Sialic acid levels in pomacentrids various organs confirm a decrease specific to A. ocellaris mucus. A Neu5Ac levels in A. ocellaris organs (mucus, skin, muscle, liver, digestive tract, and brain). A non-parametric Kruskal–Wallis test (p value = 9.8e − 11), followed by a pairwise Wilcoxon rank-sum test, was performed to compare Neu5Ac levels between A. ocellaris organs. Organs displaying different letter are significantly different. B Neu5Ac levels in A. ocellaris, C. cyanea, and C. viridis organs (mucus, skin, muscle, liver, digestive tract, and brain). Depending on the organ, a one-way ANOVA or a non-parametric Kruskal–Wallis test was performed, followed by a Tukey HSD or a pairwise Wilcoxon rank-sum test to compare Neu5Ac levels between the three species for each organ. Significant differences are displayed by a star (*). Data are presented in Additional file 6: Table S2
