Deveximentum
''Deveximentum'' is a genus of ponyfishes native to the Indian Ocean and the western Pacific Ocean. Genus name The genus had been once named as ''Secutor'' but ''Secutor'' was coined by Gistel in 1848 with Peter Forsskål, Forsskål’s ''Scombrops equula'' as its type species, this being a Synonym (taxonomy), synonym for ''Leiognathus equulus''. In 1904 Fowler created the genus ''Deveximentum'' with Bloch’s ''Zeus insidiator'' as its type species. Catalog of Fishes states that as the type species for ''Secutor'' is synonymous with ''L. equulus'' then ''Secutor'' is a synonym of ''Leiognathus'' and prefers Fowler’s ''Deveximentum''. Species There are currently eight recognized species in this genus: * ''Deveximentum hanedai'' (Kenji Mochizuki, Mochizuki & Masayoshi Hayashi, Hayashi, 1989) * ''Deveximentum indicium'' (Supap Monkolprasit, Monkolprasit, 1973) * ''Deveximentum insidiator'' (Marcus Elieser Bloch, Bloch, 1787) (Pugnose ponyfish) * ''Deveximentum interruptum'' (Ac ...

Deveximentum Insidiator
''Deveximentum insidiator'' or previously ''Secutor insidiator'', the pugnose ponyfish or barred ponyfish, is a species of ray-finned fish, a ponyfish in the family Leiognathidae. The barred ponyfish's mineralized skeleton contains apatite and the mineralized tissue contains hydroxylapatite. They have bare heads with nuchal spines and their bodies are a distinctive, reflective silver, frequently imitated by fishermen using silver lures. They have a protracted mouth pointing upward and the tip of the maxilla reaches well below the level of the lower margin of the eye. Barred ponyfish feed on zooplankton, including larval fishes and crustaceans. Body depth is twice or slightly more than standard length, which measures 11.3 cm from the tip of the snout to last vertebra. The lateral line ends before the dorsal fin. Classification/names ''Secutor insidiator'' was first formally described in 1781 as ''Zeus insidiator'' by Marcus Elieser Bloch with the type locality given as Surat in I ...

Deveximentum Hanedai
''Deveximentum hanedai'' is a species of marine ray-finned fish, a ponyfish from the family Leiognathidae. It isnative to the Indian and Pacific ocean waters around the countries of Thailand, Indonesia and Malaysia. It can be found in marine and brackish waters. Size This species can reach a length of SL. Etymology The specific name honours Yata Haneda (1907-1995), a Japanese biologist who studied bioluminescent Bioluminescence is the emission of light during a chemiluminescence reaction by living organisms. Bioluminescence occurs in multifarious organisms ranging from marine vertebrates and invertebrates, as well as in some fungi, microorganisms inc ... organisms, including ponyfishes.

Ponyfish
Leiognathidae, the ponyfishes, slipmouths or slimys / slimies, are a small family of fishes in the order Perciformes. They inhabit marine and brackish waters in the Indian and West Pacific Oceans. They can be used in the preparation of ''bagoong''. Characteristics Ponyfishes are small and laterally compressed in shape, with a bland, silvery colouration. They are distinguished by highly extensible mouths, and the presence of a mechanism for locking the spines in the dorsal and anal fins. They also possess a highly integrated light organ in their throats that houses symbiotic bioluminescent bacteria that project light through the animal's underside. Typically, the harbored bacterium is only ''Photobacterium leiognathi'', but in the two ponyfish species ''Photopectoralis panayensis'' and ''Photopectoralis bindus'', ''Photobacterium mandapamensis'' is also present. Two of the most widely studied uses for luminescence in ponyfish are camouflage by ventral counterillumination and spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bioluminescent Fish
Bioluminescence is the emission of light during a chemiluminescence reaction by living organisms. Bioluminescence occurs in multifarious organisms ranging from marine vertebrates and invertebrates, as well as in some fungi, microorganisms including some bioluminescent bacteria, dinoflagellates and terrestrial arthropods such as fireflies. In some animals, the light is bacteriogenic, produced by symbiotic bacteria such as those from the genus '' Vibrio''; in others, it is autogenic, produced by the animals themselves. In most cases, the principal chemical reaction in bioluminescence involves the reaction of a substrate called luciferin and an enzyme, called luciferase. Because these are generic names, luciferins and luciferases are often distinguished by the species or group, e.g. firefly luciferin or cypridina luciferin. In all characterized cases, the enzyme catalyzes the oxidation of the luciferin resulting in excited state oxyluciferin, which is the light emitter of ...

Francis Buchanan-Hamilton
Francis Buchanan (15 February 1762 – 15 June 1829), later known as Francis Hamilton but often referred to as Francis Buchanan-Hamilton, was a Scottish surgeon, surveyor and botanist who made significant contributions as a geographer and zoologist while living in India. He did not assume the name of Hamilton until three years after his retirement from India. The standard botanical author abbreviation Buch.-Ham. is applied to plants and animals he described, though today the form "Hamilton, 1822" is more usually seen in ichthyology and is preferred by Fishbase. Early life Francis Buchanan was born at Bardowie, Callander, Perthshire where Elizabeth, his mother, lived on the estate of Branziet; his father Thomas, a physician, came in Stirling, Spittal and claimed the chiefdom of the name of Clan Buchanan, Buchanan and owned the Leny estate. Francis Buchanan matriculated in 1774 and received an MA in 1779. As he had three older brothers, he had to earn a living from a profession, ...
