The shells of strombids varied greatly, from small and fusiform to large and decorated with a strongly stretched outer lip ( Latiolais et al., 2006). The Indo-Pacific strombid Conomurex luhuanus is also an exploited species in coastal countries ( Ulm et al., 2019). gigas has been listed as a vulnerable commercial species in the CITES Appendix II since 1992. For example, the west Atlantic strombid Aliger gigas is considered one of the most important fishery resources in the Caribbean ( Machkour-M’Rabet et al., 2021). ![]() ![]() They are widely distributed in tropical and subtropical seas all over the world, and some species possess high ecological and economic values. Our results indicate that complete mt genomes would be a promising tool to reconstruct a robust phylogeny of Strombidae with an increased taxon sampling in the future.Īs the largest group within Stromboidea, the family Strombidae comprises about 120 extant species ( MolluscaBase, 2022a). A correlation between strombids speciation events and paleoclimate change was presumed. labiatum were confirmed within Strombidae, and several morphological similarities were observed corresponding to the present phylogeny. Within Stromboidea, the sister group formed by Clade I and Clade II were fully recovered and supported by morphological synapomorphies as previously suggested. Two different datasets derived from mitochondrial genes were constructed to resolve the internal phylogenetic relationships of Stromboidea and Strombidae. The three newly sequenced mt genomes contained 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, two ribosomal RNA (rRNA) genes, and several non-coding regions, indicating a similar pattern with respect to genome size, gene order, and nucleotide composition compared with those of other strombids reported before. In the present study, the complete mitochondrial genomes of Lentigo lentiginosus, Euprotomus aratrum, and Canarium labiatum were sequenced. In order to better understand how morphological characteristics evolved within Strombidae, a robust phylogenetic framework is needed. The marine gastropod Strombidae is widely distributed in tropical and subtropical regions all over the world and possesses high morphological diversity. 2College of Marine Science, Hainan University, Haikou, China.1State Key Laboratory of Marine Resource Utilization in South China Sea, Hainan University, Haikou, China.Fengping Li 1,2, Jiawen Zheng 1,2, Qingxia Ma 1,2, Zhifeng Gu 1,2, Aimin Wang 1,2, Yi Yang 1,2* and Chunsheng Liu 1,2* ![]()
