manateeA manatee has a face only Mother Nature could love. Once you meet a manatee, you’re hooked. As the official marine mammal of the state of Florida, manatees are nearsighted, slow-moving herbivores that average about 10 ft in length and weigh in at roughly 1,200 lbs. Amazingly, considering their size, manatees are remarkably gentle. They are not territorial and they have no natural enemies and no known agenda; they pretty much just swim, sleep and eat. Small numbers of them do frequent the Weeki Wachee River, where they may swim the entire length of the river and into the spring.
