Bioengineered organisms large and small, including bacteria, neogens, biological robots etc, designed to act out specific tasks and functions. Biobots of some form or another have been used since the middle information period for nanotech (bionano), production, monitoring, medicine and much more.
In the Current Era biobots of all scales are very commonplace, and are often found performing tasks assigned to them by local modosophonts and transingularity entities. They are often sophisticated entities capable of independent self-replication (under strict regulation) and often are capable of surviving in the wild as independent subsophont animal-like organisms.
Biochauvinism - Text by M. Alan Kazlev The prejudice that biological systems have an intrinsic superiority that will always give them a monopoly on self-reproduction and intelligence over aioids and mechanoids. Many radical anthropist and bioprimist groups are biochauvinist to a greater or lesser extent.
