Drum (fish)
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 ...

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 travel t ...

Gulf Of California
The Gulf of California ( es, Golfo de California), also known as the Sea of Cortés (''Mar de Cortés'') or Sea of Cortez, or less commonly as the Vermilion Sea (''Mar Bermejo''), is a marginal sea of the Pacific Ocean that separates the Baja California Peninsula from the Mexico, Mexican mainland. It is bordered by the states of Baja California, Baja California Sur, Sonora, and Sinaloa with a coastline of approximately . Rivers that flow into the Gulf of California include the Colorado River, Colorado, Fuerte River, Fuerte, Mayo River (Mexico), Mayo, Sinaloa River, Sinaloa, Sonora River, Sonora, and the Yaqui River, Yaqui. The surface of the gulf is about . Maximum depths exceed because of the complex geology, linked to plate tectonics. The gulf is thought to be one of the most diverse seas on Earth and is home to more than 5,000 species of micro-invertebrates. Parts of the Gulf of California are a UNESCO World Heritage Site.

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 .

7 (seven) is the natural number following 6 and preceding 8. It is the only prime number preceding a cube. As an early prime number in the series of positive integers, the number seven has greatly symbolic associations in religion, mythology, superstition and philosophy. The seven Classical planets resulted in seven being the number of days in a week. It is often considered lucky in Western culture and is often seen as highly symbolic. Unlike Western culture, in Vietnamese culture, the number seven is sometimes considered unlucky. It is the first natural number whose pronunciation contains more than one syllable. Evolution of the Arabic digit In the beginning, Indians wrote 7 more or less in one stroke as a curve that looks like an uppercase vertically inverted. The western Ghubar Arabs' main contribution was to make the longer line diagonal rather than straight, though they showed some tendencies to making the digit more rectilinear. The eastern Arabs developed the digit fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bottlenose Dolphin
Bottlenose dolphins are aquatic mammals in the genus ''Tursiops.'' They are common, cosmopolitan members of the family Delphinidae, the family of oceanic dolphins. Molecular studies show the genus definitively contains two species: the common bottlenose dolphin (''Tursiops truncatus'') and the Indo-Pacific bottlenose dolphin (''Tursiops aduncus''). Others, like the Burrunan dolphin (''Tursiops (aduncus) australis''), may be alternately considered their own species or be subspecies of ''T. aduncus''. Bottlenose dolphins inhabit warm and temperate seas worldwide, being found everywhere except for the Arctic and Antarctic Circle regions. Their name derives from the Latin ''tursio'' (dolphin) and ''truncatus'' for their characteristic truncated teeth. Numerous investigations of bottlenose dolphin intelligence have been conducted, examining mimicry, use of artificial language, object categorization, and self-recognition. They can use tools (sponging; using marine sponges to forage ... [...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 system t ...

Tendon
A tendon or sinew is a tough, high-tensile-strength band of dense fibrous connective tissue that connects muscle to bone. It is able to transmit the mechanical forces of muscle contraction to the skeletal system without sacrificing its ability to withstand significant amounts of tension. Tendons are similar to ligaments; both are made of collagen. Ligaments connect one bone to another, while tendons connect muscle to bone. Structure Histologically, tendons consist of dense regular connective tissue. The main cellular component of tendons are specialized fibroblasts called tendon cells (tenocytes). Tenocytes synthesize the extracellular matrix of tendons, abundant in densely packed collagen fibers. The collagen fibers are parallel to each other and organized into tendon fascicles. Individual fascicles are bound by the endotendineum, which is a delicate loose connective tissue containing thin collagen fibrils and elastic fibres. Groups of fascicles are bounded by the epitenon, ... [...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 the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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 (wine), 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 (wine), finish is sometimes marked with sour-cherry notes. In some regions of Valpolicella, producers are using oak (wine), barrel aging to add more structure and complexity to the wine. The small berries of Corvina ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
