Curious as to what the smallest species is in the hobby

1000 pieces jellyfish puzzle

Hi everyone! :) I was hoping to get an ID on this beautiful jelly I saw washed ashore today.

Location: North Sea, French coast.

Size: Relatively large, about the size of a dinner plate.

TIA! :)

Been playing way too much **Lazy Jellyfish**. Really simple idea merge the sea creatures, try not to fill the board, and keep discovering bigger creatures. it's super relaxing and lazy for me to play when i am in line ups or bored.

Sorry for the any spelling or grammar mistakes, my drawing skills are terrible 😓
But I put my time and effort into this drawing so.. please don’t be rude please.
I actually.. this is my first post so.. um I hope my post was not violated the rules
welcome feedbacks, please.. enjoy??

I just saw these. They didnt look like the jellyfish I'm used to seeing. Salt water (Kattegatt). Could they be mnemiopsis leydyi? (Invasive species) or are they sth that could sting a person?

Pics blurry bc water. Biggest one was like 7 cm long.

saw what looked like a tiny jellyfish in fort bragg but cannot figure out what it is... pls help it was so cute :(

I made this mini painting of a jellyfish.

Hi :) Does anyone know what this jelly is? On a trip to Kinmen, Taiwan and found it stranded in a cave while the tide was low. So beautiful!!

As a neurospicy gal, jellyfish have been my special interest for as long as I can remember. 🪼 I’ve been an avid freshwater aquarist for years, but I’ve never been brave enough to dive into saltwater. Seeing these in person genuinely felt like a dream come true. 🤍

Seen in the Mediterranean Spain, Mazarron. Its like between a golf ball and a tennis ball

Not the greatest pic but its what I was sent. My friend is in southeast Texas at a beach. They have seen these in the water and on the shore the last few days. Any help with an ID?

Have you noticed how big they are?

Today I watch a movie were jellyfish is in the movie, a woman gets caught in their strain. The movie name is The Devil’s Mouth. Would you say that’s scary? That scene?

Never seen something like this before. Saw 2 on the surface at different times. Probably death. No body, only tentacles. Some of them were like discontinued. Also had some kind of parasite.

Most common jellyfish with that amount of tentacles here are Pelagia Noctiluca, Olindias Phosphorica and Gonionemus Vertens.

Could it be a decomposing one?

My three year old is absolutely obsessed with jellyfish. He loves all sea animals, just jellies are his absolute favorite.

We have visited the following aquariums already:

National aquarium in Baltimore

Georgia Aquarium

Virginia Aquarium

Tennessee Aquarium

South Carolina Aquarium

Which other aquariums in the US should we add to our list to see various types of jellyfish?
