Talking about the ability of some cetaceans to make sounds and process the echoes bouncing back:

Echolocating cetaceans can see air in our lungs and therefore understand we cannot breathe underwater

Being echolocated by a cetacean is a guarantee the animal will not bump into you by mistake

Echolocation is the use of sound (and relative echoes) to locate objects, estimate their distance, shape and density

7.

Cetaceans can keep their body warm in the water by means of:

A thick layer of proteins under their skin, called blubber

A huge production of heat, due to constant swimming

A thick layer of fat under their skin, called blubber

A special countercurrent blood-vessel system, which limits the quantity of heat lost from their flukes and flippers

8.

Why is a stranded cetacean in a highly life-threatening condition?

Because it cannot breathe

Because its body design was not conceived by Nature to fully cope with gravity out of the water
