Alfred Brehm (1829–1884) was one of the most significant naturalists of the 19th century.Estimates of the number of recorded fatalities caused by blue-ringed octopuses vary, ranging from seven to sixteen deaths most scholars agree that there have been at least eleven.

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 1,500 lb). 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 beak had a lower rostral length of 42.5 millimeters ( 1 + 11⁄ 16 in). One of the largest beaks ever recorded was on a 495-kilogram (1,091 lb) colossal squid. Colossal squid use their beaks for shearing and slicing their prey's flesh to allow the pieces to travel the narrow esophagus.
