I'm not really sure what you mean, but if you are saying when do jellyfish wash up on the beach, they are either dead or injured jellyfish wafted onto the beach by the tide, or jellyfish who get beached while swimming too close to the surface. I hope this will help.
Jellyfish wash up on the beach because they have died
There are different types but the Pacific is full of them-they wash up on the beach all the time. Catalina island has a massive problem with jellyfish.
Yes, usually a strong, rough surf will deposit many on the beach.
I am beginning to believe it depends on the tide, it seems that they are closer to shore, that is close enough to affect swimming, when the tide is high.
leave it alone! it can sting you!
If they are completely dried up then no. If they are still moist and LOOK like they could in fact be alive or still sting you, then it is best to stay clear. Most jellyfish are OK except for the box jellyfish found mostly around and in the water of Queensland, Australia.
Yes. But rarely.
Yes it can, as long as it is alive.
It forms a beach.
Only when they wash up from the ocean
maybe because they can not swim against some waves and so they get washed up or they are already dead
They just wash up on the beach
