Match the adaptation type to the adaptation.

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