Coral Reef
Hawaiian Islands, Central Pacific Ocean
Description
Hawaii's coral reefs are among the most isolated reef systems on Earth, with 25% endemism in reef fishes. Geographic isolation has created unique trophic relationships, while monk seals and green sea turtles serve as apex predators and large herbivores. These reefs face threats from coral bleaching, invasive algae, and fishing pressure.
