Trapania Hispalensis
''Trapania hispalensis'' is a species of sea slug, a Doridoidea, dorid nudibranch, a marine (ocean), marine gastropod mollusc in the family (biology), family Goniodorididae. Distribution This species was first described from the Straits of Gibraltar. It is found from Ceuta, North Africa to Faro, Portugal. Description This goniodorid nudibranch is translucent white in colour, with yellow markings. The rhinophores, gills and processes are covered with yellow pigment and there is a patch of yellow on the tail. It is very similar in colour to ''Trapania tartanella'' except that it has yellow markings with no tendency to become orange at the tips of the papillae, gills and rhinophores.Rudman, W.B., 2005 (September 8''Trapania hispalensis'' Cervera & Garcia-Gomez, 1989.[In] Sea Slug Forum.

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] |
Straits Of Gibraltar
The Strait of Gibraltar ( ar, مضيق جبل طارق, Maḍīq Jabal Ṭāriq; es, Estrecho de Gibraltar, Archaic: Pillars of Hercules), also known as the Straits of Gibraltar, is a narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa. The two continents are separated by of ocean at the Strait's narrowest point between Point Marroquí in Spain and Point Cires in Morocco. Ferries cross between the two continents every day in as little as 35 minutes. The Strait's depth ranges between which possibly interacted with the lower mean sea level of the last major glaciation 20,000 years ago when the level of the sea is believed to have been lower by . The strait lies in the territorial waters of Morocco, Spain, and the British overseas territory of Gibraltar. Under the United Nations Convention on the Law of the Sea, foreign vessels and aircraft have the freedom of navigation and overflight ...

Entoprocta
Entoprocta (), or Kamptozoa , is a phylum of mostly sessile aquatic animals, ranging from long. Mature individuals are goblet-shaped, on relatively long stalks. They have a "crown" of solid tentacles whose cilia generate water currents that draw food particles towards the mouth, and both the mouth and anus lie inside the "crown". The superficially similar Bryozoa (Ectoprocta) have the anus outside a "crown" of hollow tentacles. Most families of entoprocts are colonial, and all but 2 of the 150 species are marine. A few solitary species can move slowly. Some species eject unfertilized ova into the water, while others keep their ova in brood chambers until they hatch, and some of these species use placenta-like organs to nourish the developing eggs. After hatching, the larvae swim for a short time and then settle on a surface. There they metamorphose, and the larval gut rotates by up to 180°, so that the mouth and anus face upwards. Both colonial and solitary species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trapania Tartanella
''Trapania tartanella'' is a species of sea slug, a dorid nudibranch, a marine gastropod mollusc in the family Goniodorididae. Distribution This species was first described from the Mediterranean. It is found on the Atlantic coast from Portugal to Pembrokeshire in South Wales. Description This goniodorid nudibranch is translucent white in colour, with yellow-orange markings. The rhinophores, gills and processes are tipped with yellow pigment which becomes orange at the extremities.

Faro, Portugal
Faro ( , ) is a municipality, the southernmost city and capital of the district of the same name, in the Algarve region of southern Portugal. With an estimated population of 60,995 inhabitants in 2019 (with 39,733 inhabitants in the city proper, making it the biggest city and second most populous municipality in the Algarve (after Loulé) and one of the biggest in Southern Portugal), the municipality covers an area of about . History The Ria Formosa lagoon attracted humans from the Palaeolithic age until the end of prehistory. The first settlements date from the fourth century BC, during the period of Phoenician colonization of the western Mediterranean. At the time, the area was known as Ossonoba, and was the most important urban centre of southern Portugal and commercial port for agricultural products, fish, and minerals. Between the second and eighth centuries, the city was under the domain of the Romans, then the Byzantines, and later Visigoths, before being conquere ...

Ceuta
Ceuta (, , ; ar, سَبْتَة, Sabtah) is a Spanish autonomous city on the north coast of Africa. Bordered by Morocco, it lies along the boundary between the Mediterranean Sea and the Atlantic Ocean. It is one of several Spanish territories in Africa and, along with Melilla and the Canary Islands, one of only a few that are permanently inhabited by a civilian population. It was a regular municipality belonging to the province of Cádiz prior to the passing of its Statute of Autonomy in March 1995, henceforth becoming an autonomous city. Ceuta, like Melilla and the Canary Islands, was classified as a free port before Spain joined the European Union. Its population consists mainly of Christians and Muslims. There is also a small minority of Sephardic Jews and Sindhi Hindus, the latter of whom originate from current-day Pakistan. Spanish is the only official language, but Darija Arabic is quite prominent as well. Names The name Abyla has been said to have been a ...

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] |
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.
