Analysis of the differences in the composition of the bacterial communities associated with the four jellyfish species across the genus levels. 3.3. Heat map of the top 50 genera of the bacterial communities in the four species of jellyfish. Red represents the genera with high abundance in the corresponding jellyfish species, while green represents genera with low abundance. “Others” indicates the other bacterial genera in each jellyfish species except the top 20 genera with the highest abundance.
