“…Gunnellichthys-lineage was resolved to form a complete monophyletic group. Aphia-lineage showed a sister relationship with Valenciennea-lineage (see also Thacker 2015;McCraney et al 2020). Although Gobiopsis-lineage was resolved as a monophyletic group in previous reports (Thacker 2009;Agorreta et al 2013), Cryptocentrus-lineage was clustered with Gobiopsis-lineage in our results.…”

“…Our analyses revealed that Oxudercidae could be divided into five sub-clades (see also Thacker 2015;McCraney et al 2020), though the Acanthogobius-lineage failed to form a monophyletic clustering. Rhinogobius and Stenogobius were phylogenetically close with each other in previous studies (Parenti and Thomas 1998;Wang et al 2001), which is clearly contrast to our results.…”

“…As molecular tools were applied, there have been claims that Gobiidae could be divided into two monophyletic families, Gobiidae and Oxudercidae (Thacker 2003;Agorreta et al 2013;Nelson et al 2016). Recent studies further assigned these two families into 19 lineages, five from Oxudercidae and 14 from Gobiidae (Thacker and Roje 2011;Thacker 2013;Agorreta et al 2013;McCraney et al 2020). However, many Oxudercidae species were not considered in establishing this lineage system.…”

Gobioidei is one of the largest vertebrate taxa with over 2000 species observed around the globe. The largest group in Gobioidei is gobies that had been classified as one family, Gobiidae, based on morphological features. Molecular phylogenetic studies revealed that gobies consisted of two monophyletic families, Gobiidae and Oxudercidae, in which 19 lineages have been proposed, despite some claims arisen about the relationship among these lineages or species. We analyzed 58 Gobioidei species, including 45 East Asian oxudercids, based on 12S rRNA sequences to reconstruct the spatiotemporal diversification history of gobies. Our analysis yielded the results compatible with the previous reports in a large framework. The common ancestor of Gobiidae and Oxudercidae were estimated to appear at 38.66 Mya. Genus-level splits occurred in Gobiidae and Oxudercidae predominantly at Miocene and late Miocene to early Pleistocene, respectively. Gobies have likely originated in many parts of the northern and western Pacific Ocean, of which a large proportion of Oxudercidae have adapted to various environments in the North Pacific.

“…The other form of climbing, inching, is restricted to the genus Sicyopterus and entails individuals climbing rectilinearly up waterfalls by alternating attachment of the pelvic disc and a second sucker formed from the mouth (Cullen et al, 2013). Based on available phylogenetic data (McCraney et al, 2020; Taillebois et al, 2014), waterfall climbing behaviors appear to have a single evolutionary origin, and the inching lineage appears to have evolved from powerburst climbing ancestors (Figure 1).…”

Bendy to the bone: Links between vertebral morphology and waterfall climbing in amphidromous gobioid fishes

et al. 2021

Locomotor force production imposes strong demands on organismal form. Thus, the evolution of novel locomotor modes is often associated with morphological adaptations that help to meet those demands. In the goby lineage of fishes, most species are marine and use their fused pelvic fins to facilitate station holding in wave‐swept environments. However, several groups of gobies have evolved an amphidromous lifecycle, in which larvae develop in the ocean but juveniles migrate to freshwater for their adult phase. In many of these species, the pelvic fins have been co‐opted to aid in climbing waterfalls during upstream migrations to adult habitats. During horizontal swimming, forces are produced by axial musculature pulling on the vertebral column. However, during vertical climbing, gravity also exerts forces along the length of the vertebral column. In this study, we searched for novel aspects of vertebral column form that might be associated with the distinctive locomotor strategies of climbing gobies. We predicted that stiffness would vary along the length of the vertebral column due to competing demands for stability of the suction disk anteriorly and flexibility for axial thrust production posteriorly. We also predicted that derived, climbing goby species would require stiffer backbones to aid in vertical thrust production compared to non‐climbing species. To test these predictions, we used microcomputed tomography scans to compare vertebral anatomy (centrum length, centrum width, and intervertebral space) along the vertebral column for five gobioid species that differ in climbing ability. Our results support our second prediction, that gobies are more flexible in the posterior portion of the body. However, the main variation in vertebral column form associated with climbing ability was the presence of larger intervertebral spaces in Sicyopterus stimpsoni, a species that uses a distinctive inching behavior to climb. These results build on past kinematic studies of goby climbing performance and lend insights into how the underlying vertebral structure of these fishes may enable their novel locomotion.

Rhyacichthys aspro is a “basal” taxon in the Suborder Gobioidei of the teleost order Gobiiformes. We provide detailed descriptions of the reproductive morphology of adult males and females to assess the diagnostic reproductive morphological characters of this speciose clade of bony fishes. Female R. aspro are asynchronous spawners: they are able to spawn more than once in a breeding season. Oocytes are inferred to have short attachment filaments. A conspicuous feature of the external anatomy of the reproductive system (RSy) of female R. aspro is an ornate fimbriate pad upon which the urogenital papilla rests. The male reproductive system is characterized by an intralobar collection system in both the testicular and secretory lobes, termed the “sperm‐collecting canal” and “milt‐collecting canal,” respectively. These may provide additional storage for sperm and milt. The spermatogenic lobe, or testis, is that portion of the male gobioid RSy comprising seminiferous lobules and separate from other RSy components. The secretory lobe is that portion of the male gobioid reproductive system that consists of secretory lobules and is separated from other components of the male RSy. The secretory lobe has also been called, in English, the sperm‐duct gland, accessory gonadal structure, or seminal vesicle, and is endorsed as a synapomorphy of gobioid fishes.
