Mitochondrial Genomes of Six <i>Discogobio</i> Species (Teleostei, Cyprinidae) and Their Phylogenetic Analysis. [PDF]
In this study, we sequenced and analyzed the complete mitochondrial genome sequences of six Discogobio species by conventional overlapping PCR and Sanger sequencing. Additionally, we investigated the phylogenetic history of the Discogobio genus. ABSTRACT Discogobio is an important small freshwater economic fish in Southwestern China.

Life in Extreme Conditions: Diet and Condition of the Extremophile Fish <i>Aphanius almiriensis</i> (Teleostei: Cyprinodontiformes) in a Thermal Rheocrene Spring. [PDF]
This study aims to answer some questions about the bioecological traits of an extremophile fish Aphanius almiriensis in order to understand how it can survive and colonize the extreme habitat conditions. To this end, some bioecological characteristics—condition, diet, and feeding strategy—of A. almiriensis inhabiting the Tuzla thermal spring, which has

Blood Anlage in Teleostei [PDF]
THE mode of origin of blood in Teleosts is considered to represent an exception in the development of Vertebrates. Since the observations of Swaen and Brachet1 the intermediate cell mass of Oellacher is considered to be the earliest primordium of blood and blood-vessels.

Sperm of Doradidae (Teleostei: Siluriformes)
Spermatic characteristics were studied in 10 species representing several distinct groups within the catfish family Doradidae. Interestingly, different types of spermatogenesis, spermiogenesis and spermatozoa are correlated with intrafamilial groups previously proposed for Doradidae.

Sperm phylogeny of Characidae (Teleostei, Characiformes)
AbstractThe phylogeny of the very diverse Neotropical fish family Characidae has been the subject of several recent contributions based on morphological characters, molecular data or both in combined analyses. In cases of conflict between these kinds of data, resolution by combined analyses most often tends to agree with the molecular evidence, given ...

Evolution of the locomotory system in eels (Teleostei: Elopomorpha) [PDF]
Living anguilliform eels represent a distinct clade of elongated teleostean fishes inhabiting a wide range of habitats. Locomotion of these fishes is highly influenced by the elongated body shape, the anatomy of the vertebral column, and the corresponding soft tissues represented by the musculotendinous system.

Genomics and mapping of Teleostei (bony fish) [PDF]
AbstractUntil recently, the Human Genome Project held centre stage in the press releases concerning sequencing programmes. However, in October 2001, it was announced that the Japanese puffer fish (Takifugu rubripes, Fugu) was the second vertebrate organism to be sequenced to draft quality. Briefly, the spotlight was on fish genomes. There are currently
