“…Different shell colors resulting from phenotypic plasticity due to environmental factors are indistinguishable by genetic information. It was found that three genetic species of Mactra chinensis could not be determined reliably based on analysis of the shell coloration due to the plasticity of these morphological characters (Reunov et al, 2021); in Corbicula population, morphotypes defined by internal shell color were indistinguishable in genetic background (Li et al, 2022), and there are also examples of different species with the same shell color (Williams et al, 2016), different species of marine snails Clanculus pharaonius and Clanculus margaritarius were examined that contained different pigments but produced similar colors. This fact shows that there may be some adaptive value for these colors and patterns despite differences in their habitats.…”

The giant triton snail (Charonia tritonis) is widely distributed in tropical coral reefs in the Indo-West Pacific. Its distribution areas in China include the Penghu Islands, Hengchun Peninsula, and Xisha Islands. In this study, we use Multivariate Analysis of Variance (MANOVA) to compare the live weight and shell length between different shell colors of C. tritonis. In addition, we conducted sequence analysis of the mitochondrial cytochrome oxidase (COI) gene to assess the affinity of C. tritonis with two different shell colors based on the sample we obtained. Then, we constructed phylogenetic trees using the maximum likelihood (ML) and Bayesian Inference methods, and constructed haplotype network diagrams. In addition, we performed Tajima’s D and Fu’s neutrality tests. The results show that The Partial mitochondrial COI sequences of 28 C. tritonis were all 603 base pairs in length, and seven haplotypes were detected from the samples, besides, the gene flow was calculated to be 11.78, the genetic differentiation coefficient was 0.02078. Our results indicated that the population size of C. tritonis remained relatively stable. Besides, the genetic and size differentiation between the two different shell colors was small, and individuals of C. tritonis with different shell colors belong to the same genetic clade. In fact, the two morphotypes could not be distinguished by both genetic and morphometric data. The mitochondrial COI gene fragments of the two different shell colors were sequenced and analyzed to accumulate information about the population genetics of C. tritonis and to provide a scientific basis for the conservation of its species resources.The giant triton snail (Charonia tritonis) is widely distributed in tropical coral reefs in the Indo-West Pacific.

“…Correlations between habitat divergence and morphological and genetic patterns are well established in fish, which have been helpful to understand potential drivers of fish diversity patterns and to design management measures. However, the influence of lotic and lentic habitats on morphotypes and genetic divergence has not been well established for Corbicula fluminea , one of the most invasive bivalves globally, which is a drawback in understanding how habitat‐related population and genetic patterns can be used for formulating prevention and control management of this invasive species (Ilarri et al., 2019 ; Karatayev et al., 2005 ; Li et al., 2022 ; Zeng et al., 2023 ). Corbicula fluminea has successfully invaded aquatic systems in America and Europe that contain both lotic and lentic local habitat conditions (Bespalaya et al., 2018 ; Crespo et al., 2017 ; Haponski & Foighil, 2019 ), with a total of seven morphotypes being reported from different invasion locations (Appendix S1 ), specifically four morphotypes (Forms A–D) in America and three (Forms R, Rlc, and S) in Europe (Haponski & Foighil, 2019 ; Marescaux et al., 2010 ).…”

“…Additionally, C. fluminea is an important fishery resource in East Asia, which is one of its native distribution areas (Bi et al., 2014 ; Li et al., 2022 ). Diverse morphological and genetic groups have also been found from these native populations (Wang et al., 2014 ; Wu et al., 2019 ).…”

“…For example, the bivalve is an important composition of fisheries in the Hongze Lake, China, where the annual harvest is approximately 2 × 10 4 t, supporting an artisanal fishery around the lake (Hongze Lake Fisheries Administration Committee Office of Jiangsu Province, unpublished data). Our previous study identified two morphotypes (Morphs C and D, Appendix S1 ) with significant genetic differentiation based on the shell sculpture of C. fluminea in the lake (Li et al., 2022 ). Furthermore, results suggested that Morph C may have higher density in low‐flow environments, whereas Morph D may be competitive in high‐flow environments (Li et al., 2022 ).…”

Differences in local habitat conditions are often implicated as drivers for morphological and genetic divergence in natural populations. However, there are still relatively few studies regarding how divergent habitats influence patterns for morphotypes and genetic lineages in aquatic invertebrates. In this study, we explored the morphological patterns, genetic divergence, and distributions of a bivalve, Corbicula fluminea, in a lotic–lentic system. Sampling locations included lotic, ecotone, and lentic habitats. First, we found two lineages (Lineages A and B) with significant genetic divergence that primarily corresponded to two morphotypes (Morphs D and C) of C. fluminea. Lineage A consisted of 88.68% Morph D (shell sculpture: 8–14 ridges/cmsh) and 11.32% Morph C (shell sculpture: 15 ridges/cmsh) individuals and had genetic similarity to invasive populations. Lineage B consisted of only Morph C (shell sculpture: 15–23 ridges/cmsh). Second, we revealed clear effects of habitat on the spatial distribution patterns for the two lineages of C. fluminea. Lineage A was dominant in lotic habitats, with a significantly higher density than that of Lineage B in these locations. Lineage B was dominant in lentic habitats. However, both lineages had their highest densities in the ecotone habitat, without clear dominance and no significant difference in density between groups. Individuals of Lineages A and B are different in shell morphology, which may be related to a benefit trade‐off between shell shapes that allow for rapid burrowing and holding position in different flow conditions. The distribution patterns indicate that Lineages A and B may not prefer uniquely lotic and lentic habitats, but each lineage is more tolerant to one habitat type, respectively. Generally, our study established a correlation among morphotypes, lineages, and different habitats for C. fluminea along a lotic–lentic gradient system, which has important implementations for fisheries management units and for understanding the role of habitat preference for this species in monitoring for pioneer dispersal in invasive species management.
