A large group of sea cows gathered at a power plant in the US state of Florida. The water in the drain is much warmer than in the rest of Tampa Bay. The power station extracts salt water from the bay. Clean hot water then flows back into the bay.
Florida is known for its Manatees (manatees). Most of these live on the Nature Coast, northwestern Florida. Here you have the greatest chance of spotting these colossal but gentle animals. You go on a river with an experienced guide. He knows the area well and often knows exactly where the sea cows are. With diving mask on you jump into the water and wait until the first manatee comes to you.
