Leather Jack
The leatherjacket fish or leather jack, ''Oligoplites saurus'', is a species of jack in the family Carangidae. Leather jack may also refer to other members of the Carangidae, such as the pilot fish. The largest are about a foot long. Distribution There are two subspecies of ''Oligoplites saurus''. The nominate subspecies ''O.s. saurus'' is distributed in the western Atlantic Ocean from Chatham, Massachusetts south along the U.S. coast, throughout the Gulf of Mexico and Caribbean Sea, and along the South American coast to Rio Grande do Sul, Brazil. The other subspecies ''O. s. inornatus'' is found in the eastern Pacific Ocean from southern Baja California, much of the Gulf of California to Ecuador, including the Galapagos and Malpelo Islands. Feeding It voraciously devours small fish and shrimp, often in company with larger predatory species. Leatherjackets feed on small fish including the silver perch. As food Traditionally, the leather jacket has not been eaten, but recently, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marcus Elieser Bloch
Marcus Elieser Bloch (1723–1799) was a German physician and naturalist who is best known for his contribution to ichthyology through his multi-volume catalog of plates illustrating the fishes of the world. Brought up in a Hebrew-speaking Jewish family, he learned German and Latin and studied anatomy before settling in Berlin as a physician. He amassed a large natural history collection, particularly of fish specimens. He is generally considered one of the most important ichthyology, ichthyologists of the 18th century, and wrote many papers on natural history, comparative anatomy, and physiology. Life Bloch was born at Ansbach in 1723 where his father was a Torah writer and his mother owned a small shop. Educated at home in Hebrew literature he became a private tutor in Hamburg for a Jewish surgeon. Here he learned German, Latin and anatomy. He then studied medicine in Berlin and received a doctorate in 1762 from Frankfurt (Oder), Frankfort on the Oder with a treatise on skin dis ...

Baja California
Baja California (; 'Lower California'), officially the Free and Sovereign State of Baja California ( es, Estado Libre y Soberano de Baja California), is a state in Mexico. It is the northernmost and westernmost of the 32 federal entities of Mexico. Before becoming a state in 1952, the area was known as the North Territory of Baja California (). It has an area of (3.57% of the land mass of Mexico) and comprises the northern half of the Baja California Peninsula, north of the 28th parallel, plus oceanic Guadalupe Island. The mainland portion of the state is bordered on the west by the Pacific Ocean; on the east by Sonora, the U.S. state of Arizona, and the Gulf of California; on the north by the U.S. state of California; and on the south by Baja California Sur. The state has an estimated population of 3,769,020 as of 2020, significantly higher than the sparsely populated Baja California Sur to the south, and similar to San Diego County, California, to its north. Over 75% of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Of Mexican Pacific Coast
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 f ...

Oligoplites
''Oligoplites'' is a genus of carangid leatherjackets native to warmer seas off the Americas, including the East Pacific, West Atlantic, Caribbean Sea and Gulf of Mexico. Species The currently recognized species in this genus are: * ''Oligoplites altus'' ( Günther, 1868) (longjaw leatherjacket) * ''Oligoplites palometa'' (G. Cuvier, 1832) (Maracaibo leatherjacket) * ''Oligoplites refulgens'' C. H.

Portunus Pelagicus
''Portunus pelagicus'', also known as the flower crab, blue crab, blue swimmer crab, blue manna crab or sand crab, ''rajungan'' in Indonesian, and ''alimasag'' in Tagalog, Kapampangan, and Pangasinan, is a large crab found in the intertidal estuaries around most of Australia and east to New Caledonia. Description The males are bright blue in color with white spots and with characteristically long chelipeds, while the females have a duller green/brown, with a more rounded carapace. The carapace can be up to wide. Behaviour They stay buried under sand or mud most of the time, particularly during the daytime and winter, which may explain their high tolerance to ammonium (NH4+) and ammonia (NH3). They come out to feed during high tide on various organisms such as bivalves, fish and, to a lesser extent, macroalgae. They are excellent swimmers, largely due to a pair of flattened legs that resemble paddles. However, in contrast to another portunid crab (''Scylla serrata''), they ...

Spanish Mackerel
Scomberomorini is a tribe of ray-finned saltwater bony fishes that is commonly known as the Spanish mackerels, seerfishes or seer fish. This fish closely resembles the King Mackerel. This tribe is a subset of the mackerel family (Scombridae) – a family that it shares with three sister tribes, the tunas, mackerels, and bonitos, and the butterfly kingfish. Scomberomorini comprises 21 species across three genera. They are pelagic fish, fast swimmers and predatory in nature, that fight vigorously when caught. Seer fishes are mainly caught using hooks and lines. Taxonomy The following cladogram shows the most likely evolutionary relationships between the Spanish mackerels and the tunas, mackerels, bonitos, and the butterfly kingfish. This tribe comprises 21 species in three genera: * ''Acanthocybium'' (Gill, 1862) ** '' A. solandri'' ( Cuvier, 1832), wahoo * ''Grammatorcynus'' (Gill, 1862) ** '' G. bicarinatus'' ( Quoy & Gaimard, 1825), shark mackerel ** '' G. bilineatus'' ( ...

Shrimp
Shrimp are crustaceans (a form of shellfish) with elongated bodies and a primarily swimming mode of locomotion – most commonly Caridea and Dendrobranchiata of the decapod order, although some crustaceans outside of this order are referred to as "shrimp". More narrow definitions may be restricted to Caridea, to smaller species of either group or to only the marine species. Under a broader definition, ''shrimp'' may be synonymous with prawn, covering stalk-eyed swimming crustaceans with long, narrow muscular tails (abdomens), long whiskers ( antennae), and slender legs. Any small crustacean which resembles a shrimp tends to be called one. They swim forward by paddling with swimmerets on the underside of their abdomens, although their escape response is typically repeated flicks with the tail driving them backwards very quickly. Crabs and lobsters have strong walking legs, whereas shrimp have thin, fragile legs which they use primarily for perching.Rudloe & Rudloe (2009 ...
