Longspine Squirrelfish
The longspine squirrelfish (''Holocentrus rufus'') is a silvery red, sea fish with orange-gold body stripes. One of about 150 species of squirrelfish, their most distinguishing characteristics are their large eyes and the long third spine of the anal fin. It is often included in public aquarium displays. The length of the longspine squirrelfish is about 18 cm (7.8 inches). It lives in coral reefs in tropical and warm temperate seas and eats zoobenthos. It is territorial and uses sounds called "grunts" and "staccatos" to defend its crevice, warn of danger and, in groups, intimidate predators such as the moray eel. The longspine squirrelfish is edible and harvested on a small scale. Identification The body of the longspine squirrelfish is silvery red, with orange-gold body stripes. Its eyes are very large, which is characteristic of all squirrelfish. The rear dorsal fin is pronounced and sticks up. The anal fin has a strongly elongated third spine, from which this squirrelfis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Julius Walbaum
Johann Julius Walbaum (30 June 1724 – 21 August 1799) was a German physician, naturalist and fauna taxonomist. Works As an ichthyologist, he was the first to describe many previously unknown fish species from remote parts of the globe, such as the Great Barracuda (''Sphyraena barracuda''), the Chum salmon (''Oncorhynchus keta'') from the Kamchatka River in Siberia, and the curimatá-pacú (''Prochilodus marggravii'') from the São Francisco River in Brazil. He was also the first to observe gloves as a preventative against infection in medical surgery. In 1758, the gloves he observed were made from the cecum of the sheep, rather than rubber, which had not yet been discovered. Legacy The Natural History Museum in Lübeck, opened in 1893, was based on Walbaum's extensive scientific collection, which was lost during the Second World War World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945.

Squirrelfish
Holocentrinae is a subfamily of Holocentridae containing 40 recognized species and one proposed species. Its members are typically known as squirrelfish and all are nocturnal. All three genera in the subfamily are found in the Atlantic and ''Holocentrus'' is restricted to this ocean. Most species in genera ''Neoniphon'' and ''Sargocentron'' are from the Indo-Pacific region and several of these occur in the Indian Ocean west of the southern tip of India.Randal, J.E. and Heemstra, P.C. 1985"A review of the squirrelfishes of the subfamily Holocentrinae from the Western Indian Ocean and Red Sea" ''Ichthyological Bulletin of the J.L.B. Smith Institute of Ichthyology''; No. 49. J.L.B. Smith Institute of Ichthyology, Rhodes University. A rare example of the fish is featured in Ian Fleming's 1960 James Bond short story, "The Hildebrand Rarity."

Moray Eel
Moray eels, or Muraenidae (), are a family of eels whose members are found worldwide. There are approximately 200 species in 15 genera which are almost exclusively marine, but several species are regularly seen in brackish water, and a few are found in fresh water. The English name, from the early 17th century, derives from Portuguese , which itself derives from Latin , in turn from Greek , ; these are the Latin and Greek names of the Mediterranean moray. Anatomy The dorsal fin extends from just behind the head along the back and joins seamlessly with the caudal and anal fins. Most species lack pectoral and pelvic fins, adding to their serpentine appearance. Their eyes are rather small; morays rely mostly on their highly developed sense of smell, lying in wait to ambush prey. The body is generally patterned. In some species, the inside of the mouth is also patterned. Their jaws are wide, framing a protruding snout. Most possess large teeth used to tear flesh or grasp slipper ...

Monaco
Monaco (; ), officially the Principality of Monaco (french: Principauté de Monaco; Ligurian: ; oc, Principat de Mónegue), is a sovereign city-state and microstate on the French Riviera a few kilometres west of the Italian region of Liguria, in Western Europe, on the Mediterranean Sea. It is bordered by France to the north, east and west. The principality is home to 38,682 residents, of whom 9,486 are Monégasque nationals; it is widely recognised as one of the most expensive and wealthiest places in the world. The official language of the principality is French. In addition, Monégasque (a dialect of Ligurian), Italian and English are spoken and understood by many residents. With an area of , it is the second-smallest sovereign state in the world, after Vatican City. Its make it the most densely-populated sovereign state in the world. Monaco has a land border of and the world's shortest coastline of approximately ; it has a width that varies between . The hig ...

Pelagic Fish
Pelagic fish live in the pelagic zone of ocean or lake waters—being neither close to the bottom nor near the shore—in contrast with demersal fish that do live on or near the bottom, and reef fish that are associated with coral reefs. The marine pelagic environment is the largest aquatic habitat on Earth, occupying 1,370 million cubic kilometres (330 million cubic miles), and is the habitat for 11% of known fish species. The oceans have a mean depth of . About 98% of the total water volume is below , and 75% is below . Moyle and Cech, p. 585 Marine pelagic fish can be divided into coastal (inshore) fish and oceanic (offshore) fish. Coastal pelagic fish inhabit the relatively shallow and sunlit waters above the continental shelf, while oceanic pelagic fish inhabit the vast and deep waters beyond the continental shelf (even though they also may swim inshore). Pelagic fish range in size from small coastal forage fish, such as herrings and sardines, to large apex pre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pristigenys Alta
''Pristigenys alta'', the toro or short bigeye, is a species of fish in the family Priacanthidae. Some anglers refer to this fish as "toro snapper", but it is not a snapper, and only distantly related to the fish of the snapper family. Description The most noticeable characteristic of ''Pristigenys alta'' is its very large eyes. This species is blunt, bright red, and ovate, with a flattened, disk-like body. It is commonly about 20 cm in length, but can grow to maximum length of 30 cm. It has rough scales, and large ventral fins. Distribution This species is found in the Western Atlantic along the east coast of North America from North Carolina southwards, the Gulf of Mexico, in the Caribbean Sea and West Indies. Habitat ''Pristigenys alta'' is a solitary marine fish that lives mainly in reef areas at depths of between 5 and 200 metres. It can also be found on rocky bottoms.

Red Drum
The red drum (''Sciaenops ocellatus''), also known as redfish, channel bass, puppy drum, spottail bass, or simply red, is a game fish found in the Atlantic Ocean from Massachusetts to Florida and in the Gulf of Mexico from Florida to northern Mexico. It is the only species in the genus ''Sciaenops''. The red drum is related to the black drum (''Pogonias cromis''), and the two species are often found near to each other; they can interbreed and form a robust hybrid, and younger fish are often indistinguishable in flavor. Characteristics Red drum are a dark red color on the back, which fades into white on the belly. The red drum has a characteristic eyespot near the tail and is somewhat streamlined. Three-year-old red drum typically weigh 6-8 lb. The largest red drum on record weighed just over 94 lb and was caught in 1984 on Hatteras Island. Male red drum make a knocking or drumming sound during spawning by vibrating their swim bladders. The most distinguishing mark on the red dr ...

Holocentridae
Holocentridae is a family of ray-finned fish, the only family of the order Holocentriformes. The members of the subfamily Holocentrinae are typically known as squirrelfish, while the members of Myripristinae typically are known as soldierfish.Lieske, Ewald, & Robert Myers. 1999. ''Coral Reef Fishes - Caribbean, Indian Ocean, and Pacific Ocean including the Red Sea.'' 2nd edition. In Hawaii, they are known by the Japanese name ''mempachi/menpachi'' (メンパチ) or the Hawaiian ''ʻūʻū''. They are found in tropical parts of the Indian, Pacific and Atlantic Oceans, with the greatest species richness near reefs in the Indo-Pacific. Most are found at depths from the shoreline to , but some, notably the members of the genus ''Ostichthys'', are generally found far deeper. Being largely or entirely nocturnal, they have relatively large eyes. During the day, they typically remain hidden in crevices, caves, or under ledges. Red and silvery colours dominate.

Fish Described In 1792
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Most fis ...
