Cruciglanis
''Cruciglanis'' is a genus of catfish ( order Siluriformes) of the family Pseudopimelodidae. It contains a single recognized species, ''Cruciglanis pacifici''.

Pseudopimelodidae
The Pseudopimelodidae are a small family (about 40 species) of catfishes known as the bumblebee catfishes or dwarf marbled catfishes. Some of these fish are popular aquarium fish. Taxonomy This family was formerly a subfamily of Pimelodidae. Pseudopimelodidae is a monophyletic group. Previously, the superfamily Pseudopimelodoidea was sister to superfamilies Sisoroidea + Loricarioidea. However, some evidence has shown this family, along with Pimelodidae, Heptapteridae, and ''Conorhynchos'', may form a monophyletic assemblage, which contradicts the hypothesis that the former family Pimelodidae that included these families is a polyphyletic group. Distribution The Pseudopimelodidae are restricted to fresh water in South America, from the Atrato River in Colombia to Argentina in the Río de la Plata The Río de la Plata (, "river of silver"), also called the River Plate or La Plata River in English, is the estuary formed by the confluence of the Uruguay River and the Paran ...

Fish Measurement
Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries biology. Overall length * Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. Simply put, this measurement excludes the length of the caudal (tail) fin. * Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini ( hagfish), Petromyzontiformes ( lampreys), and (usually) Elasmobranchii (shark Sharks are a group of elasmobranch fish chara ...

Diptera
Flies are insects of the order Diptera, the name being derived from the Greek δι- ''di-'' "two", and πτερόν ''pteron'' "wing". Insects of this order use only a single pair of wings to fly, the hindwings having evolved into advanced mechanosensory organs known as halteres, which act as high-speed sensors of rotational movement and allow dipterans to perform advanced aerobatics. Diptera is a large order containing an estimated 1,000,000 species including horse-flies, crane flies, hoverflies and others, although only about 125,000 species have been described. Flies have a mobile head, with a pair of large compound eyes, and mouthparts designed for piercing and sucking (mosquitoes, black flies and robber flies), or for lapping and sucking in the other groups. Their wing arrangement gives them great maneuverability in flight, and claws and pads on their feet enable them to cling to smooth surfaces. Flies undergo complete metamorphosis; the eggs are often laid on the l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trichoptera
The caddisflies, or order Trichoptera, are a group of insects with aquatic larvae and terrestrial adults. There are approximately 14,500 described species, most of which can be divided into the suborders Integripalpia and Annulipalpia on the basis of the adult mouthparts. Integripalpian larvae construct a portable casing to protect themselves as they move around looking for food, while Annulipalpian larvae make themselves a fixed retreat in which they remain, waiting for food to come to them. The affinities of the small third suborder Spicipalpia are unclear, and molecular analysis suggests it may not be monophyletic. Also called sedge-flies or rail-flies, the adults are small moth-like insects with two pairs of hairy membranous wings. They are closely related to the Lepidoptera (moths and butterflies) which have scales on their wings; the two orders together form the superorder Amphiesmenoptera. The aquatic larvae are found in a wide variety of habitats such as streams, riv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insect
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trichomycterus Taenia
''Trichomycterus'' is a genus of fish in the family Trichomycteridae, the largest genus of its family with over 170 species currently described. This genus is native to freshwater habitats in Central and South America. These fish are generally small, usually about in standard length, although the largest, '' T. rivulatus'', can reach more than twice this size. Species differ from one another primarily in body proportions, fin ray counts and colouration.Fernández, L. & Osinaga, K. (2006)A New ''Trichomycterus'' (Siluriformes: Trichomycteridae) from Aguarague National Park of the Bolivian Preandean Region, with Comments on Relationships within of the Genus.''Environmental Biology of Fishes, 75 (4): 385–393.'' Despite their relatively small size, some, such as '' T. punctulatus'', support fisheries and are important in the local cuisine. Taxonomy This genus is defined by the lack of specializations found in other trichomycterids and is certainly polyphyletic.Alencar, A.R. & Costa ...

Gobiesox
''Gobiesox'' is a genus of clingfishes found in the Americas, including offshore islands. Most species inhabit coastal marine and brackish waters, but ''G. lanceolatus'' is a deep-water species found at a depth of around , and seven species (''G. cephalus'', ''G. fluviatilis'', ''G. fulvus'', ''G. juniperoserrai'', ''G. juradoensis'', ''G. mexicanus'' and ''G. potamius'') are from fast-flowing rivers and streams. These seven are the only known freshwater clingfish. The genus includes both widespread and common species, and more restricted species that are virtually unknown. Three freshwater species that are endemic to Mexico (''G. fluviatilis'', ''G. juniperoserrai'' and ''G. mexicanus'') are considered threatened by Mexican authorities, and three species that are endemic to small offshore islands (''G aethus'' and ''G. canidens'' of the Revillagigedo Islands, and ''G. woodsi'' of Cocos Island) are considered vulnerable by the IUCN.
