Scientists have discovered a remarkable new form of symbiosis — a bacterium that lives inside a single-celled organism (a ...

Some animals have evolved to survive without oxygen in extreme environments. Creatures like **Hydra** can switch to anaerobic ...

Here are seven amazing animals that do not require oxygen to survive.

Deep-seafloor organisms consume oxygen which scientists believe is produced by seawater electrolysis without light or sunshine.

Most life on Earth depends on oxygen—but not these creatures! From deep-sea organisms to microscopic marvels, these 9 animals have evolved to survive without oxygen in ways that defy science.

Professor Andrew Sweetman and his colleagues set out to measure seafloor respiration but ... However, the "dark oxygen" discovered by Sweetman's team operates without either.

The revelation that oxygen can be generated in complete darkness not only revises theories about the origins of life on Earth but also expands the potential for finding life on planets without ...

Oxygen is hard to produce without the continuous energy that comes from sunlight, but other scientists have also encountered unexpected oxygen molecules in remote, light-deprived places.

"We are already in conversation with experts at Nasa who believe dark oxygen could reshape our understanding of how life might be sustained on other planets without direct sunlight. "We want to go ...

“We know kleptoplasty is happening here, but we needed more research to understand why this foraminiferan is so successful in the dark, without oxygen.” The ability of foraminiferans to thrive in ...
