Baixa Da Ponta Dos Rosais
The Baixa da Ponta dos Rosais is an oceanic plateau located north-northwest off the coast of Ponta dos Rosais, a promontory in the municipality of Velas on the island of São Jorge in the Portuguese archipelago of the Azores. It is located approximately from the coast and from the port of Velas. It is a popular destination for divers frequenting the Azores. Geography As part of the northern civil parish of Rosais, Ponta dos Rosais is an extension of the north-northwest and south-southeast fissural formation of the island, along a fault system that extends from São Miguel to São Jorge, called the Terceira Rift. Effusive and explosive submarine eruptions across these fissural faults gave rise to the long, slender island of São Jorge. Oceanic plateaus extending into the ocean north and south of São Jorge resulted from these formative volcanic and seismic forces. The Baixa is one of these plateaus made of submerged basalt cliffs created by fissural tectonics, with accentuat ...

Rosais Islets
The Rosais Islets ( pt, Ilhéus dos Rosais; literally, ''Islets of the Rosaries'') are two uninhabited rocky islets located just off the extreme northwestern coast of the island of São Jorge in the Portuguese archipelago of the Azores. Geography The Rosais Islets are two small, basaltic volcanic stacks located immediately off Ponta dos Rosais, the extreme northwestern point of São Jorge. The islets arise from an oceanic plateau called Baixa da Ponta dos Rosais, which itself is part of the Terceira Rift. Rosais, a civil parish within the larger municipality of Velas, is the settlement nearest the islets. Biome The waters around the Rosais Islets and Baixa da Ponta dos Rosais are biodiverse. They are home to various fish including anchovy, Atlantic bonito, Atlantic goliath grouper, bluefish, European hake, frigate tuna, longfin yellowtail, needlefish, red scorpionfish, sawfish, skipjack tuna, vadigo, and yellowmouth barracuda. Common bottlenose dolphins and logg ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Stypopodium Zonale
''Stypopodium zonale'' is a species of thalloid brown alga in the family Dictyotaceae. It is found in shallow waters in the Caribbean Sea and in various other tropical and sub-tropical seas around the world. Description ''Stypopodium zonale'' is a golden brown or olive-coloured seaweed growing to a length of about . It has smooth, broad blades with squared-off ends that grow in a fan shape. As the blade gets bigger it splits into segments wide. The larger the plant, the greater the degree of splitting. Bands of different coloured material develop parallel to the growing edge including an iridescent green band that appears every few centimetres. This gives the seaweed an attractive zoned appearance. It is attached to rock by a rhizoidal holdfast and often forms dense beds, the leathery but flexible fronds swaying with the movement of the surrounding water. Distribution and habitat ''Stypopodium zonale'' is found in shallow areas of the sea around the coasts of Africa, the Cana ...

Sawfish
Sawfish, also known as carpenter sharks, are a family of rays characterized by a long, narrow, flattened rostrum, or nose extension, lined with sharp transverse teeth, arranged in a way that resembles a saw. They are among the largest fish with some species reaching lengths of about . They are found worldwide in tropical and subtropical regions in coastal marine and brackish estuarine waters, as well as freshwater rivers and lakes. They are endangered. They should not be confused with sawsharks (order Pristiophoriformes) or the extinct sclerorhynchoids (order Rajiformes) which have a similar appearance, or swordfish (family Xiphiidae) which have a similar name but a very different appearance. Sawfishes are relatively slow breeders and the females give birth to live young. They feed on fish and invertebrates that are detected and captured with the use of their saw. They are generally harmless to humans, but can inflict serious injuries with the saw when captured and defend ...

Scorpaena Scrofa
''Scorpaena scrofa'', the red scorpionfish, bigscale scorpionfish, large-scaled scorpion fish, or rascasse is a venomous marine species of ray-finned fish in the family Scorpaenidae, the scorpionfishes. It is found in the eastern Atlantic Ocean and the western Indian Ocean. Taxonomy ''Scorpaena scrofa'' was first formally described in 1758 by Carl Linnaeus in the 10th edition of his ''Systema Naturae'' in which he gave the type localities as the Mediterranean Sea at Rome and Marseille. The specific name ''scrofa'' means "a breeding sow" in Latin, presumed to derive from ''scrofano'' and ''scrofanello'', which are Italian names for the black scorpionfish (''S. porcus'') and this species, similar to the Old English "hogfish", possible an allusion to Renaissance mistranslations of Athenaeus' observation that scorpionfishes fed on algae or weed, that led to the belief that these fishes live and feed on mud.

Needlefish
Needlefish (family Belonidae) or long toms are piscivorous fishes primarily associated with very shallow marine habitats or the surface of the open sea. Some genera include species found in marine, brackish, and freshwater environments (e.g., ''Strongylura''), while a few genera are confined to freshwater rivers and streams, including '' Belonion'', '' Potamorrhaphis'', and ''Xenentodon''. Needlefish closely resemble North American freshwater gars (family Lepisosteidae) in being elongated and having long, narrow jaws filled with sharp teeth, and some species of needlefishes are referred to as gars or garfish despite being only distantly related to the true gars. In fact, the name "garfish" was originally used for the needlefish ''Belone belone'' in Europe and only later applied to the North American fishes by European settlers during the 18th century. Description Needlefish are slender, ranging from in length. They have a single dorsal fin, placed far back on the body, almost o ...

Longfin Yellowtail
The longfin yellowtail (''Seriola rivoliana''), also known as the almaco or silvercoat jack, deep-water, falcate, European or highfin amberjack, rock salmon, longfin or yellow kingfish, is a game fish of the family Carangidae; they are in the same family as yellowtail and amberjack. They are carnivorous and feed, both day and night, on other, smaller fish such as baitfish and small squid. The flesh is thick and dense, like tuna, and easily may be passed off for white albacore if prepared as sushi. Taxonomy Achille Valenciennes, and Georges Cuvier published the first description of this species in 1833, although Cuvier died in 1832. Valenciennes and Cuvier together described many fish species, most notably in the 22-volume, ''Histoire naturelle des poissons'', (Natural History of Fish). Description The longfin yellowtail has a less elongated, more flattened body than most jack species. Their dorsal fin and anal fins are elongated, and their outer edges have a definite sic ...

Frigate Tuna
The frigate tuna, frigate mackerel or alagaduwa (''Auxis thazard'') is a species of tuna, in the family Scombridae, found around the world in tropical oceans. The eastern Pacific population is now regarded as a separate species by some authorities, ''Auxis brachydorax''. Parasites As most fishes, the frigate tuna harbours a number of parasites Parasitism is a close relationship between species, where one organism, the parasite, lives on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life. The entomologist E. O. Wilson ha .... Among these are a series of digeneans, which are parasititic within the intestine.

Merluccius Merluccius
''Merluccius merluccius'', the European hake, is a merluccid hake of the genus ''Merluccius''. Other vernacular names include Cornish salmon and herring hake. It is a predatory species which was often netted alongside one of its favoured prey, the Atlantic herring, thus the latter common name. It is found in the eastern Atlantic from the Norway and Iceland south to Mauritania and into the Mediterranean Sea. It is an important species in European fisheries and is heavily exploited with some populations thought to be being fished unsustainably. Description ''Merluccius merluccius'' is a slim-bodied fish with a large head and large jaws on which are set a number of large curved teeth, the lower jaw has two rows of teeth and the upper jaw has one row. The inside of the mouth and the branchial cavity are black. The body is at its widest just behind its head.

Bluefish
The bluefish (''Pomatomus saltatrix'') is the only extant species of the family Pomatomidae. It is a marine pelagic fish found around the world in temperate and subtropical waters, except for the northern Pacific Ocean. Bluefish are known as tailor in Australia and New Zealand, elf and shad in South Africa. It is a popular gamefish and food fish. The bluefish is a moderately proportioned fish, with a broad, forked tail. The spiny first dorsal fin is normally folded back in a groove, as are its pectoral fins. Coloration is a grayish blue-green dorsally, fading to white on the lower sides and belly. Its single row of teeth in each jaw is uniform in size, knife-edged, and sharp. Bluefish commonly range in size from seven-inch (18-cm) "snappers" to much larger, sometimes weighing as much as 40 lb (18 kg), though fish heavier than 20 lb (9 kg) are exceptional.

Atlantic Bonito
The Atlantic bonito (''Sarda sarda'') is a large mackerel-like fish of the family Scombridae. It is common in shallow waters of the Atlantic Ocean, the Mediterranean Sea, and the Black Sea, where it is an important commercial and game fish. Description Atlantic bonito belong to a group which have the dorsal fins very near, or separated by a narrow interspace. Its body is completely scaled, with those scales in the pectoral fin area and the lateral line usually larger in size. Bonitos (fishes in the genus ''Sarda'') differ from tuna by their compressed bodies, their lack of teeth on the roof of the mouth, and certain differences in colouration. Atlantic bonito share Atlantic waters with the striped bonito, '' Sarda orientalis'' (the Atlantic population of which is sometimes considered a separate species, ''Sarda velox''). The striped bonito has been taken on the Atlantic coast as far north as Cape Cod. It is similar in its habits, but somewhat smaller than the more common Atl ...
