Bathynomus Brucei
''Bathynomus brucei'' is a species of giant isopod first described in 2006. It was first located off of the coast of Australia, east of Flynn reef, though the range extends from waters of south-east of Asia to waters around the north of Australia. ''B. brucei'' is the largest 'giant' member of '' Bathynomus'', a specimen collected 400 metres below sea level measuring long. Members of the larger 'supergiant' group of ''Bathynomus'' species such as ''B. giganteus'' and '' B. kensleyi'' are known to grow to lengths of almost . Description As with all other members of ''Bathynomus'', ''B. brucei'' has seven pairs of pereopods and an exoskeleton composed of overlapping segments, the first segment of which is fused to the head. ''B. brucei'' is roughly twice as long as it is wide. It has nine pleotelsonic spines along the distal edge of the central tail fin (the telson The telson () is the hindmost division of the body of an arthropod. Depending on the definition, the telson ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Giant Isopod
A giant isopod is any of the almost 20 species of large isopods in the genus ''Bathynomus''. They are abundant in the cold, deep waters of the Atlantic, Pacific, and Indian Oceans.Lowry, J. K. and Dempsey, K. (2006). ''The giant deep-sea scavenger genus Bathynomus (Crustacea, Isopoda, Cirolanidae) in the Indo-West Pacific.'' In: Richer de Forges, B. and Justone, J.-L. (eds.), Résultats des Compagnes Musortom, vol. 24. Mémoires du Muséum National d’Histoire Naturalle, Tome 193: 163–192. '' Bathynomus giganteus'', the species upon which the generitype is based, is often considered the largest isopod in the world, though other comparably poorly known species of ''Bathynomus'' may reach a similar size (e.g., ''B. kensleyi''). The giant isopods are noted for their resemblance to the much smaller common woodlouse (pill bug), to which they are related. French zoologist Alphonse Milne-Edwards was the first to describe the genus in 1879 after his colleague Alexander Agassiz coll ...

Bathynomus Giganteus
''Bathynomus giganteus'' is a species of aquatic crustacean, of the order Isopoda. It is a member of the giant isopods (''Bathynomus''), and as such it is related—albeit distantly—to shrimps and crabs. It was the first '' Bathynomus'' species ever documented and was described in 1879 by French zoologist Alphonse Milne Edwards after the isopod was found in fishermen's nets off the coast of the Dry Tortugas in the Gulf of Mexico. The ''Bathynomus'' genus is benthic and abundant in cold waters with a depth of 310–2140 m in the West-Atlantic, including the Gulf of Mexico and the Caribbean. It was the first species of ''Bathynomus'' to be described and historically it was reported from other oceans, but these are now recognized as other closely related species. The unusually large size of ''Bathynomus'' has been attributed to an effect called deep-sea gigantism, where invertebrates living in cold deep waters tend to grow larger and have longer lifespans.

Telson
The telson () is the hindmost division of the body of an arthropod. Depending on the definition, the telson is either considered to be the final segment (biology), segment of the arthropod body, or an additional division that is not a true segment on account of not arising in the embryo from teloblast areas as other segments. It never carries any appendages, but a forked "tail" called the caudal furca may be present. The shape and composition of the telson differs between arthropod groups. Crustaceans In lobsters, Caridea, shrimp and other Decapoda, decapods, the telson, along with the uropods, forms the tail fan. This is used as a paddle in the caridoid escape reaction ("lobstering"), whereby an alarmed animal rapidly flexes its tail, causing it to dart backwards. Krill can reach speeds of over 60 cm per second by this means. The Induction period, trigger time to optical stimulus (physiology), stimulus is, in spite of the low temperatures, only 55 milliseconds. In th ...

Cymothoida
Cymothoida is a suborder of Isopoda, isopod crustaceans with a mostly Carnivore, carnivorous or Parasite, parasitic lifestyle. It contains more than 2,700 described species in four Taxonomic rank#Ranks in zoology, superfamilies. Members of the suborder are characterised by their specialised mouthparts which include a mandible with a tooth-like process which is adapted for cutting or slicing. Classification Cymothoida contains these superfamilies and families: *Superfamily Anthuroidea Leach, 1814 **Antheluridae Poore & Lew Ton, 1988 **Anthuridae Leach, 1814 **Expanathuridae Poore, 2001 **Hyssuridae Wägele, 1981 **Leptanthuridae Poore, 2001 **Paranthuridae Menzies & Glynn, 1968 *Superfamily Cymothooidea Leach, 1814 **Aegidae White, 1850 **Anuropidae Stebbing, 1893 **Barybrotidae Hansen, 1890 **Cirolanidae Dana, 1852 **Corallanidae Hansen, 1890 **Cymothoidae Leach, 1818 **Gnathiidae Leach, 1814 **Protognathiidae Wägele & Brandt, 1988 **Tridentellidae Bruce, 1984 *Infraorder Epica ...

Crustaceans Described In 2006
Crustaceans (from Latin meaning: "those with shells" or "crusted ones") are invertebrate animals that constitute one group of arthropods that are traditionally a part of the subphylum Crustacea (), a large, diverse group of mainly aquatic arthropods including decapods (shrimps, prawns, crabs, lobsters and crayfish), seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, opossum shrimps, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods (insects and entognathans) emerged deep in the Crustacean group, with the completed pan-group referred to as Pancrustacea. The three classes Cephalocarida, Branchiopoda and Remipedia are more closely related to the hexapods than they are to any of the other crustaceans (oligostracans and multicrustaceans). The 67,000 described species range in size from ''Stygotantulus stocki'' at , to the Japanese spider crab with a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fauna Of Southeast Asia
Southeast Asia is the geographical United Nations geoscheme for Asia#South-eastern Asia, southeastern region of Asia, consisting of the regions that are situated south of China, east of the Indian subcontinent, and northwest of the Mainland Australia, Australian mainland, which is part of Oceania. Southeast Asia is bordered to the north by East Asia, to the west by South Asia and the Bay of Bengal, to the east by Oceania and the Pacific Ocean, and to the south by Australia (continent), Australia and the Indian Ocean. Apart from the British Indian Ocean Territory and two out of Atolls of the Maldives, 26 atolls of the Maldives in South Asia, Maritime Southeast Asia is the only other subregion of Asia that lies partly within the Southern Hemisphere. Mainland Southeast Asia is entirely in the Northern Hemisphere. Timor-Leste and the southern portion of Indonesia are the parts of Southeast Asia that lie south of the equator.
