West Indian Manatee, Florida, 1999

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.
