Sardinella
''Sardinella'' is a genus of fish in the family Clupeidae found in the Atlantic, Indian and Pacific Ocean. They are abundant in warmer waters of the tropical and subtropical oceans. Adults are generally coastal, schooling, marine fish but juveniles are often found in lagoons and estuaries. These species are distinguished by their ranges and by specific body features, but they are often confused with one another. Fish of the genus have seven to 14 striped markings along the scales of the top of the head. The paddle-shaped supramaxilla bones are characteristic; they separate ''Sardinella'' from other genera and their shapes help distinguish species. They have paired predorsal scales and enlarged fin rays. Species There are currently 24 recognized species in this genus: * '' Sardinella albella'' (Valenciennes, 1847) (White sardinella) * '' Sardinella atricauda'' ( Günther, 1868) (Bleeker's blacktip sardinella) * '' Sardinella aurita'' Valenciennes, 1847 (Round sardinella) * '' Sa ...

Sardinella Brasiliensis
''Sardinella brasiliensis'', (Brazilian sardinella or orangespot sardine) is a species of ray-finned fish in the genus Sardinella. ''S. brasilensis'' are extremely hard to distinguish from ''Sardinella aurita'' and are combined in most studies and catch estimates. They spawn in coastal areas during late spring and summer. The most dense spawning periods are in December and January. From 1973 to 1990 the catch in Venezuela was down from 228000 tons to 31000 tons. These fish are present in the Western Atlantic (including the Gulf of Mexico, Caribbean, West Indies all the way down to Brazil Distinguishing features The standard length of these sardinella is around 20 cm. ''S. brasiliensis'' is similar to their close relative ''S. aurita'' but ''S. brasiliensis'' have two peak spawning seasons. It is important to differentiate this species from ''S. aurita''. Some of the features that make them unique include the anterior gillrakers (see List of ichthyology terms) which are cur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sardinella Aurita
The round sardinella (''Sardinella aurita'') is a species of ray-finned fish in the genus ''Sardinella'' found in both sides of the Atlantic Ocean and the Mediterranean Sea. ''S. aurita'' went through a large boom in catch population around 1990. However, its numbers have been very stable through the last several years. ''S. aurita'' inhabits warm waters. It is a small, pelagic species that lives in tropical and subtropical waters of the western and eastern Atlantic Ocean, the Pacific Ocean, the Mediterranean, and occasionally, the Black Sea. The gonads start to develop in April and are fully mature one month later. Plankton in spawning regions are full of eggs and larvae from the end of June into September. Diagnostic features ''Sardinella aurita'' has a particularly elongated body, a relatively rounded belly, and a large number of fine gill rakers (up to 160). This is one of the largest ''Sardinella'' species, averaging 23 to 28 cm. It has eight pelvic fin rays. It has f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the " New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N.

Maxilla
The maxilla (plural: ''maxillae'' ) in vertebrates is the upper fixed (not fixed in Neopterygii) bone of the jaw formed from the fusion of two maxillary bones. In humans, the upper jaw includes the hard palate in the front of the mouth. The two maxillary bones are fused at the intermaxillary suture, forming the anterior nasal spine. This is similar to the mandible (lower jaw), which is also a fusion of two mandibular bones at the mandibular symphysis. The mandible is the movable part of the jaw. Structure In humans, the maxilla consists of: * The body of the maxilla * Four processes ** the zygomatic process ** the frontal process of maxilla ** the alveolar process ** the palatine process * three surfaces – anterior, posterior, medial * the Infraorbital foramen * the maxillary sinus * the incisive foramen Articulations Each maxilla articulates with nine bones: * two of the cranium: the frontal and ethmoid * seven of the face: the nasal, zygomatic, lacrimal ...
