Life below the surface
Manatees don't rush through life—they float. These gentle giants of the sea have been gliding through warm waters for millions of years, minding their own business and munching on seagrass. But despite their laid-back nature, they face serious threats. Hence, the last Wednesday of March is dedicated to them—Manatee Appreciation Day.
