Here’s everything you need to know about jellyfish at the beach:ĭespite their name, jellyfish are not fish (nor are they made of jelly). Jellyfish are actually related to corals and sea anemones, and are part of the phylum cnidocytes. These creatures are actually made up of about 95% water. They do not have brains, blood, or hearts, though they do have nervous systems that help them respond to their surroundings. ![]() They float with the current, which means that if the current comes to shore, jellyfish may come too. Stormy weather and strong winds can also bring jellyfish to shore, and they can end up on the beach. Because they contain so much water, Jellyfish die quite fast after they wash up on a beach. Jellyfish don’t generally intend to sting humans. They mostly use their stinging tentacles to catch and eat their dinner.

It’s also possible to be stung by a dead jellyfish that has washed up on the shore, so always watch your step on the beach.

Nevertheless, they can deliver painful stings.Ĭlimate change has caused rising ocean temperatures, which are changing where certain dangerous jellyfish can be found. The Portuguese Man-of-War has increasingly been spotted around Canada’s east coast, in Nova Scotia, and area where they are not native.īeaches in some countries, have jellyfish presence indicators, like like JellyWatch, and some beaches (such as those in Israel), post warning signs and provide digital tools that let people know if there are jellyfish in the waters, and in what quantities. ![]()
