Feeding rates of Cetacea
A variety of porpoises and dolphins of the superfamily Delphinoidea, ranging through three magnitudes of weight from the harbour porpoise Phoconea to the killer whale Orcinus, have now been kept in captivity. From aquarium records of body weights and weights of food ingested, daily food consumption...
