Cusk-eels of the order Ophidiiformes are a morphologically diverse assemblage of eel-like, elongate, posteriorly tapering percomorph fishes that occur worldwide in marine waters, from tropical reef areas to the deep sea. The about 400 extant and fossil species included in the ophidiiform clade are arranged into two main lineages, Bythitoidei and Ophidioidei, based on reproductive biology and the position of the anterior nostrils. The anatomy and phylogenetic relationships of these fishes are… 

Ophidiiform fishes from the Oligocene-early Miocene of Moravia, Czech Republic

The Ophidiiformes has a remarkable ability to adapt to various environments, showing an elongate body with dorsal and anal fins usually continuous and convergent with the caudal fin and thoracic or jugular pelvic fins (if present at all).

A fossil assemblage from the mid–late Maastrichtian of Gavdos Island, Greece, provides insights into the pre-extinction pelagic ichthyofaunas of the Tethys

The global body-fossil record of marine ‘fishes’ from the time interval immediately preceding the Cretaceous–Paleogene Extinction is markedly poor. This deficiency appears to be further exacerbated

Offshore marine actinopterygian assemblages from the Maastrichtian–Paleogene of the Pindos Unit in Eurytania, Greece

This study expands the poor record of body fossils from this critical time interval, especially for smaller sized taxa, while providing a rare, paleogeographically constrained, qualitative glimpse of open-water Tethyan ecosystems from both before and after the extinction event.


The Perarolo taxa document the first Oligocene coral reef fish assemblage known to date, characterized by diminutive putative cryptobenthic fishes, including a single goby (family Gobiidae) and several cardinalfishes of the subfamily Pseudmiinae (family Apogonidae).

First Description and Significance of Cretaceous Teleostean Otoliths (Tar Heel Formation, Campanian) from North Carolina

Fish otoliths (n = 866) from the Tar Heel Formation (Campanian) in North Carolina are the first Cretaceous ear stones to be described from the state and only the fourth study of Atlantic Coastal

First report of Eocene gadiform fishes from the Trans-Urals (Sverdlovsk and Tyumen regions, Russia)

Abstract The recent 2014–2017 controlled excavations carried out in quarries of Sverdlovsk and Tyumen regions, Ural and Western Siberia, are contributing to the knowledge of the middle to late Eocene


The otoliths described here from the Late Santonian of the Eutaw Formation of Alabama, represent one of the earliest association of teleost otoliths known from North America and it is remarkable for

Explosive diversification of marine fishes at the Cretaceous–Palaeogene boundary

This work uses targeted enrichment of >1,000 ultraconserved elements in conjunction with a divergence time analysis to resolve relationships among 120 major acanthomorph lineages and provide a new timescale for acanthomorphic radiation in the wake of the K–Pg boundary.




Abstract Genypterus valdesensis, sp. nov. from the Puerto Madryn Formation in Península Valdés, Argentina is the first fossil ophidiid reported from South America and represents the first well

Occurrence of the Deep-Sea Ophidiid Fish Eretmichthys pinnatus in the Pacific off Japan

The deep-sea ophidiid genus Eretmichthys was established by Garman in 1899 with the type species E. pinnatus characterized by having elongated lower rays of the pectoral fin forming an oar-like structure, and the present material is the first record of this species from Japanese waters.

Saldenioichthys remotus gen. et sp. nov. (Teleostei, Perciformes) and other acanthomorph remains from the Maastrichtian Saldeño Formation (Mendoza, Argentina)

The new perciform taxon from the Saldeno Formation represents one of the oldest members of this group, and due to its peculiar combination of primitive and derived characters, it raises several questions regarding character evolution on this lineage.

The teleost fish Paravinciguerria praecursor Arambourg, 1954 in the Cenomanian of north-eastern Sicily

Skeletal remains of the teleost fish species Paravinciguerria praecursor Arambourg, 1954 are described for the first time from the upper Cenomanian of the Peloritani and Nebrodi Mountains,

The Deep-Sea Anglerfish Genus Acentrophryne (Teleostei, Ceratioidei, Linophrynidae) in the Miocene of California

The analysis of the present and past distribution of the very rare material assigned to Acentrophryne has revealed that it is restricted to the tropical and subtropical sectors of the Eastern Pacific.

Systematics of the Ophidiid Genus Spectrunculus (Teleostei: Ophidiiformes) with Resurrection of S. crassus

The systematics of the abyssal giant cusk-eel genus Spectrunculus was revised, based on the examination of 55 specimens recently collected from the northern Mid-Atlantic Ridge and 32 specimens from earlier collections in the Atlantic and Pacific Oceans, to allow the distinction between two species, requiring the resurrection of S. crassus.

New insights on early evolution of spiny-rayed fishes (Teleostei: Acanthomorpha)

This study provides new insights into the early evolution of the acanthomorphs and the euteleost allies based on the phylogenetic analysis of a newly developed dataset combining nine nuclear and mitochondrial gene markers, and largely agrees with other recent studies based on nuclear loci in inferring an Early Cretaceous origin for the ac anthomorphs followed by a Late Cret Jurassic/Early Paleogene radiation of major lineages.

The Deepsea Ophidiid Fish Genus Lamprogrammus, a Senior Synonym of Bassobythites, with Notes on the Synonymy and Distribution of L. brunswigi

Over the past several years the authors have taken data from a total of 23 specimens identified as Bassobythites, captured in the tropical Atlantic, Indian and Pacific Oceans and ranging in standard length from 139 to 1030mm, including re-examination of published specimens, examination of previously unreported ones, and literature accounts.

New superfamily and three new families of tetraodontiform fishes from the Upper Cretaceous : the earliest and most morphologically primitive plectognaths

The evidence indicates that the Plectocretacicoidea are the morphologically primitive sister group of all other tetraodontiforms (presently known from 55 MYA to Recent).
