In researching the anatomy of the giant squid, I have found a discrepancy re- the number of hectocotyli in this species. According to Roper and Boss ("The Giant Squid", Sci. Amer. 264(4):96-105) the kraken has 2 hectocotylized arms. O'Shea's "Architeuthis Reproduction" article states that males have no hectocotyli. Can someone clarify this for me? Thank you.
