Motivation Global freshwater fish biodiversity and the responses of fishes to global changes have been explored intensively using taxonomic data, whereas functional aspects remain understudied owing lack knowledge for most species. To fill this gap, we compiled morphological traits related locomotion feeding world fauna based on pictures scientific drawings available from literature. Main types...

Like most ray-finned fishes (Actinopterygii), pipefishes (Syngnathoidei) feed by suction. Most pipefishes reach their prey by a rapid dorso-rotation of the head. In the present study, we analysed the feeding kinematics of the razor fish, Centriscus scutatus, and of the greater pipefish, Syngnathus acus in detail. We found capture times of as little as 4-6ms for C. scutatus and 6-8ms for S. acus...

The Actinopterygii (ray-finned fishes) is the largest and most diverse vertebrate group, but little is agreed about the timing of its early evolution. Estimates using mitochondrial genomic data suggest that the major actinopterygian clades are much older than divergence dates implied by fossils. Here, the timing of the evolutionary origins of these clades is reinvestigated using morphological, ...

Body length–weight (L–W) relationships of 123 fish species (122 Actinopterygii and 1 Elasmobranchii) were studied from 10 218 individuals caught around Réunion Island 2000 to 2021. All species, except for 4 with a very small number limited length range, showed significant relationship between total weight. For 52 the data body becoming more elongated (i.e. b < 3.0) over their lifespan, while 63...

An invasive alien species American bullfrog (hereafter, ‘bullfrog') is found in freshwater lakes Onuma Quasi-National Park, Hokkaido, Japan. Bullfrog commonly feeds on red swamp crayfish many areas. However, has not been confirmed Komuna Lake, Park. The purpose of this study to examine the trend predation native biomes areas without presence. We detected dietary composition bullfrogs. stomach c...

a detailed description of the osteological structure of kiabi loach ( oxynoemacheilus kiabii ), a recently described endemic species caught from gamasiab river, iran, is provided. seven specimens were collected by electrofishing in june 2013 and cleared and stained and its osteological structures were described. the results showed that o. kiabii can be distinguished from other members of the ge...
