As more and more people build homes near their habitats, they are crowded out. Man has now started to protect manatees by issuing manatee zones. Manatee zones are zones for boaters. Manatee zones are made to stop boaters from speeding in manatees habitats. Usually the speed limit is 5-8 miles per an hour.
Manatees depend on food that is vegetation.
They do not eat small animals. The vegetation they eat must have sunlight to grow. Manatees don't live in the wetland, but do occasionally visit there. All marine life is part of an inter-connected web.
