Sensory adaptation | arrow_right_alt | Have a high tolerance to lactic acid and carbon dioxide. Their muscles can work anaerobically (without oxygen) while they hold their breath. |
Swimming adaptations | arrow_right_alt | A large body with a small surface-to-volume ratio reduces heat loss. Blubber or thick underfur is used as insulation. |
Deep diving | arrow_right_alt | Drag is reduced by hydrodynamic body forms. |
Thermoregulation | arrow_right_alt | Most marine mammals rarely drink fresh water; instead, they: Utilize water present in their food, inspired air, and blubber. |
Water Conservation | arrow_right_alt | Marine mammals communicate underwater with sound, and many species use sound (echolocation) to locate prey. |
