Manatees may be in many places. During most of the year, manatees may be found in fresh or salt waters, preferring calmer rivers, estuaries, bays, and canals. In the winter, manatees seek warmer waters and often congregate in the discharge areas near power plants or natural warm water springs. Boaters should avoid manatee habitat areas and use caution when traveling in known manatee travel corridors. It is illegal to harass, hunt, capture, or kill any marine mammal, including manatees. Any act that disrupts a manatee's normal behavior is punishable by a fine of up to $50,000, one-year imprisonment, or both.
