Many beaks have also been discovered in the stomachs of sperm whales, as the stomach juices dissolve the soft flesh of the squid, leaving the hard beaks behind. The largest beak ever discovered in this way had a lower rostral length of 49 millimeters ( 1 + 15 ⁄ 16 in), indicating that the original squid was 600 to 700 kilograms (1,300 to ...
