What is this blue bubble with tentacles in Hawaii?
Over the weekend, I had the unpleasant ordeal of being stung by the infamous Portuguese man-o-war (Physalia physalis). Although beautiful, these marine invertebrates are to be avoided at all cost!
What is a “man-o-war”? Are Man o’ War a jellyfish?
Feeling like a jellyfish sting, Man-o-war are NOT jellyfish. The Portuguese man o’ war is a siphonophore which means it’s a colony of the same organism called zooids/polyps, rather than a singular organism like a jellyfish! They are also found at the surface of the water thanks to a gas bubble. The venomous Man-o-war is named after a Portuguese military ship because when the ship opens its masts for sailing, it resembles a fully grown man-o-war (or vice verse).
Is Man-o-war Deadly?
The Portuguese man-o-war packs a vigorous-laser-like sting once coming into contact with bare skin and have been known, although very rare, to cause cardiac arrest leading to death with certain individuals, amongst other complications.
Dead specimens are dangerous even after the air bubble is popped; tentacle pieces can still be active with venom up to a few days. The initial, excruciating pain lasts 1-3 hours, in my experience in about a 1hr, the immediate pain began to lessen after taking care of it.
With a constant looming presence in Hawaiian waters, The University of Hawaii Manoa performed in-depth research on the best way to treat a man-o-war sting.
HOW TO TREAT A MAN O WAR STING?
1) Clean the affected area with vinegar.
2) Apply a warm pad/towel/ or water across the area for 45 minutes.
“The best way to treat a sting from a man o’ war is to rinse the wound with vinegar to remove any residual stingers or bits of tentacle left on the skin, and then immerse the wound in hot water—ideally at a temperature of 113 degrees F (45 degrees C)—for 45 minutes” – Gizmodo
THINGS TO AVOID:
Alcohol, caffeine, exercising, aerobic activities.
THINGS TO DO:
Lay down and Rest! After a couple of hours or less (typically within 1 hour), the pain will subside. If you prefer, you can do what I’ve been doing: applying coconut lotion. Whenever I’m itchy I rub natural oils or coconut lotion to suppress the urge to scratch!
Luckily, a common myth we grew up with on the Islands is to pee on a jellyfish or man-o-war sting so yes, avoid peeing on the stung area also; it’s just the warmth from the pee that alleviates the pain temporarily.
For a scientific approach to taking care of your wounds, The University of Hawaii professors helped create “STING NO MORE” – a rapid relief for jellyfish and insect stings. Something similar would be this ointment for a jellyfish sting.
Where are they found?
South shores in summer months. However, Jellyfish and man o’ war are constant year-round in Hawaii. Check out this useful Box jellyfish calendar, here.
Unlike man-o-war, the box jelly navigates purposefully toward a light source where the man-o-war is guided by the ocean waves, currents, winds, and tides. However, it’s a good idea to keep track of the moon phases as the man-o-war has been observed to arrive between 6-8 days after the full moon.
In conclusion, if you see one of these Man o’ war on shore, it’s best to avoid them. Let others around you know that they are around because if you see them on the beach, it’s more than probable you will find more than a handful in nearby waters. It is possible to grab the organism by it’s “head” (the bubble area) if you want to move it safely out of a foot-traffic area. The tentacles can be very long and similar to a thin piece of hair that sticks to our human skin like velcro! So again, be wary when around these blue floating bubbles of pain and take immediate precautions.
A-not-so-fun-fact: The Portuguese man o’ war tentacles can reach a length of 160+ feet/ 48 meters.
HOW IT FEELS BEING STUNG BY A MAN O WAR
I was stung on my right forearm by a Portuguese Man o’ war while surfing on the South Shore of Oahu in May 2019. I felt it immediately but my initial thought was a fishing line got caught on my arm. Split seconds later, I felt searing and intense pain similar to getting burned.
This was my 4th time I remember encountering these unpleasant creatures. After rubbing any remaining tentacles off with the salt water, I figured it wasn’t that bad and I could still surf….big mistake: My arm began throbbing intense pain as I assume the venom was pumping into my veins, where immediately after that my right pec felt tightened as if the muscles were trying to bench press. My chest began to feel like it was getting tighter and a bit more challenging to take full breaths.
Once finally getting onto the shore, I rinsed my board and myself (wound included) with fresh water, from the beach showers, to rinse off any remaining tentacles (try to rinse it all off in the ocean without using fresh water). Through intense pain and heart palpitations, I made it home.
About 30 minutes after getting stung, I put alcohol (avoid) which relieved the pain for me immediately. After making sure it was clean, I jumped into a warm bath where the pain finally subsided to the lowest since being stung.
About an hour and a half after getting stung, the pain settled down and became tolerable. I personally applied coconut lotion from Walmart which helped tremendously and soothed the pain or whenever it became itchy. The entire healing process took 1 week from the day to be fully healed.
