Abstract
Climate changes have altered biodiversity and ultimately induced community changes that have threatened the survival of certain aquatic organisms such as fish species. Obtaining biological and genetic information on endangered fish species is critical for ecological population management. Thamnaconus multilineatus, registered as an endangered species by the IUCN in 2019, is a Data Deficient (DD) species with a remarkably small number of habitats worldwide and no known information other than its habitat and external form. In this study, we characterized the external and osteological morphology of a T. multilineatus specimen collected from eastern Jeju Island, South Korea, in 2020. We also investigated the phylogenetic relationships among related fish species through complete mitochondrial DNA (mtDNA) analysis of the T. multilineatus specimen. The external and skeletal characteristics of T. multilineatus were similar to those of previous reports describing other fish of the genus Thamnaconus, making it difficult to classify T. multilineatus as a similar species based only on morphological characteristics. As a result of analyzing the complete mtDNA of T. multilineatus, the length of the mtDNA was determined to be 16,435 bp, and the mitochondrial genome was found to have 37 CDCs, including 13 PCGs, 22 tRNAs, and 2 rRNAs. In the phylogenetic analysis within the suborder Balistoidei, T. multilineatus mtDNA formed a cluster with fish of the genus Thamnaconus. This study is the first to report on the skeletal structure and complete mtDNA of T. multilineatus. Since the current research on T. multilineatus has only been reported on morphology, the results of this study will be utilized as important information for the management and restoration of T. multilineatus as an endangered species and significant fishery resource.

Abstract
The long PCR and primer walking methods were applied for obtaining the complete mitochondrial genome of the tessellated leatherjacket Thamnaconus tessellatus. The complete mitochondrial genome was 16,437 bp in length and contained 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes, an origin of L-strand replication and a control region. The arrangements and characteristics of these segments shared common features with other teleosts. Extended termination associated sequence domain (TAS, cTAS), central conserved sequence block domain (CSB-F, CSB-E, CSB-D) and conserved sequence block domain (CSB-1, CSB-2, CSB-3) were identified in the control region.

Abstract
Tetraodontiform fishes represent one of the most peculiar radiations of teleost fishes. In spite of this, we do not currently have a consensus on the phylogenetic relationships among the major tetraodontiform lineages, with different morphological and molecular datasets all supporting contrasting relationships. In this paper we present the results of the analysis of tetraodontiform interrelationships based on two mitochondrial and 20 nuclear loci for 40 species of tetraodontiforms (representing all of the 10 currently recognized families), as well as three outgroups. Bayesian and maximum likelihood analyses of the concatenated dataset (18,682 nucleotides) strongly support novel relationships among the major tetraodontiform lineages. Our results recover two large clades already found in mitogenomic analyses (although the position of triacanthids differ), while they strongly conflict with hypotheses of tetraodontiform relationships inferred by previous studies based on morphology, as well as studies of higher-level teleost relationships based on nuclear loci, which included multiple tetraodontiform lineages. A parsimony gene-tree, species-tree analysis recovers relationships that are mostly congruent with the analyses of the concatenated dataset, with the significant exception of the position of the pufferfishes+porcupine fishes clade. Our findings suggest that while the phylogenetic placement of some tetraodontiform lineages (triacanthids, molids) remains problematic even after sequencing 22 loci, an overall molecular consensus is beginning to emerge regarding the existence of several major clades. This new hypothesis will require a re-evaluation of the phylogenetic usefulness of several morphological features, such as the fusion of several jaw bones into a parrot-like beak, or the reduction and loss of some of the fins, which may have occurred independently more times than previously thought.

Abstract
Innovations in locomotor morphology have been invoked as important drivers of vertebrate diversification, although the influence of novel locomotion strategies on marine fish diversification remains largely unexplored. Using triggerfish as a case study, we determine whether the evolution of the distinctive synchronization of enlarged dorsal and anal fins that triggerfish use to swim may have catalyzed the ecological diversification of the group. By adopting a comparative phylogenetic approach to quantify median fin and body shape integration and to assess the tempo of functional and morphological evolution in locomotor traits, we find that: (1) functional and morphological components of the locomotive system exhibit a strong signal of correlated evolution; (2) triggerfish partitioned locomotor morphological and functional spaces early in their history; and (3) there is no strong evidence that a pulse of lineage diversification accompanied the major episode of phenotypic diversification. Together these findings suggest that the acquisition of a distinctive mode of locomotion drove an early radiation of shape and function in triggerfish, but not an early radiation of species.

Abstract
The pelvic fins of teleosts are paired appendages that are considered to be homologous to the hind limbs of tetrapods. Because they are less important for swimming, their morphology and function can be flexibly modified, and such modifications have probably facilitated the adaptations of teleosts to various environments. Recently, among these modifications, pelvic-fin loss has gained attention in evolutionary developmental biology. Pelvic-fin loss, however, has only been investigated in a few model species, and various biological aspects of pelvic fins in teleosts in general remain poorly understood. This review summarizes the current state of knowledge regarding pelvic fins, such as their structure, function and evolution, to elucidate their contribution to the considerable diversity of teleosts. This information could be invaluable for future investigations into various aspects of pelvic fins, which will provide clues to understanding the evolution, diversity and adaptations of teleosts.
