomes detached later and is free-living as an adult. It is circular or oval with a diameter of up to and height of . The corallum (stony skeleton) is thick and solid. The septa (stony ridges) are in several orders. The early order septa are larger than later order ones and have more prominent, lobe-like or triangular teeth. All the septa are granulate, and continue to the underside of the corallum as fine ridges known as costae. There is an attachment scar in the centre of the underside. The polyp is thick and ...
