Animal echolocation. A depiction of the ultrasound signals emitted by a bat, and the echo from a nearby object. Echolocation, also called bio sonar, is a biological active sonar used by several animal groups, both in the air and underwater. Echolocating animals emit calls and listen to the echoes of those calls that return from various objects ...

[1] It is a field of musicology and zoology, and is a type of zoosemiotics. Zoomusicology as a field dates to François-Bernard Mâche 's 1983 book Music, Myth, and Nature, or the ...
Known instances of rotation in biology. There exist two distinct modes of locomotion using rotation: first, simple rolling; and second, the use of wheels or propellers, which spin on an axle or shaft, relative to a fixed body. While many creatures employ the former mode, the latter is restricted to microscopic, single-celled organisms. [2]: 396.

Mitotic cell rounding is a shape change that occurs in most animal cells that undergo mitosis. Cells abandon the spread or elongated shape characteristic of interphase and contract into a spherical morphology during mitosis. The phenomenon is seen both in artificial cultures in vitro and naturally forming tissue in vivo.
Micrograph showing condensed chromosomes in blue, kinetochores in pink, and microtubules in green during metaphase of mitosis. In cell biology, the spindle apparatus is the cytoskeletal structure of eukaryotic cells that forms during cell division to separate sister chromatids between daughter cells. It is referred to as the mitotic spindle ...
