“…Reproductive isolation between G. cinereus and G. simillimus has resulted in morphological variation that can be quantified by analysing the shape of the bodies, urohyal bones or sagittae otoliths, which are important for taxonomic purposes (Arratia & Schultze, ; Baremore & Bethea, ; Chollet‐Villalpando et al, ; De La Cruz‐Agüero et al, ; Jawad, Khahe‐Jahromi, Teimori, Mehraban, & Esmaeili, ; Nolf, ; Reichenbacher, Sienknecht, Kuchenhoff, & Fenske, ). The discriminant power of body shape was higher than otolith and urohyal shape.…”

For many years in America, many authors have considered that the Gerres genus contained a single species, the yellowfin mojarra Gerres cinereus (Walbaum, 1792); however, others have recognized two species in this genus in the Neotropics. In this study, specimens of G. cinereus (sensu lato) caught throughout its geographic range on both coasts of America were compared for the first time to analyse divergence among the sampled populations. A genetic analysis based on DNA sequences from three mitochondrial genes and one nuclear gene revealed a clear separation of two clades, one in the Pacific and one in the Atlantic. Geometric morphometric differences, based on body shape, sagittae otoliths and urohyal bone features, were significant between the two groups, including separation by an accurate classification a posteriori by a canonical variate analysis (CVA) > 82% in all data sets (overall mean >91%). Integration of the results of these approaches indicates that there is sufficient evidence to support species status for Gerres simillimus Regan, 1907, and it should be considered a valid species in the neotropical Pacific.

“…Afterward, the urohyal bones were stored in small tubes, cataloged and deposited in the Zoological Museum of Shahid Bahonar University of Kerman (ZM-SBUK). The lateral view of the urohyal bones was photographed from the left side by using a Dino-Lite Camera mounted on a stereomicroscope because the lateral view of urohyal bone is an important character for species differentiation (Jawad et al, 2017). The terminology introduced in Chollet-Villalpando et al (2014) was used to describe the urohyal bone morphology (Fig.…”

“…1). Urohyal maximum length (anterior to posterior distance, UL) and urohyal maximum depth (dorsal to ventral distance, UD) of the urohyal bones were measured following Jawad et al (2017). Accordingly, the E index (E = UD/UL %) was calculated to determine the relationship between the shape of the urohyal bone among the seven gobies species (Jaramillo et al, 2014).…”

“…The urohyal bone is not easily digested in the stomach of predators; therefore, it has been used in trophic studies of the aquatic-and aquatic related animals such as fish, seals and birds (Hansel et al, 1988;Pierce et al, 1991;Johdal et al, 2001;Tombari et al, 2010). Moreover, owing to its morphological variability, the urohyal bone has been used extensively in fish taxonomy for species identification and even the discrimination among the genera and families (e.g., Kusaka, 1974;Pierce et al, 1991;Esmaeili & Teimori, 2006;Jawad et al, 2017;Teimori et al, 2018).…”

Shape variation and functional adaptation in a structure involved in the feeding system of gobiid fishes

et al. 2020

Fish are observed in different aquatic environments, including freshwater, marine and also intertidal zones. It is suggested that the urohyal bone is involved in the feeding function of fish. Information about the urohyal bone in different fish groups, including gobiids is rare. In the present study, changes in the shape of the urohyal bone were studied in seven gobiid fish from the intertidal environments of the Persian Gulf and the Gulf of Oman by applying shape analysis and geometric morphometric analyses. The results revealed that the shape of the urohyal bone in each species was distinct, which is almost consistent with their phylogenetic relationships. Periophthalmus waltoni inhabits often terrestrial habitats and requires a system to obtain food. The specific shape of the urohyal bone in this species probably results from a functional adaptation to obtain food from the terrestrial environment. Moreover, our results indicated that the shape variation in the urohyal bone of the studied species is linked to their feeding because the calculation of E index categorized those species with similar feeding regimes into one group. In conclusion, we assumed that the urohyal shape variation in the studied gobiid species is the result of compatibility to the various feeding regimes, and it is likely controlled by genetic factors. Furthermore, the results support the usefulness of the urohyal bone morphology in differentiating the studied gobiid species and highlighting the taxonomic value of the urohyal bone.

“…Sci., 19/2, 2018, 356-365 357 The urohyal bone is considered as synapomorphy for the members of teleost fishes (De Pinna, 1996). Further studies indicated that morphological features of the urohyal bone can be used to discriminate fish families, genera and even species (Arratia & Schultze, 1990;Jawad et al, 2016), and that urohyal bone has taxonomic significance (Kusaka, 1974;Esmaeili & Teimori, 2006). Therefore, it can be hypothesized that urohyal bone contains sufficient data to disclose taxonomic and even phylogenetic relationships among the fishes.…”

Among the skeletal elements in fishes, the urohyal bone which lies in the lower part of the head - the central part of the mandibular skeleton- has proved to be of special significance in fish systematics. The urohyal bone is considered to be a synapomorphic structure in teleostean fish. The urohyal bone of six brackish water Aphanius species (i.e., Aphanius hormuzensis, A. stoliczkanus, A. furcatus, A. ginaonis, A. mento, A. sirhani) was compared using morphological description and linear measurements to explore the effectiveness of urohyal bone morphology in the separation of the Aphanius species. Description of the urohyal bones and their morphological variation allowed identification of the A. furcatus, A. mento and A. sirhani from their relatives. Moreover, the UH.UL separates significantly A. dispar and A. ginaonis, and the MH.UL discriminates significantly A. mento from others studied relatives. Discriminant function analysis (DFA) separated the studied species with high classification success (overall mean 94.7%). These results suggest the power of urohyal bone morphology in separating of the Aphanius species analyzed, and highlighting the taxonomic value of the urohyal bone. By considering the phylogenetic relationships among the studied species, it can be concluded that the observed variation in their urohyal morphology is largely consistent with their phylogeny. This indicated that at least some morphological characters in the shape of urohyal bone in Aphanius are encoded probably by genetic factors, which can be used for species discrimination.
