Early beak development in Argonauta Nodosa and Octopus Vulgaris
CEPHALOPOD BIOLOGY AND EVOLUTION RM Franco-Santos, J. Iglesias (pdf)

Keywords Argonauta Á Beak Á Cephalopod Á Octopus Á Paralarvae Á
Rostrum Introduction Incirrate octopods employ distinct life strategies.

Interesting study of para larvae jaw sizes and descriptions comparing both species. Of note, new hatched paper nautilus and vulgaris have teeth. The paper suggests these jagged edges of the beaks are used more for securing the prey than any kind of chewing activity.
