Massive Jellyfish Washes Ashore in Maine

Beachgoers in South Portland, Maine, are being warned about a massive lion’s mane jellyfish found recently at Willard Beach. Known for their painful sting and huge size, these jellyfish can grow tentacles longer than a blue whale—up to 120 feet.

A Facebook post from the city read: “Spotted this weekend at Willard Beach: A nearly 5-foot wide lion’s mane jellyfish!” Officials warned not to touch it: “They sting; Observe it. They’re so interesting to watch, and pretty too.” Lifeguards can help return them to the water if spotted ashore.

Dangerous Stings

The lion’s mane jellyfish delivers a strong sting, even when washed up and not moving. The Wildlife Trust warns: “They can give a very nasty sting, so consult a doctor if swelling or weals are severe.”

Unusual Size and Frequency

Nicholas Record, a senior scientist at Bigelow Laboratory, has tracked jellyfish sightings in the region since 2014. He noted a sharp rise in both the number and size of lion’s mane jellyfish. “In a typical year, the biggest ones…are typically the size of a dinner plate,” he said. “This year…I’ve gotten several reports of some that are two feet and a couple that are five feet across.”

Not New, But More Noticeable

Although common in sub-Arctic waters like the Gulf of Maine, their sheer size this year has caught attention. “They’re not new to the Gulf of Maine…but the size and just the fact that they’re all we’re seeing this year is what makes it unique,” Record explained.
