There are things found at the beach that everybody knows to stay away from, such as sharks, jellyfish and crabs. But there are also some lesser-known sea creatures that may occasionally wash up, and it's important to be aware when you head to the beach (video below).
One of these creatures is the Portuguese man o' war. These sea creatures float in packs and follow the current, Your Nation News reports. They generally stay in the water, but can occasionally wash up onto the shore.
The animals are fairly easy to spot as they have tentacles that can reach up to 30 feet long. Some people think upon seeing a man o' war that it's just another form of a jellyfish, but that's not quite true. While the two are related, there are some distinct differences that make the Portuguese man o' war far more dangerous.
The Portuguese man o' war's sting can paralyze people and can even cause death in some extreme cases. One thing to keep in mind is that the man o' war has stinging cells which remain active after it has died, so you can still get stung badly if you touch one that, NJTV News reports.
