Colossal squid
The largest recorded specimen was captured in 2007 by a New Zealand fishing boat off Antarctica. It was initially estimated to measure in length and weigh . The squid was taken back to New Zealand for scientific study. A study on the specimen later showed its actual weight was , but it only measured in total length as a result of the tentacles' shrinking "post mortem".
Cephalopod size
A subadult female found in the Ross Sea in March 2003 also had a mantle length of around , and measured in total length, but was comparatively light at only (Griggs, 2003; McClain "et al.", 2015). Another giant specimen, a female measuring in total length and weighing , was recovered intact in 2014 (Farquhar, 2014). Other notably large colossal squid specimens include an immature female taken by trawl off Dronning Maud Land in 1981 ( ML and TL; Ellis, 1998a:147), a specimen caught alive in South Georgian waters in 2005 (estimated TL and weight; [Anonymous], 2005b), and two specimens recovered from sperm whale stomachs between 1956 and 1957 off the South Shetland Islands and South Orkney Islands (reportedly around TL, respectively; Sweeney & Roper, 2001:56; see Korabelnikov, 1959:103 and Yukhov, 1974:62).
