Antarctoneptunea is a genus of sea snails, marine gastropod mollusks in the whelk family Austrosiphonidae.[1][2][3][4]
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.[3][6][1] It has been suggested that some Antarctic fossil species of Penion are misclassified Antarctoneptunea.[7]
