“…This behaviour is characterized by the expulsion of water from the mantle cavity while the valves are closed, allowing the animal to propel forward with the ventral‐edge leading (Manuel & Dadswell, ; Cheng et al ., ). The biomechanic properties of gliding have been extensively studied, and we have a good understanding of the parameters important to maximize performance (Morton, ; Joll, ; Hayami, ; Millward & Whyte, ; Manuel & Dadswell, ; Cheng et al ., ; Ansell et al ., ; Himmelman et al ., ; Guderley & Tremblay, ; Tremblay et al ., ). Intriguingly, some measurements of gliding kinematics vary within the ecomorph (Caddy, ; Morton, ; Joll, ; Ansell et al ., ; Mason et al ., ), suggesting that there are differences among the functional components of locomotion (see Results).…”

An important question in evolutionary biology is how often, and to what extent, do similar ecologies elicit distantly related taxa to evolve towards the same phenotype? In some scenarios, the repeated evolution of particular phenotypes may be expected, for instance when species are exposed to common selective forces that result from strong functional demands. In bivalved scallops (Pectinidae), some species exhibit a distinct swimming behaviour (gliding), which requires specific biomechanical attributes to generate lift and reduce drag during locomotive events. Further, a phylogenetic analysis revealed that gliding behaviour has independently evolved at least four times, which raises the question as to whether these independent lineages have also converged on a similar phenotype. Here, we test the hypothesis that gliding scallops display shell shape convergence using a combination of geometric morphometrics and phylogenetic comparative methods that evaluate patterns of multivariate trait evolution. Our findings reveal that the gliding species display less morphological disparity and significant evolutionary convergence in morphospace, relative to expectations under a neutral model of Brownian motion for evolutionary phenotypic change. Intriguingly, the phylomorphospace patterns indicate that gliding lineages follow similar evolutionary trajectories to not one, but two regions of morphological space, and subsequent analyses identified significant differences in their biomechanical parameters, suggesting that these two groups of scallops accomplish gliding in different ways. Thus, whereas there is a clear gliding morphotype that has evolved convergently across the phylogeny, functionally distinct morphological subforms are apparent, suggesting that there may be two optima for the gliding phenotype in the Pectinidae.

“…Pectinidae is an ideal model to study the evolution of complex traits due to the number and biological diversity of extant species, the link between shell morphology and habitat use (Stanley, 1970), and their high preservability in the paleontological record (Valentine et al, 2006). Researchers have investigated the evolution of traits such as shell shape (Serb et al, 2011(Serb et al, , 2017Sherratt et al, 2016;Stanley, 1970), behavior (Alejandrino et al, 2011), swimming mechanics (Guderley and Tremblay, 2013;Hayami, 1991;Millward and Whyte, 1992;Tremblay et al, 2015), and phototransduction (Faggionato and Serb, 2017;Gomez et al, 2011;Kingston et al, 2015;Porath-Krause et al, 2016;Serb et al, 2013). One compelling set of phenotypes is the complex sensory systems, including eyes, found in this family (Audino et al, 2015a(Audino et al, , 2015b(Audino et al, , 2015cLand, 1965;Speiser et al, 2011Speiser and Johnsen, 2008).…”

Scallops (Pectinidae) are one of the most diverse families of bivalves and have been a model system in evolutionary biology. However, in order to understand phenotypic evolution, the Pectinidae needs to be placed in a deeper phylogenetic framework within the superfamily Pectinoidea. We reconstructed a molecular phylogeny for 60 species from four of the five extant families within the Pectinoidea using a five gene dataset (12S, 16S, 18S, 28S rRNAs and histone H3). Our analyses give consistent support for the non-monophyly of the Propeamussiidae, with a subset of species as the sister group to the Pectinidae, the Propeamussiidae type species as sister to the Spondylidae, and the majority of propeamussiid taxa sister to the Spondylidae + Pr. dalli. This topology represents a previously undescribed relationship of pectinoidean families. Our results suggest a single origin for eyes within the superfamily and likely multiple instances of loss for these characters. However, it is now evident that reconstructing the evolutionary relationships of Pectinoidea will require a more comprehensive taxonomic sampling of the Propeamussiidae sensu lato.

“…Some of these species, such as the Asian moon scallop A. pleuronectes and the saucer scallop A. balloti, are extensively gathered for human consumption. The life histories and biology of these two species are the best known among representatives of the genus due to their commercial harvesting (Morton, 1980;Dredge, 1985aDredge, , 1985bBelda & Del Norte, 1988;Joll, 1989;Cropp, 1993;Joll & Caputi, 1995a, 1995bKangas et al, 2006;Mueller et al, 2012;Tremblay et al, 2015).…”

“…As in other scallops, larvae of A. pleuronectes and A. balloti secrete a byssus, which is lost during ontogeny (Hayami, 1991;Rose et al, 1998;Wang et al, 2001;Kangas et al, 2006), thus remaining as free-living organisms with highly active swimming ability (Yonge, 1936;Gould, 1971;Hayami, 1991;Morton, 1980;Joll, 1989;Tremblay et al, 2015). In this respect, A. balloti is the best swimmer among scallops, reaching longest distances (up to 30 m in two swims), and fastest velocities (up to 160 cm s -1 ) (Joll, 1989).…”

Densely packed monospecific-paucispecific Amusium cristatum-dominated shell beds are signifi cant features in the lower Pliocene deposits of the Almería-Níjar Basin (SE Spain), embedded in distal prodelta fi ne-grained sand and silt. The shells in these concentrations are exceptionally well preserved: articulation is relatively high, fragmentation is low, abrasion is almost lacking, and many shells preserve the original colour pattern. These taphonomic signatures suggest in situ deposition forming autochthonous fossil assemblages, i.e. biological concentrations. Benthic foraminiferal assemblages found in the prodelta deposits indicate that they formed in mesotrophic mid-shelf settings. The A. cristatum accumulations show similarities with recent concentrations of A. balloti from the Shark Bay (NW Australia). The latter species form dense populations in restricted positions of the bay from 10 to 75 m depth. The lowermost depth range of A. balloti is similar to the palaeobathymetry inferred for the A. cristatum beds. Furthermore, the shell beds studied occur in the centre of a relatively enclosed palaeobay. Apart from these coincidences, the proximate ecological causes accounting for the recent concentrations of A. balloti are still obscure. Thus, no straightforward actualistic comparison explains the biological origin of the A. cristatum shell beds. Based on benthic foraminiferal assemblages in the prodelta deposits, A. cristatum concentrations are most likely related to intermittent nutrient and food-particle supply from several deltas feeding RESUMEN En los depósitos del Plioceno inferior de la Cuenca de Almería-Níjar (SE de España) se encuentran niveles de densas acumulaciones monoespecífi cas-pauciespecífi cas dominadas por Amusium cristatum. Dichos niveles están intercalados en arenas muy fi nas y limos depositados en zonas distales de prodelta. Los bivalvos muestran una excelente preservación: articulación relativamente alta, baja fragmentación, abrasion prácticamente nula, y algunos de los pectínidos preservan los patrones de coloración original. Estas propiedades tafonómicas indican una preservación in situ generando asociaciones autóctonas o concentraciones biológicas. Las asociaciones de foraminíferos bentónicos encontradas en los limos de prodelta indican que los niveles de pectínidos se formaron en un ambiente mesotrófi co de plataforma media. Las acumulaciones de A. cristatum muestran similitudes con las concentraciones actuales de A. balloti de Shark Bay (NO de Australia). Esta especie forma densas poblaciones en zonas protegidas de la bahía entre 10 y 75 m de profundidad. El límite batimétrico inferior de A. balloti es similar a la profundidad estimada para las concentraciones de A. cristatum. Asimismo, los niveles estudiados se encuentran en el centro de una paleobahía semicerrada. A parte de estas coincidencias, las causas ecológicas últimas que explican las concentraciones actuales de A. balloti no son del todo conocidas. Por tanto, no se pueden usar aproximaciones actualistas para interpretar lo...
