just did a quick search myself to see. (cause it's fun) says lions manes are the largest known species of jellyfish. the biggest came in at over 7ft in diameter. some of the pictures of them are amazing.

but from comparing the pictures. while this does look similar in many ways. there's something off about it. i think its the coloration and fullness of the tentacles.

edit on: this might help. "Take note of the appearance of a lion's mane jellyfish. The bell of the lion's mane jellyfish has eight distinct lobes. The bell usually has a brightly colored pigment ranging from red to orange to yellow. Sometimes, the bell can appear magenta or purple in color as well. Lion's mane jellyfish have brown or red colored oral arms and eight separate clusters of long tentacles."
