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.

There are three species of manatees: the West Indian, the Amazonian, and the African manatee. The West Indian manatee, which includes the Florida manatee, can grow up to 13 feet long and weigh over 1,000 pounds. These peaceful creatures spend most of their time grazing and napping. They have no natural predators, but human activity poses a major risk. Boat strikes are a leading cause of injury and death, as these marine mammals are too slow to dodge speeding vessels. Habitat loss and pollution also threaten their survival. Conservation efforts, including speed limits in manatee zones and habitat protection, have helped, but these sea cows still need all the support they can get.
