Whether the eggs are laid into a large gelatinous matrix, as in most of the large oceanic squids or are released individually, is unknown, although the large nidamental glands suggest the former method.

The sperm whale is the primary predator of giant squids. Male squids appear to be smaller than females. The tentacular clubs are narrow and have suckers, which are sub-spherical cups lined with sharp, finely serrated rings of chitin, in four longitudinal rows.
