franciscana, stomach contents, digestion rate, captive animal


The data consists of spreadsheets containing (i) otolith and cephalopod beak numbers and sizes, and the time of recovery for seven different prey species of different meals; (ii) conditions of prey structures for each meal and its time of recovery; and (iii) the times that the plastic colour markers were ingested and evacuated from a feeding experiment with a franciscana dolphin in captivity.
