Relating to or describing life or organisms that can survive and function without oxygen.
From Greek 'an-' (without) + 'oxys' (sharp, oxygen) + 'bioticos' (of life). A scientific term coined in the 20th century to describe anaerobic organisms.
Anoxybiotic organisms are absolutely wild—some bacteria deep underground have been living without oxygen for millions of years, breaking down rocks and surviving in conditions we thought impossible for life!
