In this video from Nature, learn about the diverse life in Florida’s springs. Due to the warmth of the water, Florida’s springs teem with life from migrating sardines to mangrove snappers, a salt-water fish that cannot normally survive in fresh water. Migration to the water attracts various predators including eagles, osprey and alligators. As a life-or-death measure, the very gentle manatee takes refuge in the warm waters that rarely dip below 68 degrees Fahrenheit.
