An integrative taxonomic approach revealsOctopus insularisas the dominant species in the Veracruz Reef System (southwestern Gulf of Mexico)

Abstract: The common octopus of the Veracruz Reef System (VRS, southwestern Gulf of Mexico) has historically been considered as Octopus vulgaris, and yet, to date, no study including both morphological and genetic data has tested that assumption. To assess this matter, 52 octopuses were sampled in different reefs within the VRS to determine the taxonomic identity of this commercially valuable species using an integrative taxonomic approach through both morphological and genetic analyses. Morphological and genetic data c… Show more

“…We analysed genome-wide RAD loci to investigate the phylogenetic and specieslevel relationships within the highest value fisheries target species of octopus in the world. Our study provides evidence for the existence of three cryptic species within the 37 , which also appears to be true for O. insularis from the Caribbean and eastern North Brazil 38,39 . Both of the above examples suggest these taxa can maintain gene-flow despite connectivity requiring trans-tropical dispersal.…”

“…from Old Providence. An O. insularis sequence from (González-Gómez et al, 2018) was included in the analysis, but during trimming it was erased due to its low coverage in the alignment. Therefore, together with the lack of rhodopsin sequences for Caribbean O. vulgaris, the mitochondrial results regarding O. tayrona could not be confirmed with the nuclear marker.…”

“…It is also worth noting that some nominal species listed in the database are known to comprise species complexes. In contrast to the Octopus vulgaris complex (a focus of much recent research, e.g., Leite et al, 2008;Amor et al, 2014Amor et al, , 2015Amor et al, , 2017Gleadall, 2016;González-Gómez et al, 2018), the complexes of Sepia pharaonis (Anderson et al, 2011), Sepioteuthis lessoniana (Cheng et al, 2014) and Lolliguncula brevis (Sales et al, 2014) are not welldefined in geographical terms and therefore are listed as single species. Therefore, the species richness patterns presented here are conservative estimates.…”
