Mene Grande
The moonfish of the genus ''Mene'', the sole extant genus of the family Menidae, are disk-shaped fish which bear a vague resemblance to gourami, thanks to their thread-like pelvic fins. Today, the genus is represented only by '' Mene maculata'' of the Indo-Pacific, where it is a popular food fish, especially in the Philippines, where it is known as ''bilong-bilong'', ''chabita'', ''hiwas'' or ''tahas''.Small-scale fisheries of San Miguel Bay, Philippines: options for management and research. . As a genus, ''Mene'' has a long fossil history, with species found in marine sediments throughout the Cenozoic Era. The earliest accepted species, '' M. purdyi'' from the Paleocene of Peru, resemble later species, such as '' M. rhombea'' of the Monte Bolca lagerstätte, and even the living species, ''M. maculata''. Experts remain undecided whether the Tunisian species, '' M. phosphatica'' is from the Lower Paleocene, thus making it older than ''M. purdyi'', or whether it is from the Yp ...

Mene Maculata
''Mene maculata'', the moonfish, is the only extant member of the genus ''Mene'' and of the family Menidae. The body is highly compressed laterally and very deep vertically. The ventral profile is steep, with a sharp ventral edge. The caudal (tail) fin is deeply forked. The mouth is small and protrusible. The body is silvery below and blue-green on the back, with three to four rows of dark gray spots on the upper side. The first two rays of the pelvic fin are greatly elongated, forming a prominent backward-pointing process on the underside of the fish. The moonfish is native to the Indian Ocean, including the Red Sea and Persian Gulf, and in the western Pacific where they can be found near the bottom in brackish and marine waters in the vicinity of reefs. They occur at depths of from . This species can reach a length of TL. It is a commercially important species, being easy to dry without having to be salted.

Bolca
Bolca is a village in the Veneto, on the southern margin of the Italian Alps. It is a ''frazione'' of the ''comune'' of Vestenanova, in the province of Verona. The area is famous for the marine fossils from the lagerstätte of ''Monte Bolca''. It was one of the first fossil sites with high quality preservation known to Europeans, and is still an important source of fossils from the Eocene. Geography Bolca lies in the Lessini Alps. Monte Bolca was originally at the bottom of the Tethys Ocean before being uplifted from the ocean floor during the formation of the Alps. This happened in two stages, one 24 million years ago and one between 30 and 50 million years ago. History The area was settled in prehistoric times, there are remains of a hill fort on Monte Purga dating from around 1000 BC. The Romans were active in the area, and by 1000AD the village had come under the control of a convent of the Augustinian Eremitani. In the thirteenth century the fortunes of the Vestenanova are ...

Remora
The remora (), sometimes called suckerfish, is any of a family (Echeneidae) of ray-finned fish in the order Carangiformes. Depending on species, they grow to long. Their distinctive first dorsal fins take the form of a modified oval, sucker-like organ with slat-like structures that open and close to create suction and take a firm hold against the skin of larger marine animals. The disk is made up of stout, flexible membranes that can be raised and lowered to generate suction. By sliding backward, the remora can increase the suction, or it can release itself by swimming forward. Remoras sometimes attach to small boats, and have been observed attaching to divers as well. They swim well on their own, with a sinuous, or curved, motion. Characteristics Remora front dorsal fins have evolved to enable them to adhere by suction to smooth surfaces, and they spend most of their lives clinging to a host animal such as a whale, turtle, shark or ray. It is probably a mutualistic arrang ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dolphinfish
''Coryphaena'' is a genus of marine ray-finned fishes known as the dolphinfishes, and is currently the only known genus in the family Coryphaenidae. The generic name is from Greek κορυφή (''koryphē'', "crown, top") and -αινα (-''aina'', feminine suffix). Species in this genus have compressed heads and single dorsal fins that run the entire length of the fishes' bodies. Dolphinfish are aggressive predatory fish that actively prey upon oceanic forage fishes, while in turn serving as a primary food source for many larger pelagic predators. The dolphinfish can reach up to about , and are some of the fastest-growing species in the ocean. Despite the name, dolphinfishes are unrelated to and look unlike dolphins (which are marine mammals with pointed snouts), and commercially their meat is often labeled with its Hawaiian name mahi-mahi to reduce possible public confusion. The origin of the name "dolphinfish" is recent, to avoid confusion with dolphins, as the traditional nam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pomfret
Pomfrets are perciform fishes belonging to the family Bramidae. The family currently includes 20 species across seven genera. Several species are important food sources for humans, especially ''Brama brama'' in South Asia. The earlier form of the pomfret's name was "", a word which probably ultimately comes from Portuguese ''pampo'', referring to various fish such as the blue butterfish ('' Stromateus fiatola''). The fish meat is white in color. Distribution They are found globally in the Atlantic, Indian, and Pacific Oceans, as well as numerous seas including the Norwegian, Mediterranean, and Sea of Japan. Nearly all species can be found in the high seas. However, fishes in the genera ''Pterycombus'' and ''Pteraclis'' tend to be found off continental shelves. Further, fishes in the genus ''Eumegistus'' are hypothesized to be largely benthic and found to occupy deep water shelves. Some species of pomfrets are also known as monchong, specifically in Hawaiian cuisine. Genera T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing Great American Interchang ...

Strata
In geology and related fields, a stratum ( : strata) is a layer of rock or sediment characterized by certain lithologic properties or attributes that distinguish it from adjacent layers from which it is separated by visible surfaces known as either '' bedding surfaces'' or ''bedding planes''.Salvador, A. ed., 1994. ''International stratigraphic guide: a guide to stratigraphic classification, terminology, and procedure. 2nd ed.'' Boulder, Colorado, The Geological Society of America, Inc., 215 pp. . Prior to the publication of the International Stratigraphic Guide, older publications have defined a stratum as either being either equivalent to a single bed or composed of a number of beds; as a layer greater than 1 cm in thickness and constituting a part of a bed; or a general term that includes both ''bed'' and ''lamina''.Neuendorf, K.K.E., Mehl, Jr., J.P., and Jackson, J.A. , eds., 2005.

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.

Otolith
An otolith ( grc-gre, ὠτο-, ' ear + , ', a stone), also called statoconium or otoconium or statolith, is a calcium carbonate structure in the saccule or utricle of the inner ear, specifically in the vestibular system of vertebrates. The saccule and utricle, in turn, together make the ''otolith organs''. These organs are what allows an organism, including humans, to perceive linear acceleration, both horizontally and vertically (gravity). They have been identified in both extinct and extant vertebrates. Counting the annual growth rings on the otoliths is a common technique in estimating the age of fish. Description Endolymphatic infillings such as otoliths are structures in the saccule and utricle of the inner ear, specifically in the vestibular labyrinth of all vertebrates (fish, amphibians, reptiles, mammals and birds). In vertebrates, the saccule and utricle together make the ''otolith organs''. Both statoconia and otoliths are used as gravity, balance, movement, and d ...

Neogene
The Neogene ( ), informally Upper Tertiary or Late Tertiary, is a geologic period and system that spans 20.45 million years from the end of the Paleogene Period million years ago ( Mya) to the beginning of the present Quaternary Period Mya. The Neogene is sub-divided into two epochs, the earlier Miocene and the later Pliocene. Some geologists assert that the Neogene cannot be clearly delineated from the modern geological period, the Quaternary. The term "Neogene" was coined in 1853 by the Austrian palaeontologist Moritz Hörnes (1815–1868). During this period, mammals and birds continued to evolve into modern forms, while other groups of life remained relatively unchanged. The first humans (''Homo habilis'') appeared in Africa near the end of the period. Some continental movements took place, the most significant event being the connection of North and South America at the Isthmus of Panama, late in the Pliocene. This cut off the warm ocean currents from the Pacific to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paleogene
The Paleogene ( ; British English, also spelled Palaeogene or Palæogene; informally Lower Tertiary or Early Tertiary) is a geologic period, geologic period and system that spans 43 million years from the end of the Cretaceous Period million years ago (annum, Mya) to the beginning of the Neogene Period Mya. It is the beginning of the Cenozoic Era of the present Phanerozoic Eon. The earlier term Tertiary Period was used to define the span of time now covered by the Paleogene Period and subsequent Neogene Period; despite no longer being recognised as a formal stratigraphy, stratigraphic term, 'Tertiary' is still widely found in earth science literature and remains in informal use. Paleogene is often abbreviated "Pg" (but the United States Geological Survey uses the abbreviation PE for the Paleogene on the Survey's geologic maps). During the Paleogene, evolution of mammals, mammals diversified from relatively small, simple forms into a large group of diverse animals in the wake of ...
