Structures found on meteorite fragment Allan Hills 84001. Nanobacterium (/ ˌ n æ n oʊ b æ k ˈ t ɪər i əm / NAN-oh-bak-TEER-ee-əm, pl. nanobacteria / ˌ n æ n oʊ b æ k ˈ t ɪər i ə / NAN-oh-bak-TEER-ee-ə) is the unit or member name of a former proposed class of living organisms, specifically cell-walled microorganisms, now discredited, with a size much smaller than the generally ...
A nanobe (/ ˈ n æ n oʊ b, ˈ n eɪ n oʊ b /) [1] is a tiny filamental structure first found in some rocks and sediments.Some scientists hypothesize that nanobes are the smallest form of life, 1 / 10 the size of the smallest known bacteria.
The smallest organisms found on Earth can be determined according to various aspects of organism size, including volume, mass, height, length, or genome size.. Given the incomplete nature of scientific knowledge, it is possible that the smallest organism is undiscovered.
A zoosporangium is the asexual structure in which the zoospores develop in plants, fungi, or protists (such as the Oomycota). Developing sporangia of oomycetes go through a process of cleavage in which a protein kinase , in the case of Phytophthora infestans , induces the sporangial cytoplasm to split and release the various zoospores.

A so-called "cathedral" mound produced by a termite colony. Structures built by non-human animals, often called animal architecture, [1] are common in many species. Examples of animal structures include termite mounds, ant hills, wasp and beehives, burrow complexes, beaver dams, elaborate nests of birds, and webs of spiders.
Structure of Collagen I fibrils. Collagen is the major structural protein outside cells in many connective tissues of animals. [12] As the primary component of connective tissue, it has the largest amount among protein in mammals, occupying 25% to 35% of all protein content in the body. The fibrils in collagen are packed in a crimp structure.
Microfauna (from Ancient Greek mikros 'small' and from Latin fauna 'animal') are microscopic animals and organisms that exhibit animal-like qualities and have body sizes that are usually <0.1mm. [ 1 ] [ 2 ] Microfauna are represented in the animal kingdom (e.g. nematodes , small arthropods ) and the protist kingdom (i.e. protozoans ).
Schematic diagram of the 2D structure of aquaporin 1 depicting the six transmembrane alpha-helices and the five interhelical loop regions A-E The 3D structure of aquaporin Z highlighting the 'hourglass'-shaped water channel that cuts through the center of the protein. Aquaporin proteins are composed of a bundle of six transmembrane α-helices ...
