Reply from Raj:
Portuguese man of war are sometimes visible in Bermuda waters or near the shore mostly during spring and early summer. However, you don't see tons of them, but occasionally.
Due to storms or strong winds, they get swept towards the shore. Otherwise, these marine creatures would generally like to be in the mid sea where they can hunt for the fishes.
I would advise you to stay far away from it if you happen to spot one. Their stings can be very painful and the venom quite poisonous.
Having said that, I would also like to say that Bermuda beaches are generally very safe. Only in rare occasions will you find visitors having spotted or complaining about such man of the war.
Portuguese Man of War
For the readers:
Portuguese Man of War is a Jellyfish like marine creature that has a blue/purple color bladder that floats above the water surface. From far, it looks great and quite attractive. However, be careful! They have polyps and long tentacles that hang below the water surface. These tentacles have poisonous venom and a sting can be extremely painful and sometimes deadly. In many cases, the sting results in some form of allergic reactions.
Due to storm or heavy winds, they can get swept to the beaches. On the beach, they might appear to be dead, but in most cases they are actually not.
If stung, the first action is to avoid more stings that may further complicate the matter. Gently remove the barbs with some plastics like door key or credit cards. Apply salt water and NOT fresh water or Vinegar. If itching persists, apply 1% hydrocortisone ointment 4 times a day, and 1-2 25 mg diphen-hydramine every 6 hours. For serious problems like chest pain or breathing difficulty, you should not wait and immediately rush for proper medical treatment.
By the way, if you happen to spot one Portuguese Man of War, there are like to be more of them around the same area.
