Males are dwarfs with a mantle length of about 30 mm. Characteristics Arms Lateral arms much shorter than dorsal and ventral arms. Water pores Present at base of ventral arms in both sexes. Mantle Reticulate pattern of ridges on ventral surface of mantle in females. Funnel Locking-apparatus formed by permanent, turgid and strongly recurved corners of funnel.

Swimbladder Present in females. The eggs develop in the long, winding oviducts until hatching.

The hatchling is easily recognized by the retarded development of the lateral arms which is characteristic of all stages.
