The emergence of a new phylogeny of ray-finned fishes at the turn of the twenty-first century
marked a paradigm shift in understanding the evolutionary history of half of living …

The water column of the deep ocean is dark, cold, low in food, and under crushing
pressures, yet it is full of diverse life. Due to its enormous volume, this mesopelagic zone is …

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

Evolutionary innovations are scattered throughout the tree of life, and have allowed the
organisms that possess them to occupy novel adaptive zones. While the impacts of these …

Deep‐sea fishes have long captured our imagination with striking adaptations to life in the
mysterious abyss, raising the possibility that this cold, dark ocean region may be a key hub …

Diversity of feeding mechanisms is a hallmark of reef fishes, but the history of this variation is
not fully understood. Here, we explore the emergence and proliferation of a biting mode of …

Background Seahorses, seadragons, pygmy pipehorses, and pipefishes (Syngnathidae,
Syngnathiformes) are among the most recognizable groups of fishes because of their …

Microplastic (MP) pollution in the marine environment is a worldwide issue. There is growing
concern of consuming MPs through fish, yet the contamination status of fish collected from …

Repeatable, convergent outcomes are prima facie evidence for determinism in evolutionary
processes. Among fishes, well-known examples include microevolutionary habitat …

Colonization of a novel habitat is often followed by phenotypic diversification in the wake of
ecological opportunity. However, some habitats should be inherently more constraining than …
