List of fish taxa identified across surveys of the coral reef ecosystems of the U.S. Pacific islands. Taxa are organized alphabetically by family, and alphabetically within family by lowest identified level (typically species). Trophic classifications are provided in coarse groups based on major diet items integrated across the life stages of each species. The four groups are Primary Consumer (including herbivores and detritivores), Secondary Consumer (including invertivores, corallivores, and omnivores), Planktivores (primarily consuming zooplankton), and Piscivores (including species with fish as the dominant diet item).
