They are called porpita porpitas. (or blue button jellyfish) I found them recently on the Corolla beaches.

I don't know, but they were washing up in droves in SOuthern Shores NC beach on August 14th and I haven't found anyone who knows what they are!
try jellyfish, blue-ringed octopus, man-o-war, etc.
The Blue Bottle feeds on small fish and other small ocean creatures. They capture their prey with their tentacles, where a poison is released leaving their prey stunned. The tentacles attach extremely well to their prey. If a tentacle is put under a microscope it looks like a long string of barbed wire, which shows the ability of this jellyfish to kill its prey.
The float or body of the blue bottle measures between 3 to 15 cms. The tentacles can range in length from 15 cms up to 10 metres!.
Their tentacles are not that long, reaching to lengths of 5 ft. But they are very poisonous.
how do blue blubber jellyfish feed
horrids
blue bottle jellyfish or portugeuse man of war
Oddly enough, yes. An interesting side note: When turtles eat a lot of jellyfish, they give off a pheromone that makes sharks frenzy in their presence. Often, the turtles are the main course of the frenzy. Talk about food chain cruelty.
