Argonautidae is a family of cephalopods encompassing the modern paper nautiluses of the genus Argonauta along with several extinct genera of shelled octopods. Molluscs are animals belonging to the phylum Mollusca. There are around 250000 extant Species within the phylum with an estimated 70000 The cephalopods ( Greek plural (kephalópoda "head-feet" are the Mollusc class Cephalopoda characterized by The Argonautoida is a superfamily of the suborder Incirrina.

All eggcases possessing nodes, ribs, and a double keel, with the exception of those of Kapal batavus, have been assigned to Argonauta. Kapal is a monotypic genus of shelled octopods comprising the species Kapal batavus. The argonauts ( Genus Argonauta, the only extant genus in the Argonautidae family are a group of Pelagic Octopuses Eggcases lacking these morphological features have been placed in the other Argonautidae genera. ^[1]

Fossil Argonautidae eggcases have been described from Japan, New Zealand, Sumatra, Europe, and California. For a topic outline on this subject see List of basic Japan topics. New Zealand is an Island country in the south-western Pacific Ocean comprising two main landmasses (the North Island and the South Island Sumatra (also spelled Sumatera) is the sixth largest island in the world (approximately 470000 km² and is the largest island entirely in Indonesia (two California ( is a US state on the West Coast of the United States, along the Pacific Ocean. ^[1]
