Retracted: Evolution and development of the homocercal caudal fin in teleosts

  title={Retracted: Evolution and development of the homocercal caudal fin in teleosts},
  author={Yuuta Moriyama and Hiroyuki Takeda},
The vertebrate caudal skeleton is one of the most innovative structures in vertebrate evolution and has been regarded as an excellent model for functional morphology, a discipline that relates a structure to its function. Teleosts have an internally‐asymmetrical caudal fin, called the homocercal caudal fin, formed by the upward bending of the caudal‐most portion of the body axis, the ural region. This homocercal type of the caudal fin ensures powerful and complex locomotion and is thought to be… Expand
Skeletal development in the heterocercal caudal fin of spotted gar (lepisosteus oculatus) and other lepisosteiformes
The development of the caudal fin of spotted gar Lepisosteus oculatus is examined, one of only eight living species of Holostei, the sister group to the teleosts, and provides bases for future evolutionary and morphological investigations on actinopterygians fins. Expand
Early Development of the Caudal Fin Skeleton of Capelin, Mallotus villosus (Osmeridae)
Development of the caudal fin skeleton of capelin, Mallotus villosus, is described based on observations of cleared-and-stained specimens from a wild caught growth series and a ventral-to-dorsal developmental gradient in the caUDal fin elements and anterior-posterior gradient in development of vertebral centra are discussed.

Epural bones in teleost fishes: a problem of phylogenetic homology
It is demonstrated that “higher” teleost fishes show a variety of patterns of epural formation and development and that some of these may be phylogenetically informative characters. Expand
Tetrapod axial evolution and developmental constraints; Empirical underpinning by a mouse model
It is concluded that the ancestral, pre-tetrapodial Hox code already possessed the capacity to induce vertebrae with sacral characteristics, and alterations in the interpretation of the H Cox code may have participated to the evolution of this region in tetrapods. Expand
Comparative anatomy of the caudal skeleton of lantern fishes of the genus Triphoturus Fraser-Brunner, 1949 (Teleostei: Myctophidae)
This osteological description of the caudal region allowed updates to the nomenclature of bony and cartilaginous elements in myctophids and allows for the recognition of structural differences between T. mexicanus and T. oculeum, as well as the major morphological distinction betweenT. Expand
The making of an octopus arm
By understanding the general dynamics of octopus arm formation, this work established a basis for further studies on appendage patterning, growth, and differentiation in a representative of the lophotrochozoan super phylum. Expand
a r t i c l e i n f o The tetrapod vertebral column has become increasingly complex during evolution as an adaptation to a terrestrial life. At the same time, the evolution of the vertebral formulaExpand
Selenomethionine exposure affects chondrogenic differentiation and bone formation in Japanese medaka (Oryzias latipes).
It is demonstrated that Se-Met modulates expression of key genes involved in chondrogenic differentiation and bone formation during development, supporting involvement of Mtr. Expand
Exposure to a PBDE/OH-BDE mixture alters juvenile zebrafish (Danio rerio) development.
Exposure to PBDE/OH-BDE mixtures adversely impact zebrafish maturation during metamorphosis, and assessment of thyroid and osteochondral gene regulatory networks demonstrated significantly increased expression of genes that regulate skeletal development and thyroid hormones. Expand


Caudal fin locomotion in ray-finned fishes: historical and functional analyses
Historical, phylogenetic patterns in the axial musculoskeletal system need to be integrated with experimental and functional data in order to understand the design of the locomotor apparatus in vertebrates, and functional symmetry in the tail of ray-finned fishes is suggested to be not predictable from skeletal morphology alone. Expand
Functional morphology of the caudal skeleton in teleostean fishes
This basic caudal skeleton in teleostean fishes varies with the position of the fish in the sequence of teleosten evolution, the way in which the fish uses its caUDal fin, and to some extent with the shape of the fin. Expand
Function of the Caudal Fin During Locomotion in Fishes: Kinematics, Flow Visualization, and Evolutionary Patterns1
Two experimental approaches are reviewed which promise to provide new insights into the function and evolution of the caudal fin: three-dimensional kinematic analysis, and quantitative flow measurements in the wake of freely-swimming fishes using digital particle image velocimetry (DPIV). Expand
The Structure and Development of the Caudal Skeleton of the Teleostean Fish, Pleuragramma antarcticum.
The hypural bones of the adult are formed by a fusion of haemal arches and radials, and this compound nature of the hypurals may be seen anteriorly in adult Selachians and in the Sturgeon, but it has not been shown before, as far as I am aware, in Teleosts. Expand
The Medaka zic1/zic4 Mutant Provides Molecular Insights into Teleost Caudal Fin Evolution
A detailed analysis of the spontaneous medaka (teleost fish) mutant, Double anal fin, shows that zic1/zic4 are strongly expressed in the dorsal part of the ural mesenchyme and thereby induce asymmetric caudal fin development in wild-type embryos, whereas their expression is lost in Da. Expand

The developmental morphology of the axial skeleton of zebrafish is described and reviewed in relation to the morphology of related species and the relative sequence of ossification in the skeleton is described. Expand
Trunk exoskeleton in teleosts is mesodermal in origin
The embryonic origin of scales and fin rays of medaka (teleost trunk exoskeletons) is determined by applying long-term cell labelling methods, and it is demonstrated that both tissues are mesodermal in origin. Expand
Leis' conundrum: Homology of the clavus of the ocean sunfishes. 1. Ontogeny of the median fins and axial skeleton of Monotrete leiurus (Teleostei, Tetraodontiformes, Tetraodontidae)
The ontogeny of the axial skeleton and median fins of the Southeast Asian freshwater puffer Monotrete leiurus is described, based on a reared developmental series, and the proximal‐middle radials of the dorsal and anal fins are upright and symmetrical and their distal tips coalesce during development to form a deep band of cartilage, from which the spherical distal radials are spatially separated.

Ontogeny, variation, and homology in Salvelinus alpinus caudal skeleton (Teleostei: Salmonidae)
Evidence is provided that a seventh hypural and a fourth uroneural are taxic atavism in salmonids, and the development of the salmonid homocercal fin is discussed in the light of a polyural scheme based on evidences of a one‐to‐one relationship among ural centra and their associated elements.

Some points in the function, development and evolution of the tail in fishes*
Models show that in fishes the effective action of a tail in a vertical direction depend on the relative size of the epichordal and hypochordal lobes; the flexibility of the fins; and the direction of the terminal part of the axis, which indicates that the tail is isobatic throughout development.
