Scientists sent hundreds of critically endangered corals from South Florida to the Texas Gulf Coast on Wednesday in a research and restoration project.Why it matters: Last year's record marine heatwave caused corals in the Florida Keys to expel algae that lives in their tissues that turned them white in a widespread coral bleaching event.

Scientists have moved about about 300 endangered sea corals from South Florida to the Texas Gulf Coast for research and restoration.
