Chris Garmston was walking his dogs on the beach near his home in Hilton Head Island's Port Royal Plantation Christmas morning when he spotted something unusual.

Participants in the Dec. 17 Fripp Island Audubon Club's bird count had to sidestep several Portuguese man-of-wars while scanning the horizon, and their presence has recently been reported on Hunting and Daufuskie islands as well.
