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.
They are some of the largest flying birds in the world. The great albatrosses have wingspans which can reach 3.7 m (12 feet).
