Antarctoneptunea is a genus of sea snails, marine gastropod mollusks in the whelk family Austrosiphonidae. [1] [2] [3] [4]
Antarctoneptunea marine snails occur in deep water surrounding New Zealand and in Southern Ocean encircling Antarctica, particularly in the Ross Sea. [2] [5] [3] [6]
Molecular phylogenetic trees based on mitochondrial genomic and nuclear ribosomal DNA sequence data indicate that Antarctoneptunea is closely related to the Northern Hemisphere genus Kelletia , and Penion siphon whelks found in waters surrounding New Zealand and Australia. [3] [6] [1] It has been suggested that some Antarctic fossil species of Penion are misclassified Antarctoneptunea. [7]
