Respiration and the Effects of Pressure, marine and terrestrial mammals scale isometrically with body mass. Compared with terrestrial mammals, marine mammals have a larger tidal volume (relative to total lung volume), exhibit high tidal flows (especially in small Odontoceti), and breathe apneustically in which there are periods of apnea.

Locomotion,ared to air. There are two types of drag: pressure drag and friction drag. Pressure drag is greatly reduced by a streamlined or fusiform body shape. Total drag increases with body mass for marine mammals primarily due to friction drag. Active drag of a free-swimming animal is generally assumed to be

Physiological Adaptations for Breath-Hold Diving,ile underwater. The pulmonary and cardiovascular changes associated with the dive response include cessation of breathing (apnea), a decrease in heart rate (bradycardia), a concurrent reduction in cardiac output, and peripheral vasoconstriction that maintains central arterial blood pressure. A dive

Feeding and Digestion,aleen to filter large numbers (e.g., swarms of krill or schools of fish) of smaller prey, while Odontoceti generally use raptorial biting and/or suction to capture larger, individual prey, often after pursuit. Some species of Phocidae and walruses rely primarily on suction feeding while most use rap
