Dolabella (gastropod)
''Dolabella'' is a genus of sea slugs or sea hares, marine opisthobranch gastropod mollusks in the family Aplysiidae, the sea hares. Description In the sea hares of the genus ''Dolabella'' the back end of the body has turned into a slanted disc-like shield, with a large, calcified shell buried inside. The color is variable, with specks of green and brown. There are fossil records of † ''Dolabella aldrichi'' from the Early Miocene, found in the Chipola Formation in Florida Species Species within the genus ''Dolabella'' include: * † '' Dolabella aldrichi'' * '' Dolabella auricularia'' Lightfoot, 1786 or Wedge Sea Hare * '' Dolabella gigas'' Rang, 1828 **Distribution : Indian Ocean. **Description : The internal shell has a saucer-shaped extension; armed penis ;Species brought into synonymy: * ''Dolabella aldrichi'' Dall, 1890 †: synonym of '' Floribella aldrichi'' (Dall, 1890) † (original combination) * ''Dolabella andersoni'' Allan, 1941: synonym of '' Dolabella auri ...

Dolabella Auricularia
''Dolabella auricularia'', also known as the wedge sea hare, is a species of large sea slug, a marine opisthobranch gastropod mollusk in the family Aplysiidae Aplysiidae is the only family in the superfamily Aplysioidea, within the clade Anaspidea. These animals are commonly called sea hares because, unlike most sea slugs, they are often quite large, and when they are underwater, their rounded body sh ..., the sea hares. Description ''Dolabella auricularia'' is a rather large species which can reach a length of . It can be recognized by a flattened disk on the posterior surface of the animal. This species can be found with soft pustules, leading to a rather knob-like appearance. It has a short, blunt head. Its body is covered with tubercles and skin flaps. The vestigial, internal shell has a typical ear-like form. Like all sea hares, it ejects a purple ink when disturbed. Distribution ''Dolabella auricularia'' can be found in the Indian Ocean and the western and NW P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aplysiidae
Aplysiidae is the only family in the superfamily Aplysioidea, within the clade Anaspidea. These animals are commonly called sea hares because, unlike most sea slugs, they are often quite large, and when they are underwater, their rounded body shape and the long rhinophores on their heads mean that their overall shape resembles that of a sitting rabbit or hare. Sea hares are however sea snails with shells reduced to a small plate hidden between the parapodia, and some species are extremely large. The Californian black sea hare, ''Aplysia vaccaria'' is arguably the largest living gastropod species, and is certainly the largest living heterobranch gastropod. Description Members of the Aplysiidae have an atrophied inner shell (in contrast with the nudibranchs, which have no shell at all). In ''Aplysia'' and ''Syphonota'', this shell is a soft flattened plate over the visceral rear end, where it is fully or partially enclosed in the mantle skin. In ''Dolabella auricularia'', t ...

Aplysia Depilans
''Aplysia depilans'', the depilatory sea hare, is a species of sea hare or sea slug, a marine opisthobranch gastropod mollusk in the family Aplysiidae. Its name has led to a folk etymology that its consumption caused hair loss. Distribution This sea hare occurs in the eastern Atlantic and the Mediterranean. It can be found mostly in shallow water of about 1.5 to 10 m. It avoids the intertidal zone because the animals cannot absorb atmospheric oxygen and so die after stranding relatively quickly. Occasionally some are trapped in tide pools at low tide. The adults feed primarily on algae of the genus ''Ulva'', especially sea lettuce ''Ulva lactuca''. During the planktonic phase of life they eat single-celled phytoplankton. Description Individuals can grow up to 40 cm long and weighs up to 380 g. Their skin is dark brown to reddish brown, with white to light brown blotches. It has a yellow inner shell that is thinner, flatter and more poorly calcified than other sea hares and m ...

Dolabrifera Dolabrifera
''Dolabrifera dolabrifera'' is a species of sea hare, a marine gastropod mollusc in the family Aplysiidae, the sea hares. ''Dolabrifera dolabrifera,'' otherwise known as a ''Warty Seacat.'' The animal goes by many names, including the common sea hare. The Hawaiian name for ''Dolabrifera dolabrifera, is Kualakai.'' Description & Biology The Seacat is a flat sea hare that grows to about 10 cm long. The maximum recorded length is 108 mm. It is commonly spotty green or brown, but it can also be reddish. The animal's back half is typically wider and rounded, it narrows towards the head.

Floribella Aldrichi
''Floribella'' is a soap opera that was produced in Brazil, Portugal and Chile. Each of those countries had their own cast, but the show had exactly the same name. Although they had the same name, all of them came from the first and original Argentine soap opera called ''Floricienta'', created by Cris Morena. Plot ''Floribella'' is based on the classic story '' Cinderella''. Flor is a pretty, young and poor girl who works for Frederico Fritzenwalden, who falls in love with Flor. However, Frederico is engaged with Delfina, who is a very mean and spoiled woman that fights against anything to marry the soonest possible Frederico and get his money. But like in the fairy tales, the love always wins: Frederico finds out all the truth about Delfina, and all what she did to everyone. In the final week of the soap opera, Frederico dies (he dies differently in each country version), and with this ending, a new story starts with Flor and Conde Máximo Augusto, so this way, the secon ...

Chipola Formation
The Chipola Formation is a Late Oligocene to Early Miocene geologic formation in the Florida Panhandle and member of the Alum Bluff Group. Age Period: Neogene Epoch: Early Miocene to Middle Miocene Faunal stage: Aqitanian ~18.9 to 18.3 mya, calculates to a period of Location The Chipola Formation is found along the Chipola River. Lithography The Chipola Formation is composed of clays, sands and shell beds. These vary from fossil bearing sandy clays to sands, clays, and carbonate beds absent of fossil content with glauconite and phosphate mica which is common. The coloration is from cream to olive gray with mottled reddish brown in the weathered sections. The sands are soft and very fine to coarse with sporadic gravel while carbonate lenses are quite hard. Permeability of the sediments are generally low and are part of the intermediate confining unit/aquifer system. Fossil content The Chipola Formation of the Early Miocene contains one of the most diverse, high-abund ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia.

Gastropod Shell
The gastropod shell is part of the body of a Gastropoda, gastropod or snail, a kind of mollusc. The shell is an exoskeleton, which protects from predators, mechanical damage, and dehydration, but also serves for muscle attachment and calcium storage. Some gastropods appear shell-less (slugs) but may have a remnant within the mantle, or in some cases the shell is reduced such that the body cannot be retracted within it (semi-slug). Some snails also possess an operculum that seals the opening of the shell, known as the Aperture (mollusc), aperture, which provides further protection. The study of mollusc shells is known as conchology. The biological study of gastropods, and other molluscs in general, is malacology. Shell morphology terms vary by species group. Shell layers The gastropod shell has three major layers secreted by the Mantle (mollusc), mantle. The calcareous central layer, tracum, is typically made of calcium carbonate precipitated into an organic matrix known as c ...

Mollusk
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.

Jean-Baptiste Lamarck
Jean-Baptiste Pierre Antoine de Monet, chevalier de Lamarck (1 August 1744 – 18 December 1829), often known simply as Lamarck (; ), was a French naturalist, biologist, academic, and soldier. He was an early proponent of the idea that biological evolution occurred and proceeded in accordance with Naturalism (philosophy), natural laws. Lamarck fought in the Seven Years' War against Prussia, and was awarded a commission for bravery on the battlefield. Posted to Monaco, Lamarck became interested in natural history and resolved to study medicine.#Packard, Packard (1901), p. 15. He retired from the army after being injured in 1766, and returned to his medical studies. Lamarck developed a particular interest in botany, and later, after he published the three-volume work ''Flore françoise'' (1778), he gained membership of the French Academy of Sciences in 1779. Lamarck became involved in the Jardin des Plantes and was appointed to the Chair of Botany in 1788. When the French Nationa ...

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.
