Swimming with Manatees (USA). 'These lumbering, intelligent creatures seek Florida’s warm-water springs and rivers each winter, and many places offer the chance to snorkel beside them as they chew sea grass and nuzzle their children. Top of the list, though, is Kings Bay, near Crystal River on the Gulf Coast, where upwards of 500 may gather on a cold January day.'
A beautiful Manatee, head and back layered with barnacle-like crust (James A. Sugar) - I adore these gentle creatures... They are listed as Vulnerable and are at greatest risk in areas, like Florida, where they come into frequent contact with humans and boats.
