Oarfish
Oarfish are large and extremely long pelagic lampriform fish belonging to the small family (biology), family Regalecidae. Found in areas spanning from Temperate climate, temperate ocean zones to tropical ones, yet rarely seen by humans, the oarfish family contains three species in two genus, genera. One of these, the giant oarfish (''Regalecus glesne''), is the longest bony fish alive, growing up to about in length. The common name ''oarfish'' is thought to allude either to their highly compressed and elongated bodies, or to the now discredited belief that the fish "row" themselves through the water with their pelvic fins. The family name Regalecidae is derived from the Latin ''regalis'', meaning "royal". Although the larger species are considered game fish and are fished commercially on a small scale, oarfish are rarely caught alive; their flesh is not well regarded for eating due to its gelatinous consistency. Their rarity and large size, and their habit of lingering at the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Regalecus Russelii
''Regalecus russelii'', or Russell's oarfish, is a species of oarfish in the family Regalecidae. It is a broadly-distributed marine fish, found in waters in the bathypelagic zone. ''R. russelii'' is a scaleless, elongate and ribbonlike fish, growing up to 8 meters in length. Taxonomy ''Regalecus russelii'' is a member of the fish genus Regalecus and oarfish family Regalecidae. The genus currently includes only one other species of oarfish, ''Regalecus glesne''. ''R. russelii'' is part of the order Lampriformes, which represents tube-eyes and ribbonfishes, and is part of the larger class of ray-finned fishes called Actinopterygii. Anatomy and morphology ''Regalecus russelii'' can grow up to 8 meters in length, and it has two dorsal fin crests that can reach 1 meter high. The species can be distinguished by its red dorsal fin crests, light brown head, and scaleless, silver body. The body is covered by dermal tubercles, which are concentrated along the ventral and lower side re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Giant Oarfish
The giant oarfish (''Regalecus glesne'') is a species of oarfish of the Family (biology), family Regalecidae. It is an oceanodromous species with a worldwide distribution, excluding polar regions. Other common names include Pacific oarfish, king of herrings, ribbonfish, and streamer fish. ''R. glesne'' is the world's longest ray-finned fish. Its shape is ribbon-like, narrow laterally, with a dorsal fin along its entire length, stubby pectoral fins, and long, oar-shaped pelvic fins, from which its common name is derived. Its coloration is silver and blue with spots of dark pigmentation, and its fins are crimson. Its physical characteristics and undulating mode of swimming have led to speculation that it might be the source of many "sea serpent" sightings. Taxonomy ''R. glesne'' was first described by Peter Ascanius in 1772. The genus name, ''Regalecus'' (from Latin ‘regalis’ meaning royal), signifies "belonging to a king"; the specific epithet ''glesne'' is from "Glesnaes", th ...

Lampriform
Lampriformes is an order of ray-finned fish. Members are collectively called lamprids (which is more properly used for the Lampridae) or lampriforms, and unite such open-ocean and partially deep-sea Teleostei as the crestfishes, oarfish, opahs, and ribbonfishes. A synonym for this order is Allotriognathi, while an often-seen, but apparently incorrect, spelling variant is Lampridiformes. They contain seven extant families which are generally small but highly distinct, and a mere 12 lampriform genera with some 20 species altogether are recognized. They are the only extant members of the superorder Lamprimorpha, which was formerly diverse throughout much of the Late Cretaceous. The scientific name literally means "shaped (like the) bright (one)", as "lampr-", meaning bright, comes from ''lampris'', the generic name for the opah. In contrast, most other living lampriforms are actually ribbon-like and not very similar to the disc-shaped opahs in habitus. They are, however, quite ...

Sea Serpent
A sea serpent is a type of sea monster described in various mythologies, most notably in Mesopotamian cosmology (Tiamat), Ugaritic cosmology ( Yam, Tannin), biblical cosmology (Leviathan, Rahab), Greek cosmology (Cetus, Echidna, Hydra, Scylla), and Norse cosmology (Jörmungandr). Mythology Mediterranean and Western Asia The mytheme, the chief god in the role of the hero slaying a sea serpent, is widespread both in the ancient Near East and in Indo-European mythology, e.g. Lotan and Hadad, Leviathan and Yahweh, Tiamat and Marduk (see also Labbu, Bašmu, Mušḫuššu), Illuyanka and Tarhunt, Yammu and Baal in the Baal Cycle etc. The Hebrew Bible also has mythological descriptions of large sea creatures as part of creation under Yahweh's command, such as the Tanninim mentioned in Book of Genesis 1:21 and the "great serpent" of Amos 9:3. In the Aeneid, a pair of sea serpents killed Laocoön and his sons when Laocoön argued against bringing the Trojan Horse into Tr ...

Agrostichthys
''Agrostichthys parkeri'', also called the streamer fish, is a species of oarfish. Only seven identified specimens have been examined, with few found fully intact, and have mainly been found in the Southern Ocean. ''Agrostichthys parkeri'' belongs to the Regalecidae (oarfish) family in the Lampriformes order and is the only known member of its genus. This species has been known to grow up to long and has a ribbon-like body, two large eyes, a protruding mouth and long filamentous rays originating at the head. Due to only seven specimens being found, only the distribution and anatomy of ''Agrostichthys parkeri'' can be documented. Etymology The fish is named in memory of Benham’s predecessor, zoologist Thomas Jeffery Parker (1850-1897), of the University of Otago in New Zealand, who made a “careful study” of the anatomy of ''Regalecus glesne'' in the year 1886. Anatomy and morphology ''Agrostichthys parkeri'' has an elongated, vertically compressed body which slims down ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bony Fish
Osteichthyes ( ; ), also known as osteichthyans or commonly referred to as the bony fish, is a Biodiversity, diverse clade of vertebrate animals that have endoskeletons primarily composed of bone tissue. They can be contrasted with the Chondrichthyes (cartilaginous fish) and the extinct placoderms and acanthodians, which have endoskeletons primarily composed of cartilage. The vast majority of extant taxon, extant fish are members of Osteichthyes, being an extremely diverse and abundant group consisting of 45 order (biology), orders, over 435 family (biology), families and 28,000 species. The group is divided into two main clades, the ray-finned fish (Actinopterygii, which makes up the vast majority of extant fish) and the lobe-finned fish (Sarcopterygii, which gave rise to all land vertebrates, i.e. tetrapods). The oldest known fossils of bony fish are about 425 million years old from the late Silurian, which are also transitional fossils showing a dentition, tooth pattern th ...

Fish Fin
Fins are moving appendages protruding from the body of fish that interact with water to generate thrust and help the fish swim. Apart from the tail or caudal fin, fish fins have no direct connection with the back bone and are supported only by muscles. Fish fins are distinctive anatomical features with varying structures among different clades: in ray-finned fish (Actinopterygii), fins are mainly composed of bony spines or rays covered by a thin stretch of scaleless skin; in lobe-finned fish ( Sarcopterygii) such as coelacanths and lungfish, fins are short rays based around a muscular central bud supported by jointed bones; in cartilaginous fish ( Chondrichthyes) and jawless fish ( Agnatha), fins are fleshy " flippers" supported by a cartilaginous skeleton. Fins at different locations of the fish body serve different purposes, and are divided into two groups: the midsagittal ''unpaired fins'' and the more laterally located ''paired fins''. Unpaired fins are p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pectoral Fin
Fins are moving appendages protruding from the body of fish that interact with water to generate thrust and help the fish aquatic locomotion, swim. Apart from the tail or caudal fin, fish fins have no direct connection with the vertebral column, back bone and are supported only by muscles. Fish fins are distinctive anatomical features with varying structures among different clades: in ray-finned fish (Actinopterygii), fins are mainly composed of bone, bony spine (zoology), spines or ray (fish fin anatomy), rays covered by a thin stretch of fish scale, scaleless skin; in lobe-finned fish (Sarcopterygii) such as coelacanths and lungfish, fins are short rays based around a muscular central limb bud, bud supported by appendicular skeleton, jointed bones; in cartilaginous fish (Chondrichthyes) and jawless fish (Agnatha), fins are fleshy "flipper (anatomy), flippers" supported by a cartilaginous skeleton.
