Atagema Rugosa
''Atagema rugosa'', the rugby-ball dorid, is a species of dorid nudibranch, a marine gastropod mollusc in the family Discodorididae. Distribution This species was described from Cap l'Abeille, near Banyuls-sur-Mer, France. It has been reported from the bay of Gallipoli, Italy, in the Mediterranean Sea and around the southern African Southern Africa is the southernmost subregion of the African continent, south of the Congo and Tanzania. The physical location is the large part of Africa to the south of the extensive Congo River basin. Southern Africa is home to a numbe ... coast on the Atlantic side of the Cape Peninsula in 10–15 m of water. It is probable that the species known by this name in South Africa is actually a distinct species. Description ''Atagema rugosa'' is described as a beige animal, darker in the lower parts of the mantle. Its tubercles are arranged in crests forming a network. It has five gills, with the three posterior held almost horizontal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alice Pruvot-Fol
Alice Pruvot-Fol (4 August 1873 – 28 March 1972) was a French opisthobranch malacologist. She was the author of many new species, mostly described on the basis of preserved animals. She described a new species (''Nembrotha rutilans'', Pruvot-Fol, 1931) on the basis of a painted illustration in a book by William Saville-Kent (1893) entitled ''The Great Barrier Reef of Australia''. She continued working and naming new species until late in her life. Even in 1962, when she was 89 years old, she named ''Phyllidia pulitzeri''.

Gallipoli
The Gallipoli peninsula (; tr, Gelibolu Yarımadası; grc, Χερσόνησος της Καλλίπολης, ) is located in the southern part of East Thrace, the European part of Turkey, with the Aegean Sea to the west and the Dardanelles strait to the east. Gallipoli is the Italian form of the Greek name (), meaning 'beautiful city', the original name of the modern town of Gelibolu. In antiquity, the peninsula was known as the Thracian Chersonese ( grc, Θρακικὴ Χερσόνησος, ; la, Chersonesus Thracica). The peninsula runs in a south-westerly direction into the Aegean Sea, between the Dardanelles (formerly known as the Hellespont), and the Gulf of Saros (formerly the bay of Melas). In antiquity, it was protected by the Long Wall, a defensive structure built across the narrowest part of the peninsula near the ancient city of Agora. The isthmus traversed by the wall was only 36 stadia in breadthHerodotus, ''The Histories''vi. 36 Xenophon, ibid.; Pseudo ...

Sponge
Sponges, the members of the phylum Porifera (; meaning 'pore bearer'), are a basal animal clade as a sister of the diploblasts. They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them, consisting of jelly-like mesohyl sandwiched between two thin layers of cells. Sponges have unspecialized cells that can transform into other types and that often migrate between the main cell layers and the mesohyl in the process. Sponges do not have nervous, digestive or circulatory systems. Instead, most rely on maintaining a constant water flow through their bodies to obtain food and oxygen and to remove wastes. Sponges were first to branch off the evolutionary tree from the last common ancestor of all animals, making them the sister group of all other animals. Etymology The term ''sponge'' derives from the Ancient Greek word ( 'sponge'). Overview Sponges are similar to other animals in that they are multicellular, he ...

Perfoliate
The following is a list of terms which are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (a single leaf blade or lamina) or compound (with several leaflets). The edge of the leaf may be regular or irregular, may be smooth or bearing hair, bristles or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf article. The terms listed here all are supported by technical and professional usage, but they cannot be represented as mandatory or undebatable; readers must use their judgement. Authors often use terms arbitrarily, or coin them to taste, possibly in ignorance of established terms, and it is not always clear whether because of ignorance, or personal preference, or because usages change with time or context, or because of variation between specimens, even specimens from the same plant. For example, whether to call leaves on the same tree "acuminate", "lanceolate", or "linear" could ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhinophore
A rhinophore is one of a pair of chemosensory club-shaped, rod-shaped or ear-like structures which are the most prominent part of the external head anatomy in sea slugs, marine gastropod opisthobranch mollusks such as the nudibranchs, sea hares (Aplysiomorpha), and sap-sucking sea slugs (Sacoglossa). Etymology The name relates to the rhinophore's function as an organ of "smell". ''Rhino-'' means nose from Ancient Greek ῥίς ''rhis'' and from its genitive ῥινός ''rhinos''. "Phore" means "to bear" from New Latin ''-phorus'' and from Greek -phoros (φορος) "bearing", a derivative of ''phérein'' (φέρειν). Function Rhinophores are scent or taste receptors, also known as chemosensory organs situated on the dorsal surface of the head. They are primarily used for distance chemoreception and rheoreception (response to water current). The "scents" detected by rhinophores are chemicals dissolved in the sea water. The fine structure and hairs of the rhinophor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gill
A gill () is a respiratory organ that many aquatic organisms use to extract dissolved oxygen from water and to excrete carbon dioxide. The gills of some species, such as hermit crabs, have adapted to allow respiration on land provided they are kept moist. The microscopic structure of a gill presents a large surface area to the external environment. Branchia (pl. branchiae) is the zoologists' name for gills (from Ancient Greek ). With the exception of some aquatic insects, the filaments and lamellae (folds) contain blood or coelomic fluid, from which gases are exchanged through the thin walls. The blood carries oxygen to other parts of the body. Carbon dioxide passes from the blood through the thin gill tissue into the water. Gills or gill-like organs, located in different parts of the body, are found in various groups of aquatic animals, including mollusks, crustaceans, insects, fish, and amphibians. Semiterrestrial marine animals such as crabs and mudskippers have gill cham ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cape Peninsula
The Cape Peninsula ( af, Kaapse Skiereiland) is a generally mountainous peninsula that juts out into the Atlantic Ocean at the south-western extremity of the African continent. At the southern end of the peninsula are Cape Point and the Cape of Good Hope. On the northern end is Table Mountain, overlooking Table Bay and the city bowl of Cape Town, South Africa. The peninsula is 52 km long from Mouille point in the north to Cape Point in the south. The Peninsula has been an island on and off for the past 5 million years, as sea levels fell and rose with the Glacial period, ice age and interglacial global warming cycles of, particularly, the Pleistocene. The last time that the Peninsula was an island was about 1.5 million years ago. Soon afterwards it was joined to the mainland by the Geology of Cape Town#Tertiary to Recent events, emergence from the sea of the sandy area now known as the Cape Flats. The towns and villages of the Cape Peninsula and Cape Flats, and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Banyuls-sur-Mer
Banyuls-sur-Mer (; ) is a commune in the Pyrénées-Orientales department in southern France. It was first settled by Greeks starting in 400 BCE. Geography Location Banyuls-sur-Mer is located in the canton of La Côte Vermeille and in the arrondissement of Céret. Banyuls-sur-Mer is neighbored by Cerbère, Port-Vendres, Argelès-sur-Mer and Collioure on its French borders, and by Espolla, Rabós, Colera and Portbou on its Spanish borders. The foothills of Pyrenees, the ''Monts Albères'', run into the Mediterranean Sea in Banyuls-sur-Mer, creating a steep cliff line. Toponymy Banyuls-sur-Mer was first mentioned in 981 as ''Balneum'' or ''Balneola''. In 1074, the town started being called ''Bannils de Maritimo'' in order to distinguish it from Banyuls-dels-Aspres, which lies away. In 1197, the town was mentioned as ''Banullis de Maredine'' and in 1674. In Catalan, it has been called ''Banyuls de la Marenda'' since the 19th century. The name Banyuls indicates the presence ...

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] |
Discodorididae
Discodorididae is a taxonomic family of sea slugs, specifically dorid nudibranchs, marine gastropod mollusks in the superfamily Doridoidea.Bouchet, P. (2011). Discodorididae. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=1761 on 2011-08-23 Species in this family belong to the cryptobranch dorid nudibranchs, i.e. they are able to retract their gills into a gill pocket (cryptobranch = hidden gills). Most are small and hard to identify. Most are thought to feed at night on sponges, while during the day they search for dark areas or remain hidden under rocks. One example of a discodoridid is the "Pacific sea lemon" or "speckled sea lemon", ''Peltodoris nobilis'', which occurs off the coast of British Columbia to Baja California from low-tide waters to a depth of about 200 m. Not only is this species yellow with a bumpy surface, but it also gives off a strong fruity citrus smell when handled, adding to its resemblance ...
