Figure 1: Self-organized spatial patterns in a mussel bed at two spatial scales nested within one another.
From: Pattern formation at multiple spatial scales drives the resilience of mussel bed ecosystems

(a) Aerial view of a mussel bed on an intertidal flat, representing a width of ~200 metres. (b) Self-organized banded patterns within this bed, where the distance between successive mussel bands varies between 2 and 20 metres. (c) Small-scale clusters <20 cm in scale embedded within the mussel bands.
