VOLUSIA COUNTY, Fla. – Despite what the name implies, sea butterflies aren’t as nice as they sound.The mini marine organisms are a pteropod called cresis acicula and because of their needle-like shape, the tiny sea snails have been known to poke unsuspecting beachgoers and cling to their bathing suits.That was the case Tuesday in Volusia County, which prompted a purple flag to be flown.“They are non-venomous and are more of an annoyance than anything, they can be rinsed off with water,” Volusia County Beach Safety Ocean Rescue Captain Tamra Malphurs said in a news release.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.
