👉 Anaerobiales are bacteria that do not require oxygen for growth, living in anaerobic environments such as soil and seawater. They include some species of archaea like Methanococcus and Eubacterium, which are also known as "bacteria" but are actually single-celled organisms with no cell walls or organelles. Anaerobiales are found in a wide range of habitats including the ocean floor, deserts, and even underground caves.
