The coolest thing we saw from the canoe were big friggin' flappin' stingrays, on several occasions. They flew around lazily just under the surface, and sometimes their wingtips would breech. Thanks to the marvels of the internet, we now know they are cownose rays, they don't use their stingers on people often (except that one did nearly kill the very famous James Smith, the founder of the first permanent English colony in the New World).
Shown: Francoise, Felix and Lucie shove off. Noone fell victim to the terrible sting of the cownose ray.
