Scientists with the U.S. Geological Survey and Eckerd College recently published research on a newly discovered refuge for reef-building corals in mangrove habitats of the U.S. Virgin3 Islands. More than 30 species of reef corals were found growing in Hurricane Hole, a mangrove habitat within the Virgin Islands Coral Reef National Monument in St. John. Corals are animals that grow in colonies, forming reefs over time as old corals die and young corals grow upon the calcium4 carbonate or limestone5 skeletons of the old corals. Coral reefs make up some of the most biologically diverse habitats on Earth, and face many threats such as coastal6 pollution, dredging and disease. However, some of their most widespread threats involve warming ocean temperatures, solar radiation and increased ocean acidification. It is from these threats that corals are finding refuge under the red mangroves of Hurricane Hole. Red mangroves, subtropical or tropical trees that colonize7 coastlines and brackish8 water habitats, have networks of prop9 roots that extend down toward the seafloor, and corals are growing on and under these roots.。
