Small cryptopredators contribute to high predation rates on coral reefs

摘要: Small fishes suffer high mortality rates on coral reefs, primarily due to predation. Although studies have identified the predators of early post-settlement fishes, small cryptobenthic remain largely unknown. We therefore used a series mesocosm experiments with natural habitat and fish communities identify impacts range potential predators, including several invertebrates, prey populations. While there was variability in predation rates, many members community act as facultative cryptopredators, being when piscivores larger. Surprisingly, we also found that smashing mantis shrimps may be important predators. Our results highlight diversity predatory reefs previously unknown trophic links these complex ecosystems.
