Millions of Jelly Fish in Waters in the Azores Islands

We live on the island of Sao Jorge, Azores (9 islands in the archepelatio). They are midway between Portugal and the U.S.'s east coast. This year has been an outrageous year starting as early as March we started seeing a LOT of jellyfish. 2 days ago i finally got stung badly by one. There are also very odd looking jellyfish in fact that we have never seen here before. There are a number of theories about why we are experiencing this problem including the Japanese slaughter of a bunch of jellyfish and the sperm and eggs meshing together creating new subspecies. I don't know if the theories are legitimate as to why there are so many or not. Another person from the island of Sao Miguel is reporting the same phenomenon. Pelagia noctiluca (all different types), ctenophores, moon jellyfish and some Portuguese man of wars. I found pictures of a lot of them on line but I'm not sure how to share them with this group.
