Like many creatures, the manatee’s bulk-they can be as much as 13 feet (4 meters) long and 1,300 pounds (600 kilograms)-belies its aquatic grace. Also called sea cows, manatees are graceful swimmers that typically glide along coastal waters at 5 to 15 miles an hour (8 to 24 kilometers an hour). This West Indian manatee is wintering in a North Florida spring, attracted by the region’s constant 72 degrees Fahrenheit (22 degrees Celsius) waters.
