Research shows how insects use trapped oxygen to breathe underwater Hundreds of insect species spend much of their time underwater, where food may be more plentiful. MIT mathematicians have now figured out exactly how those insects breathe underwater. By virtue of their rough, water-repellent coat, when submerged these insects trap a thin layer of air on their bodies. These bubbles not only serve as a finite oxygen store, but also allow the insects to absorb oxygen from the surrounding...
How the Earth adapted to life has much to do with the generation of a stable oxygen atmosphere. But how life adapted to Earth often hinges on whether oxygen is a poison. New research on insect oxygen use highlights the novel ways that life has shaped the Earth, and vice versa. Astrobiology Magazine -- A new study investigating the respiratory system of insects may have solved a mystery that has intrigued physiologists for decades: why insects routinely stop breathing for minutes at a time....
