Match the adaptation type to the adaptation.

Draggable itemCorresponding Item
Water Conservation
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.
Sensory adaptation
Drag is reduced by hydrodynamic body forms.
Swimming adaptations
Most marine mammals rarely drink fresh water; instead, they: Utilize water present in their food, inspired air, and blubber.
Thermoregulation
Marine mammals communicate underwater with sound, and many species use sound (echolocation) to locate prey.
