Swimmers in Massachusetts are being warned about large jellyfish that have been spotted off the state's coast.
The Hingham Harbormaster issued a warning saying numerous lion's mane jellyfish had been seen in the town's inner and outer harbor over the weekend. At least one resident has been stung but did not require medical treatment. The lion's mane jellyfish can grow to 5 or more feet across, with tentacles more than 100 feet long!!!! ewwwwww and gross.
