Bioturbation
Any animal that lives in or on sediments – that digs or burrows or simply moves across the surface – will create some kind of disturbance in those sediments.
In the broadest sense, any kind of sediment disturbance is bioturbation. Often, however, the term is employed more restrictively to refer to the disruption of fine sedimentary layering by digging organisms.
