The argonaut octopus, of the family Argonautidae, belongs to a group of pale pink-spotted octopuses. Unlike the heroes that sailed the Argo in the Greek myth, these octopuses are known for traversing the open ocean by way of a delicate, curved, creamy white vessel—an external casing, often referred to as a “shell,” that gave them their common nickname, the “paper nautilus.” These creatures baffled naturalists and philosophers for two millennia, even fooling Aristotle, who believed that they used their large pair of webbed dorsal arms as “a sail” to catch the briny breeze and floated across the ocean’s surface like paper boats. These myths carried weight for centuries, even among naturalists in the 19th century.It wasn’t until the early 1830s when self-taught French naturalist, Jeanne Villepreux-Power began researching the Argonauta argo, or the greater argonaut, that we learned the true origins of their “shells.” Along the way, Villepreux-Power tried new methods for studying sea creatures that gave insights not just into the paper nautilus, but also helped us to better understand other creatures of the sea today.
