Portugese Man of War
Very interesting looking and can give a very nasty sting. We got
lucky to see several of these close up today from the dinghy. It is
very hard to see what you are shooting in the sun but I was pleased
with these photos.  Added a link so you can read about them.
 They are everywhere here this year.

Note the long tentacles that can reach up to 165 feet.  These must have been babies
only about 3 feet
