Manatees crowd together near the warm-water outflows from Florida Power & Light's plant in Riviera Beach, Fla., on Friday, Feb. 5, 2021. An unprecedented, experimental attempt to feed manatees facing starvation in Florida has started slowly but wildlife officials expressed optimism it will work as cold weather drives the marine mammals toward warmer waters. Officials said Thursday, Jan. 13, 2022, that a feeding station established along the state’s east coast has yet to entice manatees with romaine lettuce even though the animals will eat it in captivity.
