A thin membrane is connected to the anterior border of the head and mantle, located along the borders of the dorsal and ventral chambers. This thin membrane prevents water from exiting the dorsal chamber. Water can exit the ventral chamber via a small funnel.

These squids have a horizontal partition over the mantle cavity. The mantle cavity is divided into 2 dorsal chambers and 1 ventral chamber. An opening in the posterior end of the horizontal membrane connects the dorsal chamber to the ventral chamber. An inhalant opening on the head connects the
