Antiopella Cristata
''Antiopella cristata'', sometimes known by the common name crested aeolis, is a species of nudibranch, a marine gastropod mollusc in the family Janolidae. Taxonomy Previously some authors synonymised ''Antiopella'' with ''Janolus'' and assigned the genus ''Janolus'' to the Janolidae family (see ITIS.gov or AnimalDiversity), others (see Seaslug Forum) to the family of Zephyrinidae, and these were synonymised names of Proctonotidae (see WoRMS). In 2019 an integrated taxonomic study reinstated ''Antiopella'' and ''Janolus'' as separate genera and placed them in the family Janolidae. Description This species is semi-transparent and has an oval-shaped outline. It is cream or light brown in colour, and grows to approximately 7.5 cm in length. The head has oral tentacles that are short. The lateral cerata are numerous, have a smooth surface and an inflated appearance. The central digestive gland lobe is thin and brown in colour and can be seen through each ceras. These gland l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bryozoa
Bryozoa (also known as the Polyzoa, Ectoprocta or commonly as moss animals) are a phylum of simple, aquatic invertebrate animals, nearly all living in sedentary colonies. Typically about long, they have a special feeding structure called a lophophore, a "crown" of tentacles used for filter feeding. Most marine bryozoans live in tropical waters, but a few are found in oceanic trenches and polar waters. The bryozoans are classified as the marine bryozoans (Stenolaemata), freshwater bryozoans (Phylactolaemata), and mostly-marine bryozoans (Gymnolaemata), a few members of which prefer brackish water. 5,869living species are known. At least two genera are solitary (''Aethozooides'' and ''Monobryozoon''); the rest are colonial. The terms Polyzoa and Bryozoa were introduced in 1830 and 1831, respectively. Soon after it was named, another group of animals was discovered whose filtering mechanism looked similar, so it was included in Bryozoa until 1869, when the two groups were no ...

Molluscs Of The Mediterranean Sea
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. The gastropods ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''Reteporella grimaldii'' is a species of bryozoans in the family Phidoloporidae Phidoloporidae is a family within the bryozoan order Cheilostomatida.

Levanto, Liguria
Levanto (; lij, Lévanto or , locally ) is a (municipality) in the province of La Spezia in the Italian region of Liguria, located almost southeast of Genoa and about northwest of La Spezia. The town is on the coast at the mouth of a river valley, between hills thickly wooded with olive and pine trees. The ridges on either side of the valley thrust out into the sea as the headlands of Mesco and Levanto. The municipality forms part of the coastal district known as the Comunità Montana della Riviera Spezzina, and part of its territory is included in the Cinque Terre National Park. History In Roman times there was already a small settlement there by the name of Ceula, an important nodal point due to its location and harbour. At the beginning of the 9th century, the bell tower of the present church, the Chiesa di San Siro, served as a watchtower and as a defence against dangers from the sea. From the 13th century, however, the importance of the area began to decline – t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ligurian Sea
The Ligurian Sea ( it, Mar Ligure; french: Mer Ligurienne; lij, Mâ Ligure) is an arm of the Mediterranean Sea. It lies between the Italian Riviera (Liguria) and the island of Corsica. The sea is thought to have been named after the ancient Ligures people. Geography The sea borders Italy as far as its border with France, and the French island of Corsica. In the east, the sea borders the Tyrrhenian Sea, while in the west it borders the Mediterranean Sea proper. Genoa is the most prominent city in the area. The northwest coast is noted for its scenic beauty and favourable climate. The Gulf of Genoa is its northernmost part. The sea receives the Arno River from the east and many other rivers that originate in the Apennines. The ports of Genoa, La Spezia, and Livorno are on its rocky coast. It reaches a maximum depth of more than northwest of Corsica. According to a 1983 study, since 1977 a series of experimental analyses on sea-level variations at Genoa and Imperia highlight ...

Bugula Neritina
''Bugula neritina'' ( commonly known as brown bryozoan or common bugula) is a cryptic species complex of sessile marine animal in the genus ''Bugula''.Gordon, D. (2015). Bugula neritina (Linnaeus, 1758). In: Bock, P.; Gordon, D. (2015) World List of Bryozoa. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=111158 on 2015-09-02 It is invasive with a cosmopolitan distribution. ''Bugula neritina'' is of interest from a drug discovery perspective because its bacterial symbiont, ''Candidatus'' Endobugula sertula, produces the bryostatins, a group of around twenty bioactive natural products. The bryostatins are under investigation for their therapeutic potential directed at cancer immunotherapy, treatment of Alzheimer's disease, and HIV/AIDS eradication, due to their low toxicity and antineoplastic activity. The draft whole genome of ''Bugula neritina'' has recently been sequenced. This adds to the growing number of geno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bugula Plumosa
''Crisularia plumosa'' is a species of bryozoan belonging to the family Bugulidae, commonly known as the feather bryozoan. It is native to the Atlantic Ocean. Description ''Crisularia plumosa'' is a colonial bryozoan that forms small bushy clumps, up to high, which are attached to the substrate by a tangled ball of rhizoids. The founding zooid is circular and spineless. As it buds and develops into a colony, a robust central trunk is formed, and branches grow out dichotomously from this in a characteristic spiral fashion, each with fine feathery branchlets. The colony is whitish, or pale tan. The individual zooids are microscopic, about and form two calcified rows on each branchlet; some of the smallest zooids are avicularia, each able to use its mandible and hooked beak to catch prey, which is then passed to the somewhat larger neighbouring autozooids. Distribution and habitat ''Crisularia plumosa'' is native to the northeastern Atlantic Ocean, its range extending from the No ...

Bugulina Turbinata
''Bugulina turbinata'' is a species of bryozoan belonging to the family Bugulidae. It is found in shallow water in the northeastern Atlantic Ocean and the Mediterranean Sea. Description ''Bugulina turbinata'' is a colonial bryozoan that forms small bushy clumps, up to in height. These are orange or pale brown, and are attached to a hard substrate by an extension of the rhizoids at the base. Each frond has branchlets growing out in a spiral arrangement, each with two rows, widening to three to four rows, of zooids. The individual zooids are rectangular, about , with a short spine at each upper corner. The lophophore consists of thirteen tentacles and the avicularia is rounded and projects like a bird's head with a hooked beak, just below the spines. The conspicuous brood chambers are globular, and during the summer, yellow embryos can be seen developing inside. Ecology Developing embryos of ''Bugulina turbinata'' are retained within a brood chamber, and the larvae are only free ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
