Background Fish classifications, as those of most other taxonomic groups, are being
transformed drastically as new molecular phylogenies provide support for natural groups …

Antarctic notothenioid fishes are the classic example of vertebrate adaptive radiation in a
marine environment. Notothenioids diversified from a single common ancestor∼ 22 Mya to …

Spiny-rayed fishes (Acanthomorpha) dominate modern marine habitats and account for
more than a quarter of all living vertebrate species. Previous time-calibrated phylogenies …

Classification of the tremendous diversity of ray-finned fishes (Actinopterygii) began with the
designation of taxonomic groups on the basis of morphological similarity. Starting in the late …

Numerous novel adaptations characterise the radiation of notothenioids, the dominant fish
group in the freezing seas of the Southern Ocean. To improve understanding of the …

Age determination is an important tool in fishery research and management, providing key
data for growth modelling and population dynamics. Knowledge of longevity and growth …

We provide our perspective on the species-level taxonomy of notothenioid fishes, the
dominant component of the fish fauna of Antarctica. There are 140 species in 45 genera, an …

Notothenioids are a clade of∼ 120 species of marine fishes distributed in extreme southern
hemisphere temperate near-shore habitats and in the Southern Ocean surrounding …

We report on the discovery of a remarkable defensive specialization in stonefishes that was
identified during a phylogenetic study of scorpionfishes and their relatives. This newly …

Application of genetic data to species delimitation often builds confidence in delimitations
previously hypothesized using morphological, ecological, and geographic data and …
