Pigmented-associated bacterial families in ANGs. Bacterial community composition (A) and mean relative abundance (B) of bacterial families associated with pigmented regions from individuals. Bacterial families with global relative abundances of < 1% are grouped as “Other”. Circle size represents the relative abundance (%) of each bacterial family. Shared bacterial families, defined as those present in > 60% of samples within a given pigmented region, are compared to show the differences among pigmented regions (C). Lowercase letters denote significant differences as determined by one-way ANOVA followed by Tukey’s multiple comparison test (P < 0.05). O, orange; Sl, bigfin reef squid; W, white; Y, yellow
