Abstract The 27 extant species of the family Sphyraenidae represent one of the major groups of piscivorous teleost fishes in tropical and subtropical marine waters. In spite of their ecological importance, currently, no phylogenetic hypothesis is available for this group, and we do not know the tempo of evolution of this clade. In this study, we used a supermatrix approach to assemble a dataset of three mitochondrial loci for 20 sphyraenid species, and time-calibrated this new phylogeny. Our… 

Chromosomal evolution in large pelagic oceanic apex predators, the barracudas (Sphyraenidae, Percomorpha).

The karyotypic patterns of the Sphyraena genus contrast with the current phylogenetic relationships proposed for this group, showing by themselves to be distinct among closely related species, and similar among less related ones.

Large-bodied sabre-toothed anchovies reveal unanticipated ecological diversity in early Palaeogene teleosts

The identification of large-bodied, piscivorous anchovies contributes to an emerging picture of a phylogenetically diverse guild of predatory ray-finned fishes in early Palaeogene marine settings, which include completely extinct lineages alongside members of modern marine groups and taxa that are today restricted to freshwater or deep-sea environments.

Taxonomy and biostratigraphy of the elasmobranchs and bony fishes (Chondrichthyes and Osteichthyes) of the lower-to-middle Eocene (Ypresian to Bartonian) Claiborne Group in Alabama, USA, including an analysis of otoliths

The Tallahatta Formation, Lisbon Formation, and Gosport Sand are the three lithostratigraphic units that make up the lower-to-middle Eocene Claiborne Group. In Alabama, these marine units are among

Comparisons with other marine taxa that show hypertrophied symphysial teeth are made in order to assess the taxonomic value of symphysIAL teeth as diagnostic structures of value in studies of isolated sphyraenid specimens.

The Phylogeny of Carangiform Fishes: Morphological and Genomic Investigations of a New Fish Clade

Combined analyses of new and previously identified discrete morphological characters and new andPreviously published genome-scale data are performed to characterize the evolutionary history and anatomical variation within this clade of fishes.

An exceptionally preserved Eocene shark and the rise of modern predator–prey interactions in the coral reef food web

The modern trophic association between higher-degree consumers (Galeorhinus and Sphyraena) has a counterpart in the Eocene Bolca, just as Bolca and the Great Barrier Reef show parallels among teleost primary consumers.

Upper Oligocene marine fishes from nearshore deposits of the Central Paratethys (Máriahalom, Hungary)

A rich and diverse ichthyofauna is described from the upper Oligocene (Egerian) sands of Máriahalom, Hungary. The site is dominated by brackish molluscs that are preserved together with rare marine

Phylogenetic perspectives on reef fish functional traits

It is argued that the combination of a phylogenetic and a functional approach will improve the understanding of the mechanisms of species assembly in extraordinarily rich coral reef communities.



First molecular scombrid timetree (Percomorpha: Scombridae) shows recent radiation of tunas following invasion of pelagic habitat

The result of the first quantitative macroevolutionary study of scombrid evolution is presented, showing how the most significant radiation within scombrids has taken place since the Late Miocene in tunas, possibly triggered by a transition from pelagic-neritic to Pelagic-oceanic habitats, and matched by a dramatic increase in body size.

First molecular timetree of billfishes (Istiophoriformes: Acanthomorpha) shows a Late Miocene radiation of marlins and allies

A time-calibrated molecular hypothesis of the timing of billfish evolution is generated using 10 loci and utilizing the rich fossil record dating back to the Early Eocene infers a Late Cretaceous origin for the istiophoriforms.

Evolutionary Origin of the Scombridae (Tunas and Mackerels): Members of a Paleogene Adaptive Radiation with 14 Other Pelagic Fish Families

A clade of open-ocean fishes containing Scombridae is named “Pelagia” in reference to the common habitat preference that links the 15 families, suggesting that they represent a previously undetected adaptive radiation in the pelagic realm.

Phylogeny and tempo of diversification in the superradiation of spiny-rayed fishes

Analysis of clade-specific shifts in diversification rates reveal that the hyperdiversity of living acanthomorphs is highlighted by several rapidly radiating lineages including tunas, gobies, blennies, snailfishes, and Afro-American cichlids, indicating there is no single explanation for the success of acanthomorphics.

Molecular evidence for the taxonomic status of three species of the Sphyraena obtusata group (Perciformes: Sphyraenidae) from East Asia

These findings fully supported the taxonomic status of these species, recently elucidated by detailed morphological comparisons, and the S. obtusata group formed a strongly supported clade against the four other congeneric species.
