Cetaceans, compared to humans, have:

A higher concentration of myoglobin in muscles

A bigger lung volume relative to total body volume

A higher amount of blood in their circulatory system, relative to total body weight

More efficient biochemical pathways, which enhance their tolerance towards lactic acid

5.

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

Because it cannot efficiently dissipate heat on land (overheating)

Because it quickly gets dehydrated and its skin is also sensitive to the ultraviolet radiations of the sun

8.

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

9.

Copepods

Krill

Small fish

Marine mammals
