Lamprey
Lampreys (sometimes inaccurately called lamprey eels) are an ancient extant lineage of jawless fish of the order Petromyzontiformes , placed in the superclass Cyclostomata. The adult lamprey may be characterized by a toothed, funnel-like sucking mouth. The common name "lamprey" is probably derived from Latin , which may mean "stone licker" ( "to lick" + "stone"), though the etymology is uncertain. ''Lamprey'' is sometimes seen for the plural form. There are about 38 known extant species of lampreys and five known extinct species. Parasitic carnivorous species are the most well-known, and feed by boring into the flesh of other fish to suck their blood; but only 18 species of lampreys engage in this micropredatory lifestyle. Of the 18 carnivorous species, nine migrate from saltwater to freshwater to breed (some of them also have freshwater populations), and nine live exclusively in freshwater. All non-carnivorous forms are freshwater species. Adults of the non-carnivorous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Lamprey
The lake lamprey, ''Entosphenus macrostomus'', also known as the Vancouver lamprey or Cowichan lamprey, a recent derivative of the Pacific lamprey, is a species of freshwater lamprey endemic to two North American lakes: Lake Cowichan and Mesachie Lake in Vancouver Island, Canada. The lamprey was originally called the Vancouver Island lamprey, until an error in filing shortened it to the Vancouver lamprey. The alternate common name of "Cowichan lamprey" was coined and promoted by the species' describer, Dr. Dick Beamish, who originally identified the species in the 1980s. Description An adult lake lamprey is dark blue or dark brown with a lighter belly, and the body is 11.8-27.3 cm in length. The lamprey's disc-like mouth is filled with sharp teeth. The Vancouver lamprey has eyes on the top of its head, two dorsal fins, a caudal fin, and an anal fin. Distribution and habitat The lake lamprey is found only in the Cowichan and Mesachie Lakes on Vancouver Island, and is not ...

Pacific Lamprey
The Pacific lamprey (''Entosphenus tridentatus'') is an anadromous parasitic lamprey from the Pacific Coast of North America and Asia. It is a member of the Petromyzontidae family. The Pacific lamprey is also known as the three-tooth lamprey and tridentate lamprey. Description Pacific lampreys grow to about as adults. They are anadromous and semelparous. They have slender, elongated bodies with two dorsal fins arising far back on the body. The anal fins are rudimentary and the lower lobe of the caudal fin is larger than the upper lobe and both lobes are continuous with the dorsal fin and the anal fin. Adults living in the sea are a bluish-black or greenish colour above and pale below, but those in fresh water are brown. This species is distinguished by having three (or occasionally two) sharp teeth on the supraoral bar above the mouth and three sharp points on each lateral plate. The Pacific lamprey are often found at sea or often far offshore. At sea, depth: near surface to 1, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kern Brook Lamprey
The Kern brook lamprey (''Lampetra hubbsi'') is a species of lamprey in the Petromyzontidae family endemic to the United States. It is found on the east side of San Joaquin Valley, in lower Merced, Kaweah, Kings, and San Joaquin rivers in California. It can grow to up to around 14 centimeters, and is characterized by its grayish brown and white coloring, and black spots on its fins. Description ''L. hubbsi'' is similar to other lampreys in that it has a thin eel body. Some of the morphological characteristics separating ''L. hubbsi'' from other lamprey species include SO lamina 2 cusps; 4 inner laterals unicuspid; IO lamina 5 cusps; posterials about 10 (unicuspid); velar tentacles 3; reduced number of myomeres. Not much is known about the biology of these lampreys. Classification Lamprey taxonomy can prove to be difficult because there are few morphological differences that can be observed. ''L. hubbsi'' was originally under the subgenus ''Entosphenus''. The genus ''Lampetra'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miller Lake Lamprey
The Miller Lake lamprey (''Entosphenus minimus'') is a species of lamprey in the Petromyzontidae family endemic to the United States. Its natural habitat is the Miller Lake drainage in the state of Oregon. This species is of special interest because it has an extremely limited distribution, with all known animals contained within a single small drainage system and it is the smallest known parasitic lamprey in the world. The Miller lake lamprey was presumed extinct in 1958, after state fishery managers attempted to eradicate the lamprey from the lake because it was feeding on the introduced trout.Miller, R. R., J. D. Williams, and J. E. Williams. 1989. Extinctions of North American Fishes During the Past Century. Fisheries 14:22-38. The known larval streams for this lamprey were treated with lampricide and a barrier was erected to prevent adults from entering to spawn. The Miller Lake lamprey was presumed to be extinct until 1992, when it was collected again. Continued collection ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

John Richardson (naturalist)
Sir John Richardson Royal Society of London, FRS FRSE (5 November 1787 – 5 June 1865) was a Scotland, Scottish naval surgeon, natural history, naturalist and Arctic explorer. Life Richardson was born at Nith Place in Dumfries the son of Gabriel Richardson, Provost of Dumfries, and his wife, Anne Mundell. He was educated at Dumfries Grammar School. He was then apprenticed to his maternal uncle, Dr James Mundell, a surgeon in Dumfries. He studied medicine at Edinburgh University, and became a surgeon in the navy in 1807. He traveled with John Franklin in search of the Northwest Passage on the Coppermine Expedition of 1819–1822. Richardson wrote the sections on geology, botany and ichthyology for the official account of the expedition. Franklin and Richardson returned to Canada in 1825 and went overland by fur trade routes to the mouth of the Mackenzie River. Franklin was to go as far west as possible and Richardson was to go east to the mouth of the Coppermine River. These ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
