Tenellia
''Tenellia'' is a genus of sea slugs, aeolid nudibranchs, marine gastropod mollusks in the family Trinchesiidae.Gofas, S. (2004)''Tenellia'' A. Costa, 1866.In: MolluscaBase (2016). Accessed through: World Register of Marine Species on 2016-12-23. Taxonomic history This was a small genus until a DNA phylogeny of the former family Tergipedidae resulted in most species of '' Cuthona'' being transferred to this genus.Cella, K; Carmona Barnosi, L.; Ekimova, I; Chichvarkhin, A; Schepetov, D; Gosliner, T. M. (2016)''A radical solution: The phylogeny of the nudibranch family Fionidae.''PLoS ONE. 11(12): e0167800. Miller (2004) restricted the genus ''Cuthona'' Alder & Hancock, 1855 to the type species, ''C. nana'' (Alder & Hancock, 1842), and transferred to the genus ''Trinchesia'' the rest of the species previously included in ''Cuthona''. Miller has been followed by some authors, and has not been followed by others - and there is currently much instability on the extension and conten ...

Huelva
Huelva (, ) is a city in southwestern Spain, the capital of the province of Huelva in the autonomous community of Andalusia. It is between two short rias though has an outlying spur including nature reserve on the Gulf of Cádiz coast. The rias are of the Odiel and Tinto rivers and are good natural harbors. According to the 2010 census, the city had a population of 149,410. Huelva is home to Recreativo de Huelva, the oldest football club in Spain. While the existence of a pre-Phoenician settlement within the current urban limits since circa 1250 BC has been tentatively defended by scholars, Phoenicians established a stable colony roughly by the 9th century BC. History Protohistory At least up to the 1980s and 1990s, the mainstream view was that Huelva at first was an autochthonous Tartessian settlement (even the very same Tartessos mentioned in Greek sources) yet some later views tended to rather stress a pluri-ethnic enclave mixing natives with peoples with a mainly Ph ...

El Portil
El Portil and Nuevo Portil are two coastal population units separated by one street, known as ''Laguna Seca street'', and managed by two municipalities, in the Province of Huelva, autonomous community of Andalusia, in southern Spain. People differentiates on which side of the street they are using ''El Portil'' or ''Nuevo Portil'' as if it were the name of districts of the same town. ''El Portil'' is managed by the municipality of Punta Umbría whereas ''Nuevo Portil'' is managed by the Cartaya municipality. The stable population, in winter, is about 2400 inhabitants about (1122 in Nuevo Portil and 1027 in El Portil) in 2016, while in the Summer season, is around 28.000. Most of them, tourists from the provinces of Huelva, Seville, Badajoz, Madrid and even the Basque Country and Galicia. People from other countries prefer to visit El Portil and Nuevo Portil in Autumn, Winter and Spring seasons. Located parallel to the end zone of the Flecha de El Rompido, the main economic acti ...

Family (biology)
Family ( la, familia, plural ') 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". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opi ...

Mollusc
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species.

Gastropod
The gastropods (), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, from freshwater, and from land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs. The class Gastropoda contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Late Cambrian. , 721 families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently extant with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mollusca, and are the most highly diversified class in the phylum, with 65,000 to 80,000 living snail and slug species.

Nudibranch
Nudibranchs () are a group of soft-bodied marine gastropod molluscs which shed their shells after their larval stage. They are noted for their often extraordinary colours and striking forms, and they have been given colourful nicknames to match, such as "clown", "marigold", "splendid", "dancer", "dragon", or "sea rabbit". Currently, about 3,000 valid species of nudibranchs are known.Ocean Portal (2017)A Collage of Nudibranch Colors Smithsonian National Museum of Natural History. Retrieved 17 April 2018. The word "nudibranch" comes from the Latin "naked" and the Ancient Greek () " gills". Nudibranchs are often casually called sea slugs, as they are a family of opistobranchs (sea slugs), within the phylum Mollusca (molluscs), but many sea slugs belong to several taxonomic groups which are not closely related to nudibranchs. A number of these other sea slugs, such as the photosynthetic '' Sacoglossa'' and the colourful Aglajidae, are often confused with nudibranchs. Dist ...

Sea Slug
Sea slug is a common name for some marine invertebrates with varying levels of resemblance to terrestrial slugs. Most creatures known as sea slugs are gastropods, i.e. they are sea snails (marine gastropod mollusks) that over evolutionary time have either completely lost their shells, or have seemingly lost their shells due to having a greatly reduced or internal shell. The name "sea slug" is most often applied to nudibranchs, as well as to a paraphyletic set of other marine gastropods without obvious shells. Sea slugs have an enormous variation in body shape, color, and size. Most are partially translucent. The often bright colors of reef-dwelling species implies that these animals are under constant threat of predators, but the color can serve as a warning to other animals of the sea slug's toxic stinging cells ( nematocysts) or offensive taste. Like all gastropods, they have small, razor-sharp teeth, called radulas. Most sea slugs have a pair of rhinophores—sens ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour or ecological niche. In addition, paleontologists 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. However, only about 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fionidae
Fionidae is a family of sea slugs, aeolid nudibranchs, marine gastropod molluscs in the superfamily Fionoidea. Taxonomic history This family was expanded to include Tergipedidae, Eubranchidae and Calmidae as a result of a molecular phylogenetics study. This was reversed in 2017 with further DNA evidence and a re-interpretation of genus and family characteristics.Korshunova, T.; Martynov, A.; Picton, B.
