Mitochondria-packed muscles power duck dives

Mitochondira-packed muscles power duck divesCatching food is hard enough, but animals that dive underwater in search of a meal face a more difficult challenge: how to get enough oxygen to their muscles to keep searching for food while being unable to breathe.Lots of deep diving animals have evolved ways around this issue.However, diving ducks needed to come up with a different way so that they could remain light enough to fly off after eating their fill.So, ducks power their dives using their energy-expensive leg muscles.But what allows ducks to dive under the water and forage for food, but be unconcerned about the fact that they can't get the oxygen they need from the air to make more energy?To solve this conundrum,
