Sciaenidae
Sciaenidae are a family of fish in the order Acanthuriformes. They are commonly called drums or croakers in reference to the repetitive throbbing or drumming sounds they make. The family consists of about 286 to 298 species in about 66 to 70 genera. Characteristics A sciaenid has a long dorsal fin reaching nearly to the tail, and a notch between the rays and spines of the dorsal, although the two parts are actually separate. Drums are somberly coloured, usually in shades of brown, with a lateral line on each side that extends to the tip of the caudal fin. The anal fin usually has two spines, while the dorsal fins are deeply notched or separate. Most species have a rounded or pointed caudal fin. The mouth is set low and is usually inferior. Their croaking mechanism involves the beating of abdominal muscles against the swim bladder. Sciaenids are found worldwide, in both fresh and salt water, and are typically benthic carnivores, feeding on invertebrates and smaller fish. They ...

Aplodinotus
The freshwater drum, ''Aplodinotus grunniens'', is a fish endemic to North and Central America. It is the only species in the genus ''Aplodinotus'', and is a member of the family Sciaenidae. It is the only North American member of the group that inhabits freshwater for its entire life.Fish of the Great Lakes: Wisconsin Sea Grant. Freshwater Drum Aplodinotus grunniens. Wisconsin Sea Grant 2002.http://seagrant.wisc.edu/greatlakesfish/drum.html. Its generic name, ''Aplodinotus'', comes from Greek meaning "single back", and the specific epithet, ''grunniens'', comes from a Latin word meaning "grunting". It is given to it because of the grunting noise that mature males make. This noise comes from a special set of muscles within the body cavity that vibrate against the swim bladder. The purpose of the grunting is unknown, but due to it being present in only mature males and during the spawning season, it is assumed to be linked to spawning. The drum typically weighs .

Atlantic Croaker
The Atlantic croaker (''Micropogonias undulatus'') is a species of marine ray-finned fish belonging to the family Sciaenidae and is closely related to the black drum ('' Pogonias cromis''), the silver perch ('' Bairdiella chrysoura''), the spot croaker (''Leiostomus xanthurus''), the red drum ('' Sciaenops ocellatus''), the spotted seatrout (''Cynoscion nebulosus''), and the weakfish (''Cynoscion regalis''). It is commonly found in sounds and estuaries from Massachusetts to the Gulf of Mexico. Description The name croaker is descriptive of the noise the fish makes by vibrating strong muscles against its swim bladder, which acts as a resonating chamber much like a ball. The Atlantic croaker is the loudest of the drum family. It is also referred to as a hardhead, with smaller ones called pin heads. During spawning season (August to October), croakers turn a deep golden color, from this comes the name golden croaker. Beginning in August, tiny young enter the Chesapeake Bay and trave ...

Small Yellow Croaker
''Larimichthys polyactis'', called the redlip croaker, small yellow croaker, little yellow croaker or yellow corvina, is a species of croaker native to the western Pacific, generally in temperate waters such as the East China Sea and the Yellow Sea. Evolution Phylogenomic studies indicate this species emerged from the same common ancestor of '' L. crocea'' around 25.4 million years ago. Diet They are benthopelagic feeders that usually eat shrimp, zooplankton, or sometimes small fishes. Habitat They remain in shallow waters above 120 m, but avoid brackish conditions. They are typically found where the sea floor is sand or mud. Morphology Males can reach 42 cm while the common length is about 30 cm. Their body shape is almost rectangular. They have red lips, grey gold body, gold belly and light yellow fins. The inside of its mouth is white and the gill slit is black. In its head are two hard, pale, white bones that keep balance when they swim, which is also us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spotted Drum
The spotted drum or spotted ribbonfish (''Equetus punctatus''), is a species of marine fish in the family Sciaenidae.Lieske & Myers,''Coral reef fishes'', Princeton University Press, 2009, The spotted drum is widespread throughout the tropical waters of the occidental Atlantic Ocean from South Florida to Brazil including by the way the Bermuda, the Bahamas, the Gulf of Mexico and the Caribbean Sea. It is frequently observed during the day under ledges or near the opening of small caves, at depths between 3 and , where it swims in repetitive patterns. A nocturnal feeder, it leaves the protection of its daily shelter at night to feed mainly on small crustaceans and Polychaete worm Polychaeta () is a paraphyletic class of generally marine annelid worms, commonly called bristle worms or polychaetes ().

Pareques Acuminatus
''Pareques acuminatus'', (the high-hat, cubbyu, streaked ribbonfish or striped drum), is a small fish, usually between 6 and 9 inches, that can occasionally be found on coral reefs in the middle western Atlantic Ocean, in the Caribbean, the Gulf of Mexico, Florida and the Bahamas. High-hats are typically black and white or dark brown and white. Habitat Young high-hats typically live in rocks and coral hidden from predators. Generally they inhabit reef A reef is a ridge or shoal of rock, coral or similar relatively stable material, lying beneath the surface of a natural body of water. Many reefs result from natural, abiotic processes— deposition of sand, wave erosion planing down rock o ... areas.

Corvina (Rio De Janeiro, Brazil, 11 July 1865)
Corvina is an Italian wine grape variety that is sometimes also referred to as Corvina Veronese or Cruina. The total global wine-growing area in 2010 was , all of which is grown in the Veneto region of northeast Italy, except for planted in Argentina. Corvina is used with several other grapes to create the light red regional wines Bardolino and Valpolicella that have a mild fruity flavor with hints of almond. These blends include Corvinone, Rondinella, and Molinara, and Rossignola for the latter wine. It is also used for the production of Amarone and Recioto. Wines Corvina produces light to medium body wines with a light crimson coloring. The grapes' naturally high acidity can make the wine somewhat tart with a slight, bitter almond note. The finish is sometimes marked with sour-cherry notes. In some regions of Valpolicella, producers are using barrel aging to add more structure and complexity to the wine. The small berries of Corvina are low in tannins and color extrac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mating Call
A mating call is the auditory signal used by animals to attract mates. It can occur in males or females, but literature is abundantly favored toward researching mating calls in females. In addition, mating calls are often the subject of mate choice, in which the preferences of one gender for a certain type of mating call can drive sexual selection in a species. This can result in sympatric speciation of some animals, where two species diverge from each other while living in the same environment. There are many different mechanisms to produce mating calls, which can be broadly categorized into vocalizations and mechanical calls. Vocalizations are considered as sounds produced by the larynx and are often seen in species of birds, mammals, amphibians, and insects. Mechanical calls refer to any other type of sound that the animal produces using unique body parts and/or tools for communication with potential mates. Examples include crickets that vibrate their wings, birds that flap thei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Estrous Cycle
The estrous cycle (, originally ) is the set of recurring physiological changes that are induced by reproductive hormones in most mammalian therian females. Estrous cycles start after sexual maturity in females and are interrupted by anestrous phases, otherwise known as "rest" phases, or by pregnancies. Typically, estrous cycles repeat until death. These cycles are widely variable in duration and frequency depending on the species.Bronson, F. H., 1989. Mammalian Reproductive Biology. University of Chicago Press, Chicago, IL, USA. Some animals may display bloody vaginal discharge, often mistaken for menstruation. Many mammals used in commercial agriculture, such as cattle and sheep, may have their estrous cycles artificially controlled with hormonal medications for optimum productivity. The male equivalent, seen primarily in ruminants, is called rut. Differences from the menstrual cycle Mammals share the same reproductive system, including the regulatory hypothalamic s ...
