The survival of many microorganisms depends on their ability
to navigate through complex biological environments. Complexity may
come in many forms, from circuitous channels to non-Newtonian bulk
fluid rheology. We will discuss analytical and numerical insights into
swimming through model viscoelastic and anisotropic fluids, with a
special focus on the outsized roles played by the presence of nearby
boundaries. And we will propose a classification which seeks to
organize a multitude of systems based on the relative sizes and
timescales associated with one or many active bodies and any
surrounding obstacles, broadly interpreted.
