Cephalopod size criticised by giant squid experts (Greshko, 2016). O'Shea (2003a) put the maximum weight of female giant squid at , based on the examination of some 105 specimens as well as beaks recovered from sperm whales (which do not exceed the size of those found in the largest complete specimens). Giant squid are sexually size dimorphic, with the maximum weight for males estimated at (O'Shea, 2003a), though heavier specimens have occasionally been reported (see Deagle "et al.", 2005 for specimen and Hofilena, 2014 for specimen).
