Allonautilus scrobiculatus is a species of nautilus that Ward and a colleague had previously discovered off of Ndrova Island in Papua New Guinea. Nautiluses are small, distant cousins of squid and cuttlefish. They are an ancient lineage of animal, often christened a “living fossil” because their distinctive shells appear in the fossil record over an impressive 500-million-year period. The recent sighting indicates there is still much to learn about these creatures.
