Ammodytes Americanus
''Ammodytes americanus'', also known as American sand lance, American sand eel, and sand launce, is a small fish in the family Ammodytidae. First described by James Ellsworth De Kay in 1842, it is widespread in the western North Atlantic. The fish typically travel in large schools, spending most of their time relatively near the water surface. It feeds primarily on plankton, though it is known to take small clams and snails from the sea floor, presumably when plankton is scarce. Towards dusk, schools of ''A. americanus'' bury themselves in coarse sand, typically from below the sand's surface close to the water's edge; they avoid rocky areas. They do this to avoid being detected by night-hunting species such as bluefish and stripers. ''Ammodytes americanus'' is an important prey item for many species of fish, whales and birds. Breeding roseate terns, a federally endangered species in the United States, feed their chicks almost exclusively on the species. Description Like all ...

Ammodytes Marinus
Raitt's sand eel (''Ammodytes marinus''), is a small semi-pelagic ray-finned fish found in the North Atlantic Ocean. The Raitt's sand eel is member of the family Ammodytidae which includes all 31 species of sand eels, often referred to as sand lances. Contrary to their name sand eels, including Raitt's sand eel, are not true eels and instead belong to the order of "weever-like" fishes, the Trachiniformes. Description The Raitt's sand eel is a small elongated fish that is usually about 20 cm long. The maximum length reported for this species of sand eel is 25 cm. They are silver all over with darker scales on their dorsal (anatomy), dorsal side. Raitt's sand eels have a short tail fin that is deeply forked. They have a long and low dorsal fin that is twice as long as the tail fin and runs along almost the entire body. The scales on their underside are arranged randomly instead of in a distinct pattern as in many other fish. The Raitt's sand eel has a pointed jaw where th ...

Sand Lance
A sand lance or sandlance is a ray-finned fish belonging to the family Ammodytidae. Several species of sand lances are commonly known as " sand eels", though they are not related to true eels. Another variant name is launce, and all names of the fish are references to its slender body and pointed snout. The family name (and genus name, '' Ammodytes'') means "sand burrower", which describes the sand lance's habit of burrowing into sand to avoid tidal currents. Sand lances are most commonly encountered by fishermen in the North Pacific and North Atlantic, but are found in oceans throughout the world. These fish do not have pelvic fins and do not develop swim bladders, staying true to their bottom-dwelling habit as adults. Both adult and larval sea lances primarily feed on copepods. Larval forms of this fish are perhaps the most abundant of all fish larvae in areas such as the northwest Atlantic, serving as a major food item for cod, salmon, whales and other commercially impo ...

Ammodytes Tobianus
The lesser sand eel or sand lance (''Ammodytes tobianus'') is a species of fish in the sand lance family Ammodytidae. It is an elongated cylindrical fish which may be up to long. Description The body of the lesser sand eel has an elongated shape with a rounded cross section. The head is also elongated and pointed, and the sharp prominent lower jaw projects further than the upper jaw. When the mouth is opened, the two jaws form a tube through which food is sucked in. The top of the fish's mouth lacks teeth. The scales of the belly make a chevron pattern. The dorsal fin is long and ribbon-like, the pectoral fins are small and low set, and there are no pelvic fins. The caudal fin is bifurcated in shape. The skin color is greenish yellow on the back, yellowish on the upper sides, and a mixture of a brilliant silver on the lower sides and belly. This fish can be distinguished from the greater sand eel by its smaller size (less than ) and the fact that the origin of the long dorsal f ...

James Wilder Orr
James Wilder Orr (born Huntington, New York, July 19, 1958) is an American fisheries biologist, ichthyologist, and systematist best known for his studies of skates, rockfishes, snailfishes, and flatfishes. He has described 32 new species and two new genera of fishes, and is the author or co-author of more than 130 scientific and popular articles, including three books. His work has focused primarily on the phylogenetic relationships, zoogeography, reproductive biology, and behavior of marine teleosts, particularly deep-water benthic taxa. He has spent most of his career at the Alaska Fisheries Science Center, National Marine Fisheries Service (NMFS), in Seattle, as a Research Fisheries Biologist. At the same time, he has served as an Affiliate Professor at the School of Aquatic and Fishery Sciences, and Affiliate Curator of Fishes at the Burke Museum of Natural History and Culture, University of Washington, Seattle.

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] |
