Sharks can hold their breath, and Saturn has set a new record for the number of satellites — here's a look at last week's science news. Sharks can hold their breath Scalloped hammerhead sharks have evolved a unique method to avoid losing body heat when they hunt in deep cold waters: they close their gills. The sharks keep their core temperature stable by not opening their gills or mouth during the dive for prey, effectively ‘holding their breath’. So far, scalloped hammerheads are the first fish found to do this, but other sharks and fish might have the same adaptation.
