Manatees are so effective at eating their way through weed-choked canals that they have actually been employed in some countries to clear canals for people.
Manatees communicate through squeaks and chirps.
The manatee has small eyes, protected by membranes which can be drawn across the eyeballs.
The two flippers of the manatee are used to steer and position the manatee while swimming, but they are also used as arms to hold onto objects and manipulate food to the mouth. Sometimes the manatee even ’walks’ on its flippers.
