Abralia (Enigmoteuthis)
''Abralia'' is a genus of squid comprising around 20 species from the family Enoploteuthidae. They are small squid which can be found in the epipelagic to mesopelagic zones while some species are found in water with shallow substrates on steep slopes on the boundary of the mesopelagic zone. They are distinguished from other members of the Enoploteuthidae by not normally having large, black photophores at the tips of arms IV, although if these are present they are not covered in black chromatophores, and having fins which extend beyond their tail. The photophores of the integument are characteristicand are found in the three types . "Lensed" photophores are a blue color with a white ring, "simple" photophores are small and violet-colored and the "complex" photophores are surrounded by small green satellite points and have a green centre. The complex photophores will frequently appear to be blue depending on their physiological state. The integument also has small black chromat ...

Abralia Redfieldi
''Abralia redfieldi'' is a species of enoploteuthid cephalopod ranging across the Atlantic Ocean from the waters of Nova Scotia to Argentina in the west, to the waters of western Africa south to South Africa in the east. It has been caught at depths of 50–100 m at night, and is preyed upon by dwarf sperm whale The dwarf sperm whale (''Kogia sima'') is a sperm whale that inhabits temperate and tropical oceans worldwide, in particular continental shelves and slopes. It was first described by biologist Richard Owen in 1866, based on illustrations by n ...s. It is similar in appearance to the Pacific Ocean species, ''Abralia similis.''

Photophore
A photophore is a glandular organ that appears as luminous spots on various marine animals, including fish and cephalopods. The organ can be simple, or as complex as the human eye; equipped with lenses, shutters, color filters and reflectors, however unlike an eye it is optimized to produce light, not absorb it. The bioluminescence can variously be produced from compounds during the digestion of prey, from specialized mitochondrial cells in the organism called photocytes ("light producing" cells), or, similarly, associated with symbiotic bacteria in the organism that are cultured. The character of photophores is important in the identification of deep sea fishes. Photophores on fish are used for attracting food or for camouflage from predators by counter-illumination. Photophores are found on some cephalopods including the firefly squid, which can create impressive light displays, as well as numerous other deep sea organisms such as the pocket shark Mollisquama mississippien ...

Georg Grimpe
Johann Georg Grimpe (16 February 1889, in Leipzig – 22 January 1936) was a German zoologist and malacologist. He studied zoology and comparative anatomy at the University of Leipzig, where under the influence of Carl Chun (1852–1914), he focused his energies towards research of marine fauna, especially cuttlefish. He conducted studies at marine biology stations in Naples, Villefranche-sur-Mer, Helgoland and Monaco. In 1912 he obtained his doctorate with a dissertation on the vascular system of Octopoda.Grimpe, Johann Georg @ NDB/ADB Deutsche Biographie After graduation, he worked as an assistant at the , being tasked with scientific design issues concerning its |

Madoka Sasaki
was a Japanese zoologist, who is known for his work on the cephalopods of Japan, as well as other groups such as salamanders. Sasaki was Professor of Zoology in the Fishery Department of the College of Agriculture at Tohoku Imperial University, Sapporo, Japan. Sasaki died in 1927 and his major work ''A monograph of the dibranchiate cephalopods of the Japanese and adjacent waters'' was published posthumously in 1929, and was based largely on his studies of the cephalopod collections of the Zoology Department of the "Tokyo University Museum", many of which he collected himself. The species ''Sebastodes sasakii'', ''Octopus sasakii'' and ''Sepia sasakii Sepia may refer to: Biology * ''Sepia'' (genus), a genus of cuttlefish Color * Sepia (color), a reddish-brown color * Sepia tone, a photography technique Music * ''Sepia'', a 2001 album by Coco Mbassi * ''Sepia'' (album) by Yu Takahashi * "S ...'' are among the taxa that bear names that honour Sasaki.

Toothed Whales
The toothed whales (also called odontocetes, systematic name Odontoceti) are a parvorder of cetaceans that includes dolphins, porpoises, and all other whales possessing teeth, such as the beaked whales and sperm whales. Seventy-three species of toothed whales are described. They are one of two living groups of cetaceans, the other being the baleen whales (Mysticeti), which have baleen instead of teeth. The two groups are thought to have diverged around 34 million years ago (mya). Toothed whales range in size from the and vaquita to the and sperm whale. Several species of odontocetes exhibit sexual dimorphism, in that there are size or other morphological differences between females and males. They have streamlined bodies and two limbs that are modified into flippers. Some can travel at up to 20 knots. Odontocetes have conical teeth designed for catching fish or squid. They have well-developed hearing, that is well adapted for both air and water, so much so that some can surviv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Billfish
The term billfish refers to a group of saltwater predatory fish characterised by prominent pointed bills (rostra), and by their large size; some are longer than . Extant billfish include sailfish and marlin, which make up the family Istiophoridae; and swordfish, sole member of the family Xiphiidae. They are apex predators which feed on a wide variety of smaller fish, crustaceans and cephalopods. These two families are sometimes classified as belonging to the order Istiophoriformes, a group which originated around 71 million years ago in the Late Cretaceous, with the two families diverging around 15 million years ago in the Late Miocene. However, they are also classified as being closely related to the mackerels and tuna within the suborder Scombroidei of the order Perciformes. However, the 5th edition of the ''Fishes of the World'' does recognise the Istiophoriformes as a valid order, albeit including the Sphyraenidae, the barracudas. Billfish are pelagic and highly migrato ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tuna
A tuna is a saltwater fish that belongs to the tribe Thunnini, a subgrouping of the Scombridae (mackerel) family. The Thunnini comprise 15 species across five genera, the sizes of which vary greatly, ranging from the bullet tuna (max length: , weight: ) up to the Atlantic bluefin tuna (max length: , weight: ), which averages and is believed to live up to 50 years. Tuna, opah and mackerel sharks are the only species of fish that can maintain a body temperature higher than that of the surrounding water. An active and agile predator, the tuna has a sleek, streamlined body, and is among the fastest-swimming pelagic fish – the yellowfin tuna, for example, is capable of speeds of up to . Greatly inflated speeds can be found in early scientific reports and are still widely reported in the popular literature. Found in warm seas, the tuna is commercially fished extensively as a food fish, and is popular as a bluewater game fish. As a result of overfishing, some tuna species, s ...

Subgenus
In biology, a subgenus (plural: subgenera) is a taxonomic rank directly below genus. In the International Code of Zoological Nomenclature, a subgeneric name can be used independently or included in a species name, in parentheses, placed between the generic name and the specific epithet: e.g. the tiger cowry of the Indo-Pacific, ''Cypraea'' (''Cypraea'') ''tigris'' Linnaeus, which belongs to the subgenus ''Cypraea'' of the genus ''Cypraea''. However, it is not mandatory, or even customary, when giving the name of a species, to include the subgeneric name. In the International Code of Nomenclature for algae, fungi, and plants (ICNafp), the subgenus is one of the possible subdivisions of a genus. There is no limit to the number of divisions that are permitted within a genus by adding the prefix "sub-" or in other ways as long as no confusion can result. Article 4 The secondary ranks of section and series are subordinate to subgenus. An example is ''Banksia'' subg. ''Isostylis'', ...
