[Velociraptor-style dinos] had one of the most efficient respiratory systems of all animals, similar to that of modern diving birds like penguins, fossil evidence shows.
It fuelled their bodies with oxygen for the task of sprinting after prey
It seems that in yet another way penguins are indeed a beastie to be feared. They can out-dive, out-swim, out-cold & now out-breathe yet another set of competitors...
So it seems reasonable to propose... that if you want some genes to blend with yours in search of the perfect being (give or take a bilennia or few), you could probably do a lot worse than borrowing from Aptenodytes/Eudyptula. (-:
