Description
Summary:The pteropod community structure in the oceanic waters of the southern Gulf of Mexico (sGoM) was analyzed in June 2015. For the first time, we used an integrative morphological and molecular approach for pteropod identification in the sGoM. A total of 32 pteropod taxa were morphologically identified from the oceanic waters of which 12 were successfully sequenced, at least for one of the loci implemented (COI and 28S). The molecular data support the taxonomic identity of half of them. However, despite the morphological differences in the other six taxa, the molecular evidence displayed low genetic variability, resulting in a resolution to the genus level. During the sampling campaign, the oceanographic conditions were very homogeneous in all the sampled areas, with high surface temperatures (SST >27.5 °C) and low chlorophyll (CHL
