GALVESTON, Texas - The waves are washing up something to look for on Galveston's beaches.

Portuguese Man O'Wars, relatives of jellyfish, are up and down the beaches. These critters are a concern for beach-goers because even if they're dead on the beach, they can still sting.

The timing is bad, with spring break coming up for Houston schools next week.

City leaders say there's not much they can do to clean up the Man O'Wars.
