West Indian manatees are large,  gray, aquatic mammals with a body that tapers to a flat, paddle-shaped tail. They are protected by various laws and are in danger most by collisions with boats and boat propellers that venture into their shallow or calm waters they tend to slowly swim, feed and live in. They are seen as gentle giants in the water. They are approximately 10 feet tall as adults and migrate towards warmer waters in the colder seasons. You can see some in the winter season, for example, by the Tampa Electric power plant station, as those waters by it are warmer than in the rest of Tampa Bay. You can also see manatees, for example, at Crystal River and by Homossassa Springs Park in Florida, as the water temperatures are favorable for manatees to enjoy. Manatees eat aquatic plants, bear one live calf every 2-5 years typically, must rise to the water surface to breathe every 3-5 minutes, and can live up to approximately 60 years.
