Humans have long envied fish their ability to breathe underwater. A few extreme athletes trained in the sport of freediving—in which divers swim underwater or perform aquatic feats on a single breath—have been able to hold their breath for more than 20 minutes. (The current world record is held by Croatian free diver Budimir Šobat, who held his breath while staying underwater for 24 minutes, 11 seconds in February 2018.) But that’s not breathing underwater.
So envious are we, in fact, that it shouldn't surprise us that there have been songs written about this elusive phenomenon.
