had bad times as a kid with a "caravela". its just like this...
it actually dosn't sting. but its tentacles are toxic as fuck and will leave burn marks where they get attached. hurts alot... check "caravela queimadura" on google, we had plenty of those in beaches.. on the sand you will see those "transparent blobs", but they actually dosnt hurt. just keep away from tentacles stuff lol
btw... nice pictures.. damm
That would suck to get stung by those things too.
