Bathysauridae
The Bathysauridae are a small family of deepwater aulopiform fish, related to the telescopefishes. The two species in the family both belong to the genus ''Bathysaurus''. Commonly called deepwater lizardfishes or deepsea lizardfishes, the latter name usually refers to the species ''B. ferox'' specifically. Physically, the bathysaurids resemble the lizardfishes, as reflected in their common names. They can be distinguished from the lizardfishes by their flatter heads and curved and barbed teeth. They are moderately sized fish, up to in length. Bathysaurids inhabit the deep oceans, below depth. They are one of the world's deepest living apex predators, and will not hesitate to eat anything they meet, including their own kind. Their larvae were originally believed to represent a distinct genus (''Macristium'') and even family. The two Bathysaurid species, ''Bathysaurus mollis'' and ''Bathysaurus ferox'' are hermaphrodite In reproductive biology, a hermaphrodite () is an o ...

Aulopiformes
Aulopiformes is a diverse order of marine ray-finned fish consisting of some 15 extant and several prehistoric families with about 45 genera and over 230 species. The common names grinners, lizardfishes and allies, or aulopiforms are sometimes used for this group. The scientific name means "''Aulopus''-shaped", from ''Aulopus'' (the type genus) + the standard fish order suffix "-formes". It ultimately derives from Ancient Greek ''aulós'' (αὐλός, "flute" or "pipe") + Latin ''forma'' ("external form"), the former in reference to the elongated shape of many aulopiforms.FishBase (2000) They are grouped together because of common features in the structure of their gill arches. Indeed, many authors have considered them so distinct as to warrant separation in a monotypic superorder of the Teleostei, under the name Cyclosquamata. However, monotypic taxa are generally avoided by modern taxonomists if not necessary, and in this case a distinct superorder seems indeed unwarra ...

Bathysaurus Ferox
The deepsea lizardfish, ''Bathysaurus ferox'', is an aulopiform of the family Bathysauridae, found in tropical and subtropical seas across the world. The deepsea lizardfish should not be confused with the true or "typical" lizardfishes of the related family Synodontidae. Taxonomy Deepsea lizardfishes were first described in 1878 by British zoologist Albert Günther, who created the generic name from ancient Greek word elements “''báthos''” and “''saûros''” meaning “lizard of the depths”. Previously recognized in the synodontidae, in 1996, Robert Karl Johnson et al. showed its relationships outside synodontidae, in its own family in the suborder Giganturoidei. At the beginning of the century, ''Bathysaurus ferox'' larvae were thought to be a distinct species called ''Macristium chavesi''. Johnson gave evidence of the synonymy of the two species. Appearance Deep-sea lizardfish resemble shallow-water lizardfishes, as reflected in their common names. Adults reach ove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lizardfish
The Synodontidae or lizardfishes(or typical lizardfish to distinguish them from the Bathysauridae and Pseudotrichonotidae) are benthic (bottom-dwelling) marine and estuarine bony fishes that belong to the aulopiform fish order, a diverse group of marine ray-finned fish consisting of some 15 extant and several prehistoric families. They are found in tropical and subtropical marine waters throughout the world. Lizardfishes are generally small, although the largest species measures about in length. They have slender, somewhat cylindrical bodies, and heads that superficially resemble those of lizards. The dorsal fin is located in the middle of the back, and accompanied by a small adipose fin placed closer to the tail. They have mouths full of sharp teeth, even on the tongue. Lizardfishes are benthic animals that live in shallow coastal waters; even the deepest-dwelling species of lizardfish live in waters no more than deep. Some species in the subfamily Harpadontinae live in bra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bathysaurus Mollis
''Bathysaurus mollis'' is a species of fish in the family Bathysauridae The Bathysauridae are a small family of deepwater aulopiform fish, related to the telescopefishes.

Albert Günther
Albert Karl Ludwig Gotthilf Günther FRS, also Albert Charles Lewis Gotthilf Günther (3 October 1830 – 1 February 1914), was a German-born British zoologist, ichthyologist, and herpetologist. Günther is ranked the second-most productive reptile taxonomist (after George Albert Boulenger) with more than 340 reptile species described. Early life and career Günther was born in Esslingen in Swabia (Württemberg). His father was a ''Stiftungs-Commissar'' in Esslingen and his mother was Eleonora Nagel. He initially schooled at the Stuttgart Gymnasium. His family wished him to train for the ministry of the Lutheran Church for which he moved to the University of Tübingen. A brother shifted from theology to medicine, and he, too, turned to science and medicine at Tübingen in 1852. His first work was "''Ueber den Puppenzustand eines Distoma''". He graduated in medicine with an M.D. from Tübingen in 1858, the same year in which he published a handbook of zoology for students of ...

Telescopefish
Telescopefish are small, deep-sea aulopiform fish comprising the small family Giganturidae. The two known species are within the genus ''Gigantura''. Though rarely captured, they are found in cold, deep tropical to subtropical waters worldwide. The common name of these fish is related to their bizarre, tubular eyes. The genus name ''Gigantura'' refers to the Gigantes, a race of giants in Greek mythology—coupled with the suffix ''oura'', meaning 'tail', thus ''Gigantura'' refers to the greatly elongated, ribbon-like lower half of the tailfin that may comprise over half of the total body length. Species The currently recognized species in this genus are: * ''Gigantura chuni'' A. B. Brauer, 1901 (gigantura) * ''Gigantura indica'' A. B. Brauer, 1901 (telescopefish) Description The Giganturidae are slender, slightly tapered fish with large heads dominated by large, forward-pointing, telescoping eyes with large lenses. Their heads end in short, pointed snouts. The highly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cannibalism
Cannibalism is the act of consuming another individual of the same species as food. Cannibalism is a common ecological interaction in the animal kingdom and has been recorded in more than 1,500 species. Human cannibalism is well documented, both in ancient and in recent times. The rate of cannibalism increases in nutritionally poor environments as individuals turn to members of their own species as an additional food source.Elgar, M.A. & Crespi, B.J. (1992) ''Cannibalism: ecology and evolution among diverse taxa'', Oxford University Press, Oxford ngland New York. Cannibalism regulates population numbers, whereby resources such as food, shelter and territory become more readily available with the decrease of potential competition. Although it may benefit the individual, it has been shown that the presence of cannibalism decreases the expected survival rate of the whole population and increases the risk of consuming a relative. Other negative effects may include the increased r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Larva
A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle. The larva's appearance is generally very different from the adult form (''e.g.'' caterpillars and butterflies) including different unique structures and organs that do not occur in the adult form. Their diet may also be considerably different. Larvae are frequently adapted to different environments than adults. For example, some larvae such as tadpoles live almost exclusively in aquatic environments, but can live outside water as adult frogs. By living in a distinct environment, larvae may be given shelter from predators and reduce competition for resources with the adult population. Animals in the larval stage will consume food to fuel their transition into the adult form. In some organisms like polychaetes and barnacles, adults are immobil ...

Hermaphrodite
In reproductive biology, a hermaphrodite () is an organism that has both kinds of reproductive organs and can produce both gametes associated with male and female sexes. Many Taxonomy (biology), taxonomic groups of animals (mostly invertebrates) do not have separate sexes. In these groups, hermaphroditism is a normal condition, enabling a form of sexual reproduction in which either partner can act as the female or male. For example, the great majority of tunicata, tunicates, pulmonate molluscs, opisthobranch, earthworms, and slugs are hermaphrodites. Hermaphroditism is also found in some fish species and to a lesser degree in other vertebrates. Most plants are also hermaphrodites. Animal species having different sexes, male and female, are called Gonochorism, gonochoric, which is the opposite of hermaphrodite. There are also species where hermaphrodites exist alongside males (called androdioecy) or alongside females (called gynodioecy), or all three exist in the same species ( ...
