Global barcoding of the deep-sea snail genus Phymorhynchus reveals surprising distribution ranges and genetic diversity.

Abstract excerpt

For rare fauna inhabiting insular habitats, specimens from geographically distant locations are often assumed to be distinct species without a detailed assessment of their genetic diversity. The raphitomid snail genus Phymorhynchus includes a species complex considered endemic to deep-sea hot vents and cold seeps. Despite small morphological differences, existing species hypotheses largely relied on geographic...
