Jellyfish invasion at SF's Ocean Beach

SAN FRANCISCO National Park Service ranger George Durgerian said the jellyfish packed a section of the beach that stretched about three miles long and 20 feet wide, leaving many beach-goers surprised and concerned about their safety.

These jellyfish are likely to be moon jellies, which have a mild sting that rarely penetrates the human skin.

Reports said jellyfish were being kicked, rolled on and thrown around as frisbees.

Marine experts said the beaching wasn't unusual and tides were going to carry the jellyfish away.
