Elkhorn coral

Elkhorn coral are among the most important reef-building coral found in the Caribbean and Florida. All across Florida's reefs, the corals are steadily bleaching due to the ocean's rising temperature. As the oceans warm, they also become more acidic, hampering the ability of corals to build their protective skeletons.
