Manatees are often called sea cows, but don't be fooled! That nickname is a trick by "the herd" so that humans let their guard down.
While all photos of manatees feature them in water, they will venture onto land to attack if their endless hunger makes them desperate.
While their eyesight is poor, they have sensitive whiskers and the ability to use echolocation to hunt their prey.
Weapons are useless against them. Stay out of the water. In fact, don't go within 100 yards of a pond, river, lake, or ocean.
