  abstract = {{E}cological interactions uphold ecosystem structure and functioning. {H}owever, as species richness increases, the number of possible interactions rises exponentially. {M}ore than 6,000 species of coral reef fishes exist across the world's tropical oceans, resulting in an almost innumerable array of possible trophic interactions. {D}istilling general patterns in these interactions across different bioregions stands to improve our understanding of the processes that govern coral reef functioning. {H}ere, we show that across bioregions, tropical coral reef food webs exhibit a remarkable congruence in their trophic interactions. {S}pecifically, by compiling and investigating the structure of six coral reef food webs across distinct bioregions, we show that when accounting for consumer size and resource availability, these food webs share more trophic interactions than expected by chance. {I}n addition, coral reef food webs are dominated by dietary specialists, which makes trophic pathways vulnerable to biodiversity loss. {P}rey partitioning among these specialists is geographically consistent, and this pattern intensifies when weak interactions are disregarded. {O}ur results suggest that energy flows through coral reef communities along broadly comparable trophic pathways. {Y}et, these critical pathways are maintained by species with narrow, specialized diets, which threatens the existence of coral reef functioning in the face of biodiversity loss.},
