Synodus Foetens
The inshore lizardfish (''Synodus foetens'') is a member of the family Synodontidae found in the western Atlantic. According to the IUCN red list for endangered species, the inshore lizard fish "has most recently been assessed for the IUCN Red List of Threatened Species in 2013. Synodus foetens is listed as Least Concern" (Russell et al., 2015). Description The inshore lizardfish has a maximum length recorded of about 50 cm but lengths around 40 cm are more common. Their lifespan can be up to nine years. The body of this species is elongated, similar to a cigar.Harry, Shivrani. "Synodus foetens (Inshore Lizardfish)."

Carl Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was the son of a curate and was born in Råshult, in the countryside of Småland, southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synodontidae
The Synodontidae or lizardfishes(or typical lizardfish to distinguish them from the Bathysauridae and Pseudotrichonotidae) are benthic (bottom-dwelling) marine and estuarine bony fishes that belong to the aulopiform fish order, a diverse group of marine ray-finned fish consisting of some 15 extant and several prehistoric families. They are found in tropical and subtropical marine waters throughout the world. Lizardfishes are generally small, although the largest species measures about in length. They have slender, somewhat cylindrical bodies, and heads that superficially resemble those of lizards. The dorsal fin is located in the middle of the back, and accompanied by a small adipose fin placed closer to the tail. They have mouths full of sharp teeth, even on the tongue. Lizardfishes are benthic animals that live in shallow coastal waters; even the deepest-dwelling species of lizardfish live in waters no more than deep. Some species in the subfamily Harpadontinae live in b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Locomotion
Fish locomotion is the various types of animal locomotion used by fish, principally by swimming. This is achieved in different groups of fish by a variety of mechanisms of propulsion, most often by wave-like lateral flexions of the fish's body and tail in the water, and in various specialised fish by motions of the fins. The major forms of locomotion in fish are: * Anguilliform, in which a wave passes evenly along a long slender body; * Sub-carangiform, in which the wave increases quickly in amplitude towards the tail; * Carangiform, in which the wave is concentrated near the tail, which oscillates rapidly; * Thunniform, rapid swimming with a large powerful crescent-shaped tail; and * Ostraciiform, with almost no oscillation except of the tail fin. More specialized fish include movement by pectoral fins with a mainly stiff body, opposed sculling with dorsal and anal fins, as in the sunfish; and movement by propagating a wave along the long fins with a motionless body, as in the ...

Ureaplasma Parvum
''Ureaplasma parvum'' is a species of ''Ureaplasma'', a genus of bacteria belonging to the family Mycoplasmataceae. ''Ureaplasma parvum'' was formerly known as ''Ureaplasma urealyticum biovar'' 1. ''Ureaplasma parvum'' has been identified as being a commensal in the female reproductive tract as part of the microbiome in healthy women of reproductive age. Classification ''Ureaplasma spp''. are one of the smallest known clonal bacteria. They are closely related to mycoplasmas as they lack a peptidoglycan cell wall, metabolize cholesterol, and require urea for ATP synthesis. The Ureaplasma genus has 14 serotypes that are classified based on the 16S rRNA gene, the urease gene, and the multiple-banded antigen (MBA) gene. ''U. parvum'' has four serotypes (-1, -3, -6, -14) that were differentiated by variations in the MBA gene, a Ureaplasma surface antigen protein. Although ''U. parvum'' is known to be a commensal microorganism within healthy humans, its ability to become pathogenic m ...

Longfin Inshore Squid
The longfin inshore squid (''Doryteuthis pealeii'') is a species of squid of the family Loliginidae. Description This species of squid is often seen with a reddish hue, but like many types of squid can manipulate its color, varying from a deep red to a soft pink. The dorsal mantle length of some males can reach up to 50 cm, although most squid commercially harvested are smaller than 30 cm long. This species exhibits sexual dimorphism, with most males growing faster and reaching larger sizes than females. Distribution The longfin inshore squid is found in the North Atlantic, schooling in continental shelf and slope waters from Newfoundland to the Gulf of Venezuela. It is commercially exploited, especially in the range from the Southern Georges Bank to Cape Hatteras. The population makes seasonal migrations that appear to be related to bottom water temperatures; they move offshore during late autumn to overwinter along the edge of the continental shelf and return ins ...

Pelagic Zone
The pelagic zone consists of the water column of the open ocean and can be further divided into regions by depth. The word ''pelagic'' is derived . The pelagic zone can be thought of as an imaginary cylinder or water column between the surface of the sea and the bottom. Conditions in the water column change with depth: pressure increases; temperature and light decrease; salinity, oxygen, micronutrients (such as iron, magnesium and calcium) all change. In a manner analogous to stratification in the Earth's atmosphere, the water column can be divided vertically into up to five different layers (illustrated in the diagram), with the number of layers depending on the depth of the water. Marine life is affected by bathymetry (underwater topography) such as the seafloor, shoreline, or a submarine seamount, as well as by proximity to the boundary between the ocean and the atmosphere at the ocean surface, which brings light for photosynthesis, predation from above, and wind sti ...

Benthic Zone
The benthic zone is the ecological region at the lowest level of a body of water such as an ocean, lake, or stream, including the sediment surface and some sub-surface layers. The name comes from the Ancient Greek word (), meaning "the depths". Organisms living in this zone are called benthos and include microorganisms (e.g., bacteria and Fungus, fungi) as well as larger invertebrates, such as crustaceans and polychaetes. Organisms here, known as bottom dwellers, generally live in close relationship with the substrate and many are permanently attached to the bottom. The benthic boundary layer, which includes the bottom layer of water and the uppermost layer of sediment directly influenced by the overlying water, is an integral part of the benthic zone, as it greatly influences the biological activity that takes place there. Examples of contact soil layers include sand bottoms, rocky outcrops, coral, and bay mud. Description Oceans The benthic region of the ocean begins at t ...

Fish Of The Eastern United States
A fish (: fish or fishes) is an aquatic, anamniotic, gill-bearing vertebrate animal with swimming fins and a hard skull, but lacking limbs with digits. Fish can be grouped into the more basal jawless fish and the more common jawed fish, the latter including all living cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are cold-blooded, their body temperature varying with the surrounding water, though some large active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communicate acoustically with each other, such as during courtship displays. The study of fish is known as ichthyology. The earliest fish appeared during the Cambrian as small filter feeders; they continued to evolve through the Paleozoic, diversifying into many forms. The earliest fish wi ...
