As illustrated in fig 6, the energetic cost of swimming for marine mammals is greater than predicted for salmonid fish of similar body size despite specialization of the body and propulsive surfaces for aquatic locomotion, the cost of transport for swimming by seals and sea lions is 23–40 times higher than predicted for swimming fish. Cost-efþcient diving by marine mammals this energy-conserving strategy allows marine mammals to increase aerobic dive duration and achieve remarkable depths despite limited oxygen that marine mammals swim constantly at cost-efficient routine speeds during diving (3, 4.

Sink or swim or glide photo: john calambokidisa blue whale diving off the coast of northern california whales, dolphins, and seals seem to defy reality with every deep dive into the big blue.
Locomotor activity by diving marine mammals is accomplished while breath-holding and often exceeds predicted aerobic capacities video sequences of freely diving seals and whales wearing submersible cameras reveal a behavioral strategy that improves energetic efficiency in these animals. Sink or swim: strategies for cost-efficient diving by marine mammals science 288:133-136 locomotor activity by diving marine mammals is accomplished while breath-holding and often exceeds predicted aerobic capacities.
Locomotor activity of four species of diving marine mammal representative deep dives are presented for the ( a ) weddell seal (maximum depth = 385 m), ( b ) northern elephant seal (333 m), ( c ) bottlenose dolphin (115 m), and ( d ) blue whale (84 m) sink or swim: strategies for cost-efficient diving by marine mammals terrie m williams. Transitions in locomotor mode during diving were attributed to buoyancy changes with compression of the lungs at depth, and were associated with a 9–60 % reduction in the energetic cost of dives for the species examined.
