The start of another beach season in North Carolina has ushered another timely visit from the Portuguese man o’ war, a predatory creature found in the Atlantic, but not as prevalent as its close relative, the jellyfish. Over the last weekend, officials at Cape Lookout National Seashore spotted more than one Portuguese man o war stranded on the sand by the receding tidewater.

Beach goers are warned to stay far, far away from any of these creatures, which have the ability to inflict a very painful (even deadly) sting — even weeks after the man o’ war has died.

What’s more, they can be found in a number of shapes and colors.

From atop the water, the gelatinous appearance of the man o’ war may fool you into thinking the creature is a jellyfish. It also floats and bobs on the water’s surface, much like a jellyfish.

Those long tentacles are precisely why you should steer very clear of any Portuguese man o’ war, especially if it’s seen in the water.

YouTube/Nat Geo WILD The tentacles are constantly moving underneath the water in search of prey. Whatever they come into contact with suffers a venomous sting that’s powerful enough to paralyze even large fish.

When the tentacles come into contact with human flesh, the resulting sting is quite painful and the results can be felt and seen for days.

It’s said the stings from a Portuguese man o’ war have the ability to kill a small child, especially if the tentacles wrap completely around the child’s torso.

For certain, any sightings of the Portuguese man o’ war are not to be taken lightly.

Before heading out to the beach for the day, consider checking local beach reports for Portuguese man ‘o war sightings. If you suffer a sting, seek medical assistance for your wounds.
