10.

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

Echolocating cetaceans can recognise a woman being pregnant and may be therefore particularly careful and cautious in her presence

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
