In a study published today in Genome Biology and Evolution, a team of biologists sequenced genomes from the species Argonauta argo, the greater argonaut, to figure out the origin of argonaut shells.

Of these, Argonauta argo, or the greater argonaut, is the largest and lives in oceans all around the world. The three other species have more restricted ranges. Argonauta nouryi makes the smallest egg ...

They did a genetic analysis of Paper Nautilus or greater argonaut (Argonauta argo) and found a unique origin for its protective casing. Only female argonauts carry shells.
