CAPE CANAVERAL and COCOA BEACH, Florida – Small, circular sea creatures with ‘spokes’ extending outwardly are washing ashore on Brevard County beaches.
Blue Buttons (
Porpita porpita) are catching the prevailing southeasterly winds that have already blown ashore
Portuguese Man-o-War, Blue Dragon Sea Slugs, and
By-the-Wind Sailors onto Florida’s east coast.
Blue Buttons aren’t
jellyfish. They are Chondrophores – a colony of colony of hydrozoan polyps that only appear to be one marine animal.
Although they are similar to Portuguese Man-o-War, Blue Buttons do not have a powerful sting to humans. Instead, their venom produces a slight itchiness to people who are not allergic to the toxin.
Blue Buttons feed on crustacean larvae. Their natural predators are
Blue Sea Dragons.
