Taxonomic and function composition of host microbial communities across host classes and microbial habitats. a Internal microbiomes of terrestrial and freshwater organisms, b external microbiomes of terrestrial and freshwater organisms, and c external microbiomes of marine organisms. Each color represents a unique bacterial phylum. A legend for microbial taxa including bacterial phyla and Archaea is provided
