The air we breathe is made up of 78% nitrogen - an inert, completely harmless gas - at the surface at least, but as we dive into the ocean depths it's another matter....When diving, we experience pressure that is twice as great as the pressure on... 
Marian Locksley's curator insight,
May 23, 7:38 AM
All vertebrates have a reflex response to diving (the ‘diving response'), that allows them to limit nitrogen uptake into the blood and body tissues and conserves oxygen, allowing them to dive for longer. The diving response has two main effects on the body: 1) reduced blood flow to muscles (peripheral vasoconstriction), and 2) reduced heart rate (bradycardia). Both of these limit gas transport around the body, conserving oxygen for the vital organs, and limiting nitrogen uptake by the blood and body tissues. Many marine mammals have the added ability to store gas in their windpipe (trachea) when diving. The trachea, together with smaller branches in the lungs, are reinforced by rings of cartilage, and when the air sacs within the lungs (alveoli) collapse under pressure, gas is forced out into these strengthened lung cavities, rather than the bloodstream. This prevents excess nitrogen entering the blood as they descend. Delete the scoop?

A whale pod off the coast of South Africa was seen feeding one of their disabled members.
Marian Locksley's curator insight,
May 21, 3:14 AM
In many animal societies, if a member of a group is gravely wounded or born with disabling deformities, that animal becomes an unsustainable burden on the others, and is often left behind at the mercy of predators, hunger and disease. Not so with killer whales. They are among the few species in the world to look after members of their family who cannot look after themselves. Their patience and compassion for each other surpasses, perhaps, even that of humans The most recent example of this extraordinary commitment to one another was revealed today in the U.K.'s Daily Mail, which ran a story and photo essay of a disabled young male orca off the coast of South Africa; he's missing a pectoral fin and the normally towering dorsal fin that sprouts from the backs of mature bulls. These disfigurements make it impossible for the whale to hunt alongside his pod. Luckily for him, they are only too willing to hunt for their disabled pod mate. Delete the scoop?
