Zeidae
The Zeidae (named after Zeus, the supreme god of Greek mythology) are a family of large, showy, deep-bodied zeiform marine fish—the "true dories". Found in the Atlantic, Indian, and Pacific Oceans, the family contains just six species in two genera. All species are important and highly regarded food fish supporting commercial fisheries, and some—such as the John Dory (''Zeus faber'')—are enjoyed in large public aquaria. These fish are caught primarily by deep-sea trawling. Several other families have members sharing the common name 'dory', some of which—i.e., those of genera '' Capromimus'', '' Cyttomimus'', and '' Cyttus''—were once placed within the Zeidae. The first two genera are now found within the Zenionidae (or Zeniontidae), and the last genus has been given its own family, Cyttidae. Description All dories share the same roughly discoid, laterally compressed body plan. The head is large and sloping to concave in profile; the oblique mouth is ...

Mirror Dory
The mirror dory (''Zenopsis nebulosa'') is a dory of the family Zeidae, found in the southern Pacific Ocean at depths of between 30 and 800 m. Its length is up to 70 cm. The mirror dory has a high first dorsal fin containing 9 spiny rays, and about 27 soft rays in the second. The forward set of pelvic fin rays are very elongated. There are large flat spines on each side of the body at the base of the dorsal and anal fins. The scaleless body is a uniform silver, so bright as to be almost mirror-like, with an indistinct dark patch in the middle of each flank.

Zenopsis
''Zenopsis'' is a genus of dories, a group of marine fish. There are four extant species, but the genus is also known from fossils dating back to the Oligocene epoch. They largely resemble the better-known John Dory, and are typically found in relatively deep water, below normal scuba diving depth. Species There are currently four recognized recent species in this genus: * '' Zenopsis conchifer'' ( R. T. Lowe, 1852) (sometimes misspelledBailly, N.

Dory (fish)
The common name ''dory'' (from the Middle English ''dorre'', from the Middle French ''doree'', lit. "gilded one") is shared (officially and colloquially) by members of several different families of large-eyed, silvery, deep-bodied, laterally compressed, and roughly discoid marine fish. As well as resembling each other, dories are also similar in habit: most are deep-sea and demersal. Additionally, many species support commercial fisheries as food fish. Most dory families belong to the order Zeiformes, suborder Zeioidei: *The "true dories", family Zeidae (five species, including the well-known John Dory) *The zeniontids, family Zenionidae or Zeniontidae (seven species) *The "Australian dories", family Cyttidae (three species all within the genus '' Cyttus'') *The oreos, family Oreosomatidae (ten species) *The parazen family, Parazenidae (four species, including the rosy dory) Additionally, several species of spinyfin (family Diretmidae, order Beryciformes) have been given th ...

Zeiform
The Zeiformes are a small order of marine ray-finned fishes most notable for the dories, a group of common food fish. The order consists of about 33 species in seven families, mostly deep-sea types. Zeiform bodies are usually thin and deep. Mouths are large, with distensible jaws, and there is no orbitosphenoid. Pelvic fins have 5–10 soft rays and possibly a spine, 5–10 dorsal fin spines and up to 4 anal fin spines. They range in size from the dwarf dory ''(Macrurocyttus acanthopodus)'', at in length, to the Cape dory ''(Zeus capensis)'', which measures up to . The boarfishes (Caproidae) have been included in this order though they are currently included in the Perciformes.

Caudal Fin
Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish. They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as seen in sharks. Apart from the tail or caudal fin, fish fins have no direct connection with the spine and are supported only by muscles. Their principal function is to help the fish swim. Fins located in different places on the fish serve different purposes such as moving forward, turning, keeping an upright position or stopping. Most fish use fins when swimming, flying fish use pectoral fins for gliding, and frogfish use them for crawling. Fins can also be used for other purposes; male sharks and mosquitofish use a modified fin to deliver sperm, thresher sharks use their caudal fin to stun prey, reef stonefish have spines in their dorsal fins that inject venom, anglerfish use the first spine of their dorsal fin like a fishing rod to lu ...

Dorsal Fin
A dorsal fin is a fin located on the back of most marine and freshwater vertebrates within various taxa of the animal kingdom. Many species of animals possessing dorsal fins are not particularly closely related to each other, though through convergent evolution they have independently evolved external superficial fish-like body plans adapted to their marine environments, including most numerously fish, but also mammals such as cetaceans (whales, dolphins, and porpoises), and even extinct ancient marine reptiles such as various known species of ichthyosaurs. Most species have only one dorsal fin, but some have two or three. Wildlife biologists often use the distinctive nicks and wear patterns which develop on the dorsal fins of large cetaceans to identify individuals in the field. The bony or cartilaginous bones that support the base of the dorsal fin in fish are called ''pterygiophores''. Functions The main purpose of the dorsal fin is to stabilize the animal against rollin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spine (zoology)
In a zoological context, spines are hard, needle-like anatomical structures found in both vertebrate and invertebrate species. The spines of most spiny mammals are modified hairs, with a spongy center covered in a thick, hard layer of keratin and a sharp, sometimes barbed tip. Occurrence Mammals Spines in mammals include the prickles of hedgehogs and among rodents, the quills of both New World and Old World porcupines as well as the prickly fur of spiny mice, spiny pocket mice and spiny rats. They are also found on afrotherian tenrecs, marsupial spiny bandicoots and on echidnas, of the monotremes. An ancient synapsid, '' Dimetrodon'', had extremely long spines on its backbone that were joined together with a web of skin that formed a sail-like structure. Many mammalian species, like cats and fossas, also have penile spines. The Mesozoic eutriconodont mammal ''Spinolestes'' already displayed spines similar to those of modern spiny mice. Fish Spines are found in the rays o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aquarium
An aquarium (plural: ''aquariums'' or ''aquaria'') is a vivarium of any size having at least one transparent side in which aquatic plants or animals are kept and displayed. Fishkeepers use aquaria to keep fish, invertebrates, amphibians, aquatic reptiles, such as turtles, and aquatic plants. The term ''aquarium'', coined by English naturalist Philip Henry Gosse, combines the Latin root , meaning 'water', with the suffix , meaning 'a place for relating to'. The aquarium principle was fully developed in 1850 by the chemist Robert Warington, who explained that plants added to water in a container would give off enough oxygen to support animals, so long as the numbers of animals did not grow too large. The aquarium craze was launched in early Victorian England by Gosse, who created and stocked the first public aquarium at the London Zoo in 1853, and published the first manual, ''The Aquarium: An Unveiling of the Wonders of the Deep Sea'' in 1854.Katherine C.

Pelvic Fin
Pelvic fins or ventral fins are paired fins located on the ventral surface of fish. The paired pelvic fins are homologous to the hindlimbs of tetrapods. Structure and function Structure In actinopterygians, the pelvic fin consists of two endochondrally-derived bony girdles attached to bony radials. Dermal fin rays (lepidotrichia) are positioned distally from the radials. There are three pairs of muscles each on the dorsal and ventral side of the pelvic fin girdle that abduct and adduct the fin from the body. Pelvic fin structures can be extremely specialized in actinopterygians. Gobiids and lumpsuckers modify their pelvic fins into a sucker disk that allow them to adhere to the substrate or climb structures, such as waterfalls. In priapiumfish, males have modified their pelvic structures into a spiny copulatory device that grasps the female during mating.
