Sardinella
''Sardinella'' is a genus of fish in the family Dorosomatidae found in the Atlantic, Indian and Pacific Oceans. 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 27 recognized species in this genus: * '' Sardinella albella'' (Valenciennes, 1847) (White sardinella) * '' Sardinella alcyone'' Hata & Motomura, 2019 (Blueback sardinella) * '' Sardinella atricauda'' ( Günther, 1868) (Bleeker's blacktip sardi ...

Sardinella Maderensis
''Sardinella maderensis'' (Madeiran sardinella) is a species of small ray-finned fish in the genus ''Sardinella'' which is found in the Eastern Atlantic and Southeastern Mediterranean. it is a silvery fish similar to the round sardinella (''Sardinella aurita''), but can be distinguished from that species by having gray caudal fins with black tips. It feeds on phytoplankton and fish larvae and is a pelagic, oceanodromous species that forms schools in coastal waters, often mixed with ''S. aurita''. The International Union for Conservation of Nature has rated this fish's conservation status as " vulnerable". Diagnostic features ''S. madarensis'' is a distinctly elongate ''Sardinella'' while also having a variably protruding belly. These fish have a median number of gill rakers and their upper pectoral fin rays are white on the outer side with a black membrane in between. They are very hard to distinguish from ''Sardinella aurita'' except that these fish have only 7 rays on their pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sardinella Albella
The white sardinella (''Sardinella albella''), also known as deep-bodied sardine, perforated-scale sardine or short-bodied sardine, is a species of ray-finned fish in the genus ''Sardinella''. It is an important food fish, which can be feed as dried, salted, or fresh forms. Description It is distributed throughout the Indo-West Pacific oceans from Madagascar, around India, Sri Lanka, and eastward to Indonesia, Taiwan and south to Papua New Guinea. It is a small schooling fish found in depth of 20-50m. Maximum length do not exceed 21.5 cm. The fish has 13 to 21 dorsal soft rays and 12 to 23 anal soft rays. There is a dark spot at origin part of dorsal fin. It feeds on small planktons.

Estuary
An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone. Estuaries are subject both to marine influences such as tides, waves, and the influx of saline water, and to fluvial influences such as flows of freshwater and sediment. The mixing of seawater and freshwater provides high levels of nutrients both in the water column and in sediment, making estuaries among the most productive natural habitats in the world. Most existing estuaries formed during the Holocene epoch with the flooding of river-eroded or glacially scoured valleys when the sea level began to rise about 10,000–12,000 years ago. Estuaries are typically classified according to their geomorphological features or to water-circulation patterns. They can have many different names, such as ba ...

Ocean
The ocean is the body of salt water that covers approximately 70.8% of Earth. The ocean is conventionally divided into large bodies of water, which are also referred to as ''oceans'' (the Pacific, Atlantic, Indian Ocean, Indian, Southern Ocean, Antarctic/Southern, and Arctic Ocean),"Ocean."

Lagoon
A lagoon is a shallow body of water separated from a larger body of water by a narrow landform, such as reefs, barrier islands, barrier peninsulas, or isthmuses. Lagoons are commonly divided into ''coastal lagoons'' (or ''barrier lagoons'') and ''atoll lagoons''. They have also been identified as occurring on mixed-sand and gravel coastlines. There is an overlap between bodies of water classified as coastal lagoons and bodies of water classified as Estuary, estuaries. Lagoons are common coastal features around many parts of the world. Definition and terminology Lagoons are shallow, often elongated bodies of water separated from a larger body of water by a shallow or exposed shoal, reef, coral reef, or similar feature. Some authorities include fresh water bodies in the definition of "lagoon", while others explicitly restrict "lagoon" to bodies of water with some degree of salinity. The distinction between "lagoon" and "estuary" also varies between authorities. Richard A. Davis J ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fin Ray
Fins are moving appendages protruding from the body of fish that interact with water to generate thrust and help the fish swim. Apart from the tail or caudal fin, fish fins have no direct connection with the back bone and are supported only by muscles. Fish fins are distinctive anatomical features with varying structures among different clades: in ray-finned fish (Actinopterygii), fins are mainly composed of bony spines or rays covered by a thin stretch of scaleless skin; in lobe-finned fish (Sarcopterygii) such as coelacanths and lungfish, fins are short rays based around a muscular central bud supported by jointed bones; in cartilaginous fish (Chondrichthyes) and jawless fish (Agnatha), fins are fleshy " flippers" supported by a cartilaginous skeleton. Fins at different locations of the fish body serve different purposes, and are divided into two groups: the midsagittal ''unpaired fins'' and the more laterally located ''paired fins''. Unpaired fins are predominantly ass ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
