Asian pangasiids—an emerging problem for European inland waters? Systematic and parasitological aspects [PDF]

Acta Ichthyologica et Piscatoria, 2009
Background. Asian pangasiids (Actinopterygii: Siluriformes: Pangasiidae), commonly referred to as “panga”, have recently became an important item on the European fish markets.

The dental plate on bichir pectoral fins: A unique dermal skeletal element bearing individual odontodes with tooth‐like replacement

Journal of Anatomy, EarlyView.
Pectoral fins of bichirs encompass the so‐called dental plates – unique dermal skeletal elements with individual odontodes identical to the oral teeth. Abstract The dermal skeleton appeared early in vertebrate evolution in the form of mineralized skin denticles composed of tooth‐like units—odontodes.

Biological aspects of an interesting fossil fish:Paramblypterus duvernoyi (Amblypteridae, Actinopterygii) [PDF]

Mitteilungen aus dem Museum für Naturkunde in Berlin. Geowissenschaftliche Reihe, 2001
Based on three-dimensional models of the skull and body of Paramblypterus duvernoyi, function of the feeding apparatus and potential of locomotion are interpreted. Compared to most other lower actinopterygians, certain modified features regarding the suspensory apparatus, snout bones, gape, dermohyal and suborbital region, and palaloquadrate-maxillary ...

The lower jaw of Devonian ray‐finned fishes (Actinopterygii): Anatomy, relationships, and functional morphology

The Anatomical Record, Volume 309, Issue 3, Page 550-602, March 2026.
Abstract Actinopterygii is a major extant vertebrate group, but limited data are available for its earliest members. Here we investigate the morphology of Devonian actinopterygians, focusing on the lower jaw. We use X‐ray computed tomography (XCT) to provide comprehensive descriptions of the mandibles of 19 species, which span the whole of the Devonian

Phylogenetic Classification of Living and Fossil Ray-Finned Fishes (Actinopterygii)

Bulletin of the Peabody Museum of Natural History
Classification of the tremendous diversity of ray-finned fishes (Actinopterygii) began with the designation of taxonomic groups based on morphological similarity. Starting in the late 1960s morphological phylogenetics became the basis for the classification of Actinopterygii but failed to resolve many relationships, particularly among lineages within ...

Comprehensive phylogeny of ray-finned fishes (Actinopterygii) based on transcriptomic and genomic data [PDF]

Proceedings of the National Academy of Sciences, 2018
Significance Ray-finned fishes form the largest and most diverse group of vertebrates. Establishing their phylogenetic relationships is a critical step to explaining their diversity. We compiled the largest comparative genomic database of fishes that provides genome-scale support for previous phylogenetic results and used it to resolve ...

FishPIE: A universal phylogenetically informative exon markers set for ray-finned fishes

iScience, 2022
Summary: Understanding the evolutionary history of the highly diverse ray-finned fishes has been challenging, and the development of more universal primers for phylogenetic analyses may help overcoming these challenges. We developed FishPIE, a nested PCR

Marine water environmental DNA metabarcoding provides a comprehensive fish diversity assessment and reveals spatial patterns in a large oceanic area

Ecology and Evolution, 2020
Current methods for monitoring marine fish (including bony fishes and elasmobranchs) diversity mostly rely on trawling surveys, which are invasive, costly, and time‐consuming.

Diversity and Spatiotemporal Distribution of Fish in a Highland Lake in China Based on Environmental DNA Metabarcoding

Ecology and Evolution, Volume 16, Issue 2, February 2026.
We analyzed water samples from different seasons and locations in Erhai Lake to determine whether eDNA barcoding can effectively show the diversity of fish in such lakes. In the manuscript, we discuss our findings regarding the range of species found, their spatiotemporal distribution, and whether eDNA barcoding gave similar results to traditional ...
