Oxygen is necessary to sustain most terrestrial life. Oxygen is used in cellular respiration and many major classes of organic molecules in living organisms contain oxygen, such as proteins, nucleic acids, carbohydrates, and fats, as do the major constituent inorganic compounds of animal shells, teeth, and bone.
From wingtip to wingtip, P. sandersi measured at least 6.4 meters. The wandering albatross, the worldâs largest living bird, has a wingspan of 3.5 meters, and the giant, extinct South American condor, Argentavis magnificens, was right around 6 meters.
The albatross has the largest wingspan of any other bird species, at approximately 11.5 feet (3.5 m). This large wingspan allows the bird to glide for hundreds of miles without ever flapping its wings. By the time an average albatross reaches 50 years old, the bird has flown over 3.7 million miles (6 million km).
