根据在新西兰水域捕获的巨型乌贼的肠道内容物中发现的大量可识别的猎物，提出了巨型乌贼（大王乌贼）的新饮食信息。猎物属于两种鱿鱼：Nototodarus sp.和Architeuthis dux。在胃内容物中出现nottodarus并不新鲜，但Architeuthis的出现仍然是新的。大量的触手棒的碎片，包括腕骨、手骨、指骨吸盘和指骨袋，说明了同类相食的可能性——这是迄今为止在这一属中未被报道过的行为。本文简要介绍了大Architeuthis的饮食，并对同类相食（如自噬）的替代方法进行了评估。
New diet information for the giant squid (Architeuthis dux) is presented based on the identification of substantial identifiable prey items recovered from the gut contents of a specimen caught in New Zealand waters. Prey items are attributed to two species of squid: Nototodarus sp. and Architeuthis dux. The incidence of Nototodarus in the stomach contents is not new, but the occurrence of Architeuthis remains is. Numerous fragments of an Architeuthis tentacular club, consisting of carpus, manus, and dactylus suckers, and the dactylic pouch, introduce the possibility of cannibalism-a hitherto unreported behaviour in this genus. A synopsis of Architeuthis diet is presented and alternatives to cannibalism (such as autophagy) are evaluated.
