Another case is animals like the snow leopard living on steep rock faces such as are found in mountains. Some light animals are able to climb up smooth sheer surfaces or
Underwater habitat depth of approximately 12 m. A concept design by internationally recognized conceptual designer and futurist Phil Pauley. The Sub-Biosphere 2 is the original self sustainable underwater habitat designed for aquanauts, tourism and oceanographic life sciences and longterm human, plant and animal habitation. SBS2 is a seed bank with eight Living Biomes to allow human, plant and fresh water interaction, powered and controlled by the Central Support Biome which monitors the life systems from within its own operations facility. Underwater habitat Underwater habitats are underwater structures in which people can live for extended periods and carry out most of the basic
