manatee

Definitions

• A large, herbivorous marine mammal with a rounded, flat tail, living in shallow coastal waters and adjacent rivers of the Indian, Pacific, and Atlantic Oceans.
  A gentle titan of the sea, the manatee glides like a whimsical shadow, a guardian of the serene aquatic ballet, writing water's poetry with each languid flick of its broad, dreamy tail.
  Example: We spotted a manatee slowly grazing on seagrass near the shore.
