What Swimmers Need to Know About Jellyfish


Often when non-swimmers find out I’m an open water swimmer, their first question is, “Aren’t you afraid of sharks?”

Frankly, no, I’m not that worried about sharks. This is because I tend to avoid areas where sharks are likely to congregate (near seals, sea lions, and schooling fish’s favorite food) and I know that I am not actually in those environments. menu.

No, sharks don’t scare me, but jellyfish now haunt my nightmares.

Over the nearly 30 years I’ve been swimming long distances in open water, I’ve had the misfortune of getting entangled with many jellyfish, but they always make me cringe.

The worst was a failed attempt in the North Channel in 2013, when he endured a stinging onslaught of spiny lion’s mane jellyfish for more than five hours. Every time I got stung (and because I spent most of my time underwater swimming in a soup of disembodied nematocysts called nematocysts, there wasn’t an inch of my body that didn’t get stung), I felt… I did. The searing shock of electricity made the frigid water feel even colder. Eventually those stings came back to me and I had to quit the swim about halfway through.

No, I don’t consider sharks to be my enemy. But the brainless gelatinous jelly that ruins an otherwise great swim is the enemy I’m prepared to face every time I swim in the ocean.

This is because vinegar “may release more toxins from the nematocysts.”

What I would like to point out here is that Portugal’s Mano War Strictly speaking, it’s not a jellyfish. They are a type of siphonophore, a cluster of genetically identical entities that work together as a floating colony of pain. Nevertheless, they are often lumped together with jellies because their squishy bodies and behavior resemble many other types of jellies, and they can cause similar mayhem.

There is a gender. Nearby beaches facing open ocean or beaches with stronger tidal currents that push these creatures.

When venturing into a swimming area for the first time, it’s a good idea to talk to locals (swimmers, boaters, lifeguards, anglers, and other waterway users) beforehand to learn what to look out for while out and about. It is important. There. Other open water swimmers will be able to tell you where jellyfish tend to congregate and where you can swim with less critters.

Some types of jellyfish reach their peak in early summer, while others prefer later seasons. Some surface in the evening, while others just float around all day. This goes back to knowing the main species you’re likely to encounter in a particular location, how they behave, and when they’re likely to disrupt your swimming session.
