The Friends of the US Virgin Islands National Park took this picture of a friendly Manta Ray greeting swimmers at Francis Bay on St John, USVI.  Graceful and beautiful.  The manta ray swims close to shore and did not seem to mind the two legged visitors to her water. This is actually a 'juvenile' since the fully grown might have a span up to 20'!  It is worth a visit to St John just to see her!
