Lantern Shark
''Etmopterus'' is a genus of lantern sharks in the squaliform family Etmopteridae. They are found in deep sea ecosystems of the Atlantic, Indian and Pacific Oceans. Ecology A number of species in this genus function as host to the specialized parasitic barnacle ''Anelasma squalicola'', which embeds itself into the skin of the shark and extracts nutrients from its bloodstream. Species There are currently 45 recognized species in this genus: * ''Etmopterus alphus'' Ebert, Straube, Leslie & Weigmann, 2016 (whitecheek lanternshark) * ''Etmopterus baxteri'' Garrick, 1957 (New Zealand lanternshark) * ''Etmopterus benchleyi'' Vásquez, Ebert & D. J. Long, 2015 (ninja lanternshark) * ''Etmopterus bigelowi'' Shirai & Tachikawa, 1993 (blurred lanternshark) * ''Etmopterus brachyurus'' H. M. Smith & Radcliffe, 1912 (short-tail lanternshark) * '' Etmopterus brosei'' Ebert, Leslie & Weigmann, 2021 * '' Etmopterus bullisi'' Bigelow & Schroeder, 1957 * '' Etmopterus burgessi'' S ...

Middle Eocene
The Eocene ( ) Epoch is a geological epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period in the modern Cenozoic Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', "dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope 13C in the atmosphere was exceptionally low in comparison with the more common isotope 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Siberia and in what is now Chesapeake Bay. As with other geologic periods, the strata that define the start and end of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

In the Books of Samuel, he is described as a young shepherd and harpist who gains fame by slaying Goliath, a champion of the Philistines, in southern Canaan. David becomes a favourite of Saul, the first king of Israel; he also forges a notably close friendship with Jonathan, a son of Saul. However, under the paranoia that David is seeking to usurp the throne, Saul attempts to kill David, forcing the latter to go into hiding and effectively operate as a fugitive for several years. After Saul and Jonathan are both killed in battle against the Philistines, a 30-year-old David is anointed king over all of Israel and Judah. Following his rise to power, David ...

Etmopterus Bigelowi
The blurred lanternshark (''Etmopterus bigelowi'') is a little-known species of dogfish shark in the family Etmopteridae, found around the world in benthic and pelagic habitats from a depth of to over down. This shark forms the '' E. pusillus'' species group with the smooth lanternshark, which are distinguished from other members of its family by having irregularly arranged, flat-topped dermal denticles that give them a "smooth" appearance. Both species are slender-bodied with long heads, two dorsal fins bearing spines, no anal fins, and light-emitting photophores. The blurred lanternshark is larger, reaching or more in length. This species feeds on small squid, fishes, and fish eggs, and is ovoviviparous. It has been assessed as of Least Concern by the International Union for Conservation of Nature, because of its wide distribution and lack of threat from fishing pressure. Taxonomy and phylogeny Japanese ichthyologists Shigeru Shirai and Hiroyuki Tachikawa described the blurr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Roosevelt in 1939, Douglas was confirmed at the age of 40, becoming one of the youngest justices appointed to the court. After an itinerant childhood, Douglas attended Whitman College on a scholarship. He graduated from Columbia Law School in 1925 and joined the Yale Law School faculty.

Jack Garrick
John Andrew Frank "Jack" Garrick (1928 – August 30, 2018) was a New Zealand ichthyologist. He specialized in elasmobranchs and published many books and articles about shark and ray biology. In 1982, he published a thorough taxonomy on sharks of the genus ''Carcharhinus'', where he identified the smoothtooth blacktip shark as a new species. He is the species authority for several types of sharks, including the New Zealand lanternshark. Garrick was a zoology professor at Victoria University of Wellington, appointed to a personal chair in 1971. He had a primary interest in the taxonomy of sharks and rays, and carried out the first exploratory deep-sea sampling using specially adapted cone nets, baited traps, and longlines, regularly to depths greater than 2000 m. Many new and rare species were obtained by use of these innovative techniques. He was responsible for the notable discovery of the first New Zealand specimens of orange roughy in 1957 (which subsequently formed the basis ...
