Abstract
Two specimens of the rare Amarsipa fish, Amarsipus carlsbergi, were collected from Pratas Island in the northern South China Sea. They represent the first record of Taiwanese EEZ and fill the distribution gap in the northwestern Pacific Ocean between Japan (East China Sea) and Vietnam. The two specimens were identified based on their diagnostic characteristics, including no pharyngeal sacs, a pelvic fin well in front of the pectoral fin, a slender body and other morphology. Detailed data and descriptions of these two specimens, including a description of otolith morphology, are provided.

Characterization of six new complete mitochondrial genomes of Chiasmodontidae (Scombriformes, Percomorpha) and considerations about the phylogenetic relationships of the family. Genomics Inform 2023; 21:e10.

Abstract
The fishes of the Chiasmodontidae family, known as swallower fishes, are species adapted to live in deep seas. Several studies have shown the proximity of this family to Tetragonuridae and Amarsipidae. However, the phylogenetic position of this clade related to other Pelagiaria groups remains uncertain even when phylogenomic studies are employed. Since the low number of published mitogenomes, our study aimed to assemble six new mitochondrial genomes of Chiasmodontidae from database libraries to expand the discussion regarding the phylogeny of this group within Scombriformes. As expected, the composition and organization of mitogenomes were stable among the analyzed species, although we detected repetitive sequences in the D-loop of species of the genus Kali not seen in Chiasmodon, Dysalotus, and Pseudoscopelus. Our phylogeny incorporating 51 mitogenomes from several families of Scombriformes, including nine chiasmodontids, recovered interfamilial relationships well established in previous studies, including a clade containing Chiasmodontidae, Amarsipidae, and Tetragonuridae. However, phylogenetic relationships between larger clades remain unclear, with disagreements between different phylogenomic studies. We argue that such inconsistencies are not only due to biases and limitations in the data but mainly to complex biological events in the adaptive irradiation of Scombriformes after the Cretaceous-Paleogene extinction event.

Abstract
Abstract
Extreme body elongation in fishes is a major evolutionary transformation that extends the boundaries of morphological diversity and alters aspects of function, behaviour and ecology. Prior studies have identified features of the cranial and axial skeleton that characterize elongate fishes, but a lack of detailed reconstructions of anatomical evolution has limited inferences about factors that underlie major shifts in body shape. In this study, we fitted multi-peak adaptive (Ornstein–Uhlenbeck) evolutionary models to species body shape and anatomical dimensions in Pelagiaria, a radiation of open-ocean fishes whose species span a continuum from deep bodied to highly elongate. We inferred an ancestral fusiform adaptive peak that is retained by several major pelagiarian lineages (e.g. Scombridae) and found robust support for multiple transitions to deep-bodied optima (in the families Stromateidae, Bramidae and Caristiidae) and elongate-bodied optima (within Trichiuroidei), including two instances of sequential shifts towards increasingly elongate optima that followed distinct paths of anatomical evolution. Within Trichiuridae, initial increases in head length and the number of vertebrae were followed by changes in head and vertebral shape. Within an elongate-bodied subclade of taxa traditionally identified as ‘gempylids’, changes in head and vertebral shape and in the number of precaudal vertebrae preceded an increase in the number of caudal vertebrae. Altogether, this mosaic of anatomical peak shifts suggests that body shape transformations were associated with differing selective demands and developmental changes.

Abstract
Abstract
More than half the ray-finned fishes and about one-quarter of all living vertebrates belong to Percomorphacea. Among its 30 orders, Stromateiformes encompass 77 species in 16 genera and six families. Stromateiform monophyly has never been tested using morphology, and it has been rejected by molecular analyses. This comprehensive revision of Stromateiformes includes all its valid genera of all percomorph families previously aligned with the order. We sampled 207 phenotypic characters in 66 terminal taxa representing 14 orders and 46 acanthopterygian families. This dataset significantly surpasses all previous phenotype-based phylogenies of Stromateiformes, which analysed only a fraction of these characters. Stromateiformes is recovered as monophyletic, supported by eight unequivocal synapomorphies. Amarsipidae is the sister group of all other Stromateiformes (= Stromateoidei). Centrolophidae is paraphyletic, with three of its genera allocated into an early-diverging clade and the other four appearing as successive sister groups to a lineage containing the remaining stromateiforms. All other stromateoid families are monophyletic, with the following cladistic arrangement: (Nomeidae (Stromateidae (Tetragonuridae, Ariommatidae))). Our analysis convincingly refutes recent molecular phylogenetic interpretations that fail to recover a monophyletic Stromateiformes. These findings call into question large-scale conclusions of percomorph relationships and trait evolution based solely on molecular data.
