Be on the lookout for one of Delaware’s most dangerous “visitors”

They’re colorful, silent, warrant a closer look, and chances are you’ll probably think they’re pretty cool.

Like Lenny Ballas of Millsboro who responded “Cool, I’d go with cool, yeah, not scary.” when asked to describe the Portuguese Man O’ War.

However, these Portuguese Man O’ Wars are no joke and can cause an immense amount of pain.

According to DNREC, these jellyfish-like creatures made an unlikely appearance on Delaware beaches over the holiday weekend.

Officials say a sting from the tropical visitor could lead to a number of symptoms such as trouble breathing, fainting, and swelling of the lips or tongue.

With its colorful makeup the man o’ wars could be difficult to spot in the water.

Which is why Patrick Cooper, a regional administrator with DNREC stressed the importance of being aware of your surroundings when in the water, saying, “It’s just one of the dangers of the Ocean, you just need to be aware of it.” and “Just be aware, pay attention, and just always look around.”

The 4th of July Weekend marked the first time in at least 15 years that the species washed up on the shores of Delaware.

DNREC says they were spotted at the Delaware Seashore, Fenwick Island, and Cape Henlopen State Parks, which is why they’re getting the word out to their lifeguards and the public.

“We’ve made our lifeguards and our rangers staff aware that this is happening.” And “If you see one, or suspect to see one, don’t touch it.” said Cooper.

We’re told if you see a Portuguese Man O’ War on any beach, notify a lifeguard. And for your sake stay away, far away.

DNREC says that the tentacles on the man o’ war can grow up to 50 feet in length, packing a painful punch with every sting.

If you happen to get stung, remove the tentacle with something other than your hand and wash off the area where you were stung.

You’ll most likely have a red welt on the area for a few days after and officials say the pain could last up to an hour.
