Unnamed spotting


The center is about 2 inches in diameter with blue tentacles. Kind of slimey looking like a jellyfish.




Found several of these while walking on the beach this morning... Could it be a baby portuguese man-o-war? Also saw a full grown man-o-war (I think - photo also attached!) washed up on the beach with similar coloring so just wondering...

Blue button!

Someone I know spotted one of those last summer in South Carolina. She looked it up back then and discovered its from the Pacific. Must have hitched a ride through the Panama Canal...

You are both correct, thank you for solving the mystery and for sending the links...very cool! I walk on the beach all the time but have never seen one until today. Nice to know what it is! :-)

It's not actually a jelly, but a hydrozoan called a Blue Button. The Portuguese Man-o-war has a very distinctive sail-like structure that makes it pretty unmistakable.

This looks like the same thing, right? Someone says it's a blue button jelly (Porpita porpita).

Wikipedia says it's not actually a jellyfish at all.
