Giant Jellyfish with 100-Foot Tentacles Return to Gulf of Maine Waters; Can Still Sting After Death
The large jellyfish can still sting when dead, and experts say some can wash up on New Hampshire beaches through the end of fall.
Lion's Mane jellyfish have returned to the Gulf of Maine, with tentacles that can grow more than 100 feet long. The large creatures are appearing in New Hampshire's coastal waters.
Sam Rutka, lead aquarist at the Seacoast Science Center, describes them as "bizarre and alien-like." Although they typically inhabit deeper, colder waters, winds and currents sometimes bring them close to shore.
Stings may cause a rash similar to fiberglass contact. Experts advise washing the area with salt water and applying heat or white vinegar, but warn: "You should never, ever use urine."
Officials emphasize jellyfish "don't want to interact with you," though even dead creatures can still sting. Swimmers should avoid contact and notify lifeguards if they spot one washed ashore.
A 2010 mass stinging event at Wallis Sands in Rye, New Hampshire, affected more than 100 people. Jellyfish are expected to remain in the area through the end of fall.
