Rise in stunning, jellyfish-like creatures washing up on MS Coast beaches. Are they dangerous?
Known for their stunning colors and “balloon-like float,” Portuguese Men O’War may be interesting to look at — but don’t get too close.
Officials across the Mississippi Coast are warning beachgoers to keep their distance from the jellyfish-like creatures as sightings are likely to occur.
“Portuguese Man O’ War ‘jellyfish’ are currently being pushed onshore by southerly winds onto the beaches lining the Mississippi Sound,” Pass Christian city officials said in an April 16 post on Facebook.
Here’s what to know about Men O’ War and how to stay safe if you see one on a beach.
What is a Portuguese Man O’ War?
Portuguese Men O’War are jellyfish-like creatures that resemble an 18th century Portuguese warship, from which it got its name.
The creatures are colorful and have long tentacles that can stretch out to 30 feet, according to experts at the National Oceanic and Atmospheric Administration.
Often found in tropical and subtropical waters, Men O’ War are made up of numerous organisms — called polyps — that live together, experts said.
Are Portuguese Men O’ War dangerous?
Yes, the venom of Portuguese Men O’ War can be deadly to small fish and painful to humans, NOAA experts said.
It’s best to admire them from a distance to avoid getting stung as the creatures can sting even after they are dead and dried, Pass Christian city officials said.
How do Portuguese Men O’ War arrive at beaches?
If you see a Man O’ War on the beach, it’s likely the jellyfish-like creature was pushed on the shore by the wind, officials said.
Currently, southerly winds are causing the creatures to wash up on beaches lining the Mississippi Sound, according to officials.
What should you do if you’re stung by a Man O’ War?
Here’s what to do if you get stung by a Man O’ War, according to the Irving Medical Center at Columbia University:
- Treat right away by rinsing the venom and removing any tentacles
- Apply heat to help reduce pain
- Take over-the-counter pain medicine
- Use an over-the-counter hydrocortisone cream for itchiness
- Seek medical treatment if a deep sore develops or you have a fever, signs of weakness or joint stiffness and swelling
