Tensegrity structures are structures that are suspended using a combination of rigid and compressional components, usually a series of rods and strings that give the illusion of a floating object held down by the strings, which subverts people's expectations about what is physically possible. [[wikipedia:Buckminster Fuller|Buckminster Fuller]] coined the term [[wikipedia:Tensegrity|tensegrity]] from the words "tensional integrity" ([https://doi.org/10.7556%2Fjaoa.2013.113.1.34 see here]), and Steve Mould describes the mechanism in [https://youtu.be/0onncd0_0-o?si=-S-QMrZffi9L06ky this video].

[[Randall]] makes the claim that there are animals which use tensegrity in their anatomy, naming the (fictional) "Buckminster's Giraffe" as an example. The panel shows the legs of the {{w|giraffe}} using a structure similar to that of a tensegrity table. Some people consider the giraffe to be an example of a body form that appears to defy their expectations of biophysical laws because of their unusually long legs and neck as compared to the body.

[https://www.physio-pedia.com/Biotensegrity Biotensegrity] does study the role that tensegrity plays in living organisms, such as plants and animals. However, this is at cellular level, rather than the macroscopic level shown in the comic.

The title text points out that it can be argued that humans (and other vertebrates) use tensegrity in our anatomy, since we're held up by the combination of compression in our bones and tension in our muscles. Randall, however, argues that this misses the "defining characteristic" of a tensegrity structure, which is that the mechanism support isn't immediately obvious, causing people to say observer to say "WTF, how is that thing floating" . Humans, thanks to our skin and other various layers, outwardly look like a single solid structure, making the tensional forces less obvious and less impressive.

:[Cueball stands at the left of the panel, and at the right is a giraffe-like animal whose legs appear to be made of a tensegrity structure, with disconnected segments held together by strings]

:While tensegrity is rare in the animal kingdom, a few species, such as Buckminster's Giraffe, are known to employ it.
