Abstract
The family Conidae, commonly known as cone snails, is one of the most intriguing gastropod groups ow-ing to their diverse array of feeding behaviors (diets) and toxin peptides (conotoxins). Conus lischkeanus Weinkauff, 1875 is a worm-hunting species widely distributed from Africa to the Northwest Pacific. In this study, we report the mitochondrial genome sequence of C. lischkeanus and inferred its phylogenetic relationship with other Conus species. Its mitochondrial genome is a circular DNA molecule (16,120 bp in size) composed of 37 genes: 13 protein-coding genes (PCGs), 22 transfer RNA genes, and two riboso-mal RNA genes. Phylogenetic analyses of concatenated nucleotide sequences of 13 PCGs and two riboso-mal RNA genes showed that C. lischkeanus belongs to the subgenus Lividoconus group, which is grouped with species of the subgenus Virgiconus, and a member of the largest assemblage of worm-hunting (ver-mivorous) species at the most basal position in this group. Mitochondrial genome phylogeny supports the previous hypothesis that the ancestral diet of cone snails was worm-hunting, and that other dietary types (molluscivous or piscivorous) have secondarily evolved multiple times from different origins. This new, complete mitochondrial genome information provides valuable insights into the mitochondrial genome diversity and molecular phylogeny of Conus species. © Yucheol Lee & Joong-Ki Park.
