Eunicella Albicans
The whip fan (''Eunicella albicans''), also called the flagellar sea fan, is a species of gorgonian sea fan in the family Eunicellidae.McFadden, C.S.; Cordeiro, R.; Williams, G.; van Ofwegen, L.

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Endemism
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Whip Fan Nudibranch
''Duvaucelia odhneri'', is a species of Dendronotida, dendronotid nudibranch. It is a marine (ocean), marine gastropod mollusc in the family (biology), family Tritoniidae. The specific name ''odhneri'' is in honour of Swedish malacologist Nils Hjalmar Odhner. This species was originally described as ''Duvaucelia odhneri'' but this became a homonym of ''Tritonia odhneri'' Marcus, 1959 when the genus ''Duvaucelia'' was moved within ''Tritonia'' in 1983. In 2020 the genus ''Duvaucelia'' was brought back into use and the name reverted to the original combination of Tardy, 1963.Korshunova, T.; Martynov, A. (2020)Consolidated data on the phylogeny and evolution of the family Tritoniidae (Gastropoda: Nudibranchia) contribute to genera reassessment and clarify the taxonomic status of the neuroscience models ''Tritonia'' and ''Tochuina''.PLOS ONE. 15(11): e0242103. Distribution This species is found in the north Atlantic Ocean off the United Kingdom, Ireland and France. It is also reporte ...

Gorgoniidae
Gorgoniidae is a family of soft corals, a member of the subclass Octocorallia in the phylum Cnidaria. Nearly all the genera and species are native to the east and west coasts of America. Characteristics Originally the members of the family Gorgoniidae included a much wider range of genera than it does now and was used for all of the horny Octocorallia. Now it is restricted to those species where the "calcareous spicules are less than 0.3 mm. in length, sculptured with regularly disposed girdles of complicated tubercles ('warts'), the anthocodiae are relatively unarmed, at most with but a few characteristically shaped flat rods en chevron beneath each tentacle, the horny axial cylinder is weakly loculated if at all, and is perforated by a relatively narrow, chambered central chord, and in which the branchlets are usually quite slender, with a thin cortex." The polyps are retractable and the stems have an axis of the protein gorgonin surrounding a narrow, hollow, cross-cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
