Cephalopod remains from the stomachs of Sperm whales caught off Peru and Chile
One thousand cephalopod lower beaks from random samples of the stomach contents of four Sperm whales caught off Peru and Chile are identified and/or described. Non‐random samples of stomach contents from 10 whales were also examined. The size of the lower beaks is used to estimate the mean and the t...
