Conditioning techniques were developed demonstrating that pure tone frequencies under water can exert nearly perfect control over the underwater click vocalizations of the California sea lion (Zalophus californianus). Conditioned vocalizations proved

THE incessant, raucous barking in air by the California sea lion (Zalophus californianus) is well known. Wenz1 presented sonograms of barks from Zalophus which were recorded during the breeding season by an underwater hydrophone at a depth of 360 fee

Study was made of the vocal repertoires of three species of seals and sea lions which, until now, have been reported as not being very vocal under water. Sonograms of underwater vocalizations are presented for the gray seal and the harbor seal for th

Gentry and Peterson1 have compared data obtained from a sea otter (Enhydra lutris) on an underwater size discrimination task with data obtained by Schusterman et al.2 using two sea lions (Zalophus californianus). Although Gentry and Peterson did not

Aerial visual acuity and underwater visual acuity were measured in two sea lions (Zalophus californianus) by training them to emit click bursts if they saw a striped target or to remain silent if they saw a gray target. The closest grating spacings t

SOME investigators have suggested that seals and sea lions rely primarily on sight when catching food under water1–4. Earlier experiments on the visual acuity of pinnipeds under water2 were largely unsuccessful in keeping animals at a minimum dista
