SYSTEMATIC REVISION OF THE GENERA OF PANGASIIDAE (SILURIFORMES, OSTARIOPHYSI)

open access: yesIndonesian Aquaculture Journal, 2008
The family Pangasiidae belongs to the suborder Siluroidei, order Siluriformes, and suborder Ostariophysi. Since the groups were established as Pangasiini Bleeker, 1858; its content and classification have been greatly changed. Judging from the literature, the main constraint to cultivate wild species and to optimize the production of cultured species ...

Ossification of the cranium of Inpaichthys kerri (Characiformes: Acestrorhamphidae) with discussion of paedomorphic traits in the genus

open access: yesJournal of Anatomy, Volume 248, Issue 5, Page 806-829, May 2026.
In this study, we present a detailed description of the cranial development of Inpaichthys kerri (Characiformes: Acestrorhamphidae), highlighting important topics such as pedomorphic characters and their relationship with ontogeny and phylogeny, as well as ossification sequences unique to the species. Abstract The study of development provides valuable

Enigmatic Nodal and Lefty gene repertoire discrepancy: Latent evolutionary history revealed by vertebrate‐wide phylogeny

open access: yesDevelopmental Dynamics, Volume 254, Issue 8, Page 887-901, August 2025.
Abstract Homology in vertebrate body plans is traditionally ascribed to the high‐level conservation of regulatory components within the genetic programs governing them, particularly during the “phylotypic stage.” However, advancements in embryology and molecular phylogeny have unveiled the dynamic nature of gene repertoires responsible for early ...

External Morphology of Leporinus oliveirai (Characiformes: Anostomidae) During Early Life Stages

open access: yesJournal of Morphology, Volume 286, Issue 7, July 2025.
Herein, we describe the early development of Leporinus oliveirai, a recently described species, documenting its external morphology with photographs and illustrations. The ontogeny of L. oliveirai is compared with other anostomids and developmental patterns are described for the family.

Fishes from the Upper Cretaceous Prince Creek Formation, North Slope of Alaska, and their palaeobiogeographical significance

open access: yesPapers in Palaeontology, Volume 11, Issue 3, May/June 2025.
Abstract The Upper Cretaceous Prince Creek Formation (PCF) of northern Alaska offers a unique glimpse into northern high‐latitude, non‐marine vertebrate assemblages, providing critical data on polar ecosystems during the late Campanian (c. 73 Ma).

Molecular phylogenetics, a new classification, and a new genus of the Neotropical fish family Anostomidae (Teleostei: Characiformes) [PDF]

open access: yesNeotropical Ichthyology
Phylogenetic reconstruction of the Neotropical freshwater fish family Anostomidae using multilocus sequence data from 97 species supports the recognition of three subfamilies: Leporellinae with one genus, Anostominae with six genera, and Leporininae with
