Officials said the mini marine organisms are a pteropod called cresis acicula, more commonly known as a sea butterfly.

Currents generated by tropical storms and hurricanes bring the needle-shaped sea snails from their usual home in the warm Caribbean waters to the Sunshine State.

Sea butterflies use their tongues to propel their cylindrical silica bodies, creating a movement that resembles a flutter.

Though they float like a butterfly, they also sting like a bee. Their sharp bodies can stick into the skin like a splinter and multiple pricks can lead to small, reddish bumps.

Officials say it's not an allergic reaction because sea butterflies are non-toxic.
