Underwater Sounds of Pinnipeds

Abstract

Descriptions and analyses are presented of underwater sounds made by six species of seals in captivity, Zalophus californianus, Phoca vitulina, P. (Pusa) hispida, P. (Pagophilus) groenlandica, Halichoerus grypus, and Cystophora cristata. The suitability of these very faint sounds for echolocation is discussed.
