To investigate the relationships among the three main groups of extant neopterygian fishes--Amiidae, Lepisosteidae, and Teleostei--we sequenced fragments of three mitochondrial genes from 12 different actinopterygian fishes and translated the nucleotide sequences into amino acid sequences. When all three regions are considered together, Amiidae clusters with Lepisosteidae in the most parsimonio...

A set of cytological studies performed in the utricle and saccule of Astronotus ocellatus (Teleostei, Percomorphi, Cichlidae) identified two basic types of hair cells and others with some intermediate characteristics. This paper reports on applying the same techniques to the saccule of Carassius auratus (Teleostei, Otophysi, Cyprinidae) and demonstrates similar types of hair cells to those foun...

The infraclass Teleostei is a highly diversified group of bony fishes that encompasses 96% of all species of living fishes and almost half of extant vertebrates. Evolution of various morphological complexes in teleosts, particularly those involving soft anatomy, remains poorly understood. Notable among these problematic complexes is the adductor mandibulae, the muscle that provides the primary ...

Rhinobatos percellens is one of three species of Rhinobatidae found on Brazilian shores and is one of the most abundant species on the shallow continental shelf of Paraná and Santa Catarina States. Specimens caught by artisanal fishery between July/2001 and March/2003 by fishing communities located on the frontier between two southern Brazilian States (Paraná and Santa Catarina) had their stoma...

the present study reports range extansion of moenkhausia oligolepis to the pindaré river drainage, of the mearim river basin, and itapecuru river basin, maranhão state, northeastern brazil. this species was previously known only from venezuela, guianas, and the amazon river basins. in addition, we present some meristic and morphometric data of the specimens herein examined and discuss on its di...

Gyrodactylus latus Bychowsky, 1933 (Monogenea, Gyrodactylidae) was found on fins of Cobitis elongatoides Bacescu et Maier, 1969 (Teleostei, Cobitidae) from tributaries of the Stobrawa River (Odra Basin, Silesia, Poland). It is new to the Polish parasite fauna; its description, measurements, and figures are presented.

We show that RNF213 is a nuclear gene suitable for investigating large scale acanthomorph teleosteans interrelationships. The gene recovers many clades already found by several independent studies of acanthomorph molecular phylogenetics and considered as reliable. Moreover, we performed phylogenetic analyses of three other independent nuclear markers, first separately and then of all possible c...

the toxic impact of copper sulfate in lethal and sublethal concentrations was investigated on gill of grass carp, ctenopharynogodon idella . in this investigation, 27 specimens were used as control group and three treatment groups were treated with 2.5 and 5mg/l of copper sulfate. gill samples were collected from each treatment after 96hr and lesions were analyzed by light microscopy. in histop...
