What makes jellyfish come to shore

Kinda like mosquitoes, right? But the truth is they are an important part of the marine ecosystem. They use their specialized, envenomed stinging cells to paralyze or kill the smaller organisms they eat.

A sting-and-swim, if you will. Interestingly, the severity of a jellyfish sting depends on several factors. Even though their stings are rare here, there are two other types of jellyfish that inhabit our waters and prove more problematic: the sea wasp, or box jelly, and the infamous Portuguese man-of-war.

Stings from these jellyfish are severe enough that they sometimes merit hospitalization. First things first, you need to remove any tentacles that may still be stuck to your skin. Repeat after me: tentacles are bad. As long as the tentacle is making contact with your skin, it will continue to discharge venom.

If you want to be as prepared as possible when you head to the beach, toss any of the following in your beach bag: vinegar, sugar, or meat tenderizer.

These substances are known for taking some of the sting out of jellyfish encounters. After a few hours in the sun, the jellyfish is merely a faint imprint on the sand.

What happens to beached jellyfish? The intense warming continued through , tampering with every level of the marine food chain and resulting in mass die-offs of seabirds, baleen whales, sea lions and other creatures.

According to the new study, it's likely that the blob drove the mass die-offs of by-the-wind sailor jellyfish reported during those years. The catch is, those warming ocean waters may have actually been good for the jellies, the researchers said. As the blob increased ocean surface temperatures, certain fish such as northern anchovies benefited from longer spawning seasons, providing more food for Velella jellies to gobble up earlier in the year.

This may have caused jellyfish populations to spike before seasonal wind changes blew the jellies ashore in the spring. Images of melt: Earth's vanishing ice.

In other words, the blob may have helped Velella jellies thrive off the Pacific coast, leading to much larger stranding events those years.

The sailor jellies could therefore become climate change "winners" as global warming is predicted to increase the frequency of marine heat waves, the researchers wrote. But their success will come at the expense of other, less fortunate creatures — and a whole mess of jellyfish carcasses on our coasts.
