Distribution

Antarctoneptunea marine snails occur in deep water surrounding New Zealand and in Southern Ocean encircling Antarctica, particularly in the Ross Sea.[1][4][2][5]

Evolution

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.[2][5] It has been suggested that some Antarctic fossil species of Penion are misclassified Antarctoneptunea.[6]
