Apogonoidei
The Apogonoidei is a suborder of gobiiform fish consisting of two families: the Indo-Pacific Kurtidae (consisting solely of two species in the genus ''Kurtus'') and the much more diverse and widespread Apogonidae (the cardinalfishes). The order is part of the Percomorpha clade and, based on phylogenetic evidence, is considered a sister taxon to the gobies and sand divers. In some older treatments, it is instead treated as its own order, Kurtiformes (). Relationships and defining characteristics A close relationship between the Kurtidae and Apogonidae was postulated based on the similarity of constituent parts of their dorsal gill arches and that in both groups the eggs have filaments on the micropyle, which enable the eggs to form a mass. This mass is brooded in the mouth in the Apogonidae and borne on the supraoccipital hook of at least one of the two nursery fishes in the Kurtidae. They also have horizontal and vertical rows of sensory papillae on their heads and bodies, whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gobiiformes
Gobiiformes (meaning "goby-like") is an order of percomorph fish containing three suborders: Apogonoidei, Trichonotoidei, and Gobioidei. The order was formerly defined as containing only the gobies (now placed within the Gobioidei). However, more recent taxonomic treatments also place their close relatives (the cardinalfishes, nurseryfishes, and sand-divers) with them, based on phylogenetic studies that unexpectedly found a close relationship between these groups. The Gobioidei are the most speciose clade of the family. Despite the differing appearances of members of this group, all share the trait of adhesive eggs with elaborate structures. Many species within this group also display elaborate forms of parental care by the male. Gobiiforms are a relatively basal clade of the percomorphs, with only the ophidiiforms and batrachoidiforms being more basal. They are estimated to have diverged from the rest of the group during the early-to-mid Cretaceous (about 120 million ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gobioidei
The Gobioidei are a suborder of percomorph fish. Many of these fishes are called gobies. It is by far the largest and most diverse order within the order Gobiiformes, and one of the most diverse groups of ray-finned fish in general. The suborder, which was previously considered a suborder of Perciformes, is made up of about 2,211 species that are divided between seven families. Phylogenetic relationships of the Gobioidei have been elucidated using molecular data. Gobies are primarily small species, often with large heads and tapered bodies, that live in marine water, but roughly 10% of these species inhabit fresh water. This order is composed chiefly of benthic or burrowing species; like many other benthic fishes, most gobioids do not have a gas bladder or any other means of controlling their buoyancy in water, so they must spend most of their time on or near the bottom. Traditionally most of the species called gobies have been classified in the order Perciformes as the suborder ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Percomorpha
Percomorpha () is an extremely large and diverse clade of ray-finned fish. With more than 17,000 known species (including Scombroidei, tuna, Syngnathiformes, seahorses, gobies, Cichlidae, cichlids, flatfish, Labridae, wrasse, Perciformes, perches, Lophiiformes, anglerfish, and Tetraodontiformes, pufferfish) known from both marine and freshwater ecosystems, it is the most speciose clade of extant Vertebrate, vertebrates. Evolution Percomorpha are the most biodiversity, diverse group of teleost fish today. Teleosts, and percomorphs in particular, thrived during the Cenozoic Era (geology), era. Fossil evidence shows that there was a major increase in size and abundance of teleosts immediately after the mass extinction event at the Cretaceous–Paleogene extinction event, Cretaceous-Paleogene boundary ago. The oldest known percomorph fossils are of the early Tetraodontiformes, tetraodontiforms ''Protriacanthus'' and Cretatriacanthidae from the Santonian to Campanian of Italy and Slov ...

Fish Anatomy
Fish anatomy is the study of the form or Morphology (biology), morphology of fish. It can be contrasted with fish physiology, which is the study of how the component parts of fish function together in the living fish. In practice, fish anatomy and fish physiology complement each other, the former dealing with the structure of a fish, its organs or component parts and how they are put together, such as might be observed on the dissecting table or under the microscope, and the latter dealing with how those components function together in living fish. The anatomy of fish is often shaped by the physical characteristics of water, the medium in which fish live. Water is much density, denser than air, holds a relatively small amount of dissolved oxygen, and absorbs more light than air does. The body of a fish is divided into a head, trunk and tail, although the divisions between the three are not always externally visible. The skeleton, which forms the support structure inside the fish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Otolith
An otolith (, ' ear + , ', a stone), also called otoconium, statolith, or statoconium, is a calcium carbonate structure in the saccule or utricle (ear), utricle of the inner ear, specifically in the vestibular system of vertebrates. The saccule and utricle, in turn, together make the ''otolith organs''. These organs are what allows an organism, including humans, to perceive linear acceleration, both horizontally and vertically (gravity). They have been identified in both extinct and extant vertebrates. Counting the annual growth rings on the otoliths is a common technique in estimating the age of fish. Description Endolymphatic infillings such as otoliths are structures in the saccule and Utricle (ear), utricle of the inner ear, specifically in the Labyrinth (inner ear), vestibular labyrinth of all vertebrates (fish, amphibians, reptiles, mammals and birds). In vertebrates, the saccule and utricle together make the ''otolith organs''. Both statoconia and otoliths are used as gra ...

Acropomatiformes
The Acropomatiformes or Pempheriformes are an order of fish from the group of perch relatives Percomorpha. The relationship of the families assigned to the Acropomatiformes is based on molecular biological studies and is not yet supported by morphological characteristics. The giant sea bass (''Stereolepis gigas'') of the Eastern Pacific Ocean, with a maximum length of and weight of , is the largest species of the Pempheriformes. As early as 2007, Smith and Craig established a relationship between the wreckfish Polyprionidae, the longfin pike Dinolestes lewini, the armored heads Pentacerotidae and the lanternbellies Acropomatidae. In February 2009, Blaise Li and colleagues described a monophyletic clade composed of the Howellidae, the Lateolabracidae and the deep-sea cardinalfishes Epigonidae in their analysis of the relationships between the various groups of the Acanthomorpha. In a revision of the bony fish systematics published in early 2013 by Ricardo Betancur-R. and c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albert Günther
Albert Karl Ludwig Gotthilf Günther , also Albert Charles Lewis Gotthilf Günther (3October 18301February 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''" (On the pupal state of ''Distoma''). He graduated in medicine with an M.D. from Tübingen in 1858, the same year in which he published a handbook ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pieter Bleeker
Pieter Bleeker (10 July 1819 – 24 January 1878) was a Dutch medical doctor, Ichthyology, ichthyologist, and Herpetology, herpetologist. He was famous for the ''Atlas Ichthyologique des Indes Orientales Néêrlandaises'', his monumental work on the fishes of East Asia published between 1862 and 1877. Life and work Bleeker was born on 10 July 1819 in Zaandam. He was employed as a medical officer in the Royal Netherlands East Indies Army from 1842 to 1860, (in French). stationed in the Dutch East Indies (now Indonesia). During that time, he did most of his ichthyology work, besides his duties in the army. He acquired many of his specimens from local fishermen, but he also built up an extended network of contacts who would send him specimens from various government outposts throughout the islands. During his time in Indonesia, he collected well over 12,000 specimens, many of which currently reside at the Naturalis Biodiversity Center in Leiden. Bleeker corresponded with Auguste Dum� ...

Phylogeny
A phylogenetic tree or phylogeny is a graphical representation which shows the evolutionary history between a set of species or Taxon, taxa during a specific time.Felsenstein J. (2004). ''Inferring Phylogenies'' Sinauer Associates: Sunderland, MA. In other words, it is a branching diagram or a tree (graph theory), tree showing the evolutionary relationships among various biological species or other entities based upon similarities and differences in their physical or genetic characteristics. In evolutionary biology, all life on Earth is theoretically part of a single phylogenetic tree, indicating common ancestry. Phylogenetics is the study of phylogenetic trees. The main challenge is to find a phylogenetic tree representing optimal evolutionary ancestry between a set of species or taxa. computational phylogenetics, Computational phylogenetics (also phylogeny inference) focuses on the algorithms involved in finding optimal phylogenetic tree in the phylogenetic landscape.
