ventiloiduns
Ventiloiduns are a hypothetical group of organisms proposed within speculative biology. The concept suggests that life could evolve in environments with extremely low oxygen levels, or even in the absence of oxygen altogether. Instead of relying on cellular respiration that utilizes oxygen as a final electron acceptor, ventiloiduns would employ alternative metabolic pathways. These pathways might involve the use of other molecules, such as sulfur compounds or certain metals, to extract energy from their surroundings.
The term "ventiloidun" itself is derived from "ventilation" and the Greek suffix "-oid," implying a form or
Their biological processes would be fundamentally different from those found in Earth's surface biosphere. This could
