Facelina Quatrefagesi
''Caloria quatrefagesi'' is a species of sea slug, an aeolid nudibranch, a marine gastropod mollusc in the family Facelinidae. Taxonomy ''Caloria elegans'' is morphologically very similar to ''Facelina quatrefagesi''. ''Facelina quatrefagesi'' was considered as a synonym of ''Caloria elegans'', but a combination of DNA evidence and morphological comparison resulted in them being recognised as separate valid species.Furfaro G., Mariottini P., Modica M. V., Trainito E., Doneddu M. & Oliverio M. (2016). "Sympatric sibling species: the case of ''Caloria elegans'' and ''Facelina quatrefagesi'' (Gastropoda: Nudibranchia)". ''Scientia Marina'' 80(4): 511-520. . The species was transferred to the genus ''Caloria'' in 2021.

Albert Jean Baptiste Marie Vayssière
Albert Jean Baptiste Marie Vayssière (8 July 1854, Avignon – 13 January 1942, Marseille) was a French scientist, a biologist, specifically a malacologist and entomologist, i.e. someone who studies mollusks, and insects. Within the Mollusca, Vayssière specialized in sea slugs and bubble snails, i.e. marine opisthobranch gastropods. He made significant contributions towards a better understanding of the general biology, phylogenetic relationships, biogeography and ecological distribution of the group.Scientific Exploration in the Mediterranean Region Biodiversity of the Mediterranean Opisthobranc ...

Species
In biology, a species is the basic unit of 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 produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, 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 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 specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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—sensory te ...

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. Distribut ...

Marine (ocean)
The ocean (also the sea or the world ocean) is the body of salt water that covers approximately 70.8% of the surface of Earth and contains 97% of Earth's water. An ocean can also refer to any of the large bodies of water into which the world ocean is conventionally divided."Ocean." ''Merriam-Webster.com Dictionary'', Merriam-Webster, |
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.

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.

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 opini ...

Villefranche-sur-Mer
Villefranche-sur-Mer (, ; oc, Vilafranca de Mar ; it, Villafranca Marittima ) is a resort town in the Alpes-Maritimes department in the Provence-Alpes-Côte d'Azur region on the French Riviera and is located south-west of the Principality of Monaco, which is just west of the French-Italian border. Geography Villefranche-sur-Mer is immediately to the east of the city of Nice, along Mont Boron, Mont Alban and Mont Vinaigrier, and south-west of Monaco. The bay (''rade'') of Villefranche is one of the deepest natural harbours of any port in the Mediterranean Sea and provides safe anchorage for large ships from easterly winds. Reaching depths of 320 ft (95 m) between the Cape of Nice and Cap Ferrat; it extends to the south to form a 1,700 ft (500 m) abyss known as the undersea Canyon of Villefranche at about one nautical mile off the coastline. The Bay is the place where the American 6th Fleet moors when cruising the Mediterranean Coast. The city limits ext ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
