Are Flatfishes (Pleuronectiformes) Monophyletic? [PDF]

open access: yesMolecular Phylogenetics and Evolution, 2013
All extant species of flatfish (order Pleuronectiformes) are thought to descend from a common ancestor, and therefore to represent a monophyletic group. This hypothesis is based largely on the dramatic bilateral asymmetry and associated ocular migration characteristics of all flatfish. Yet, molecular-based phylogenetic studies have been inconclusive on

Phylogeny of Flatfishes (Pleuronectiformes): Comparisons and Contradictions of Molecular and Morpho-Anatomical Data

open access: yesJournal of Fish Biology, 1994
International audienceSeveral species of flatfishes (Pleuronectiformes) have been studied by isoenzyme electrophoresis and DNA/DNA hybridization to establish the evolutionary relationships of this group of fishes.

Analysis of the morphogenesis and cell proliferation in the retina of a pleuronectiform fish, the turbot psetta maxima (Pleuronectiformes: Teleostei)

Microscopy Research and Technique, 2013
ABSTRACTThe morphogenesis and cell proliferation in the retina of turbot (Psetta maxima, Pleuronectiformes: Teleostei) from embryo through metamorphosis have been examined by using proliferating cell nuclear antigen (PCNA)‐immunohistochemistry and general histological procedures.

Flatfish (Pleuronectiformes) chromatic biology

Reviews in Fish Biology and Fisheries, 2009
The following aspects of flatfish skin coloration are reviewed. (1) The variety of chromatophores which contribute to the complex integumentary patterns; their relative sizes and numerical distribution. (2) Interspecific variations and intraspecific changes in skin patterns.

On the morphology of the alimentary tract of flatfishes (Pleuronectiformes)

Journal of Fish Biology, 1973
The changes during the life cycle in the relative length of certain parts of the alimentary tract, buccal‐pharyngeal cavity, oesophagus‐stomach, intestine, rectum—are investigated in the five North Sea flatfish species, viz. turbot, brill, plaice, dab, sole.

Adaptation in the jaws of flatfish (Pleuronectiformes)

Journal of Zoology, 1969
The structure and mechanisms of the jaws of 18 species of flatfish have been investigated. Clear adaptations to different modes of feeding were found. The mechanisms of the jaws of Soleidae, Cynoglossidae, and Rhombosoleinae are highly specialized and the representatives of the two latter groups have some interesting jaw muscles of doubtful homology.

Phylogenetic Status of Paralichthodes algoensis (Pleuronectiformes: Paralichthodidae)

Copeia, 1998
The phylogenetic position and classification of the flatfish, Paralichthodes algoensis, have been subject to several changes since its description by Gilchrist (1902). Regan (1910) classified this South African species within the Samarinae, along with Brachypleura and Samaris, based on the absence of a distinct caudal peduncle, the forward extension of

Revision of the Genus Asterorhombus (Pleuronectiformes: Bothidae)

Copeia, 2005
Abstract A recent definition of Asterorhombus is composed of only two characters: lack of sexual dimorphism; deep clefts in caudal bones (parhypural, hypurals, epurals). The genus currently contains seven nominal species: A. annulatus, A. bleekeri, A. osculus, A. cocosensis, A. fijiensis, A. intermedius, and A. filifer.
