On the edge of a deep biosphere: Real animals in extreme environments

J. J. Childress, C. F. Fisher, H. Felbeck, and P. Girguis

This paper considers the possibility of animals living in a subsurface environment on the global mid-ocean ridge system. It considers the possible environments and looks at the possibilities of animal inhabitants of the subsurface biosphere based on adaptations of animals to other extreme habitats. We conclude that there are known bridging inhabitants of the subsurface biosphere, that part-time inhabitants are extremely likely, and that there could be full-time inhabitants if conditions are stable within the tolerance limits of metazoans for time periods of months.
