Animal locomotion many of these same principles may be applied to climbing without trees, such as on rock piles or mountains. The earliest known tetrapod with specializations that adapted it for climbing trees, was "Suminia", a synapsid of the late Permian, about 260 million years ago. Some invertebrate animals are exclusively arboreal in habitat, for example, the tree snail. "Brachiation" (from "brachium", Latin for "arm"), is a form of arboreal locomotion in which primates swing from tree limb to tree limb using only their arms. During brachiation, the body is alternately supported under each forelimb. This is the primary means of locomotion
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
