Population
Manatees have no enemies, but they are killed by humans. Their population is decreasing because they are hit by boats, they swallow fish hooks, crab trap lines, and the most dreadful one is they get crushed or drown in canal locks and flood control. They also get hunted for their Hides, Oil and Bones. In January of 2011 there was a estimated 4,834 manatees! They are endangered, we need to help them!
