The clinging jellyfish was first confirmed in New Jersey in 2016 in the Manasquan River at the Point Pleasant Canal. The DEP has been working with Montclair State University in studying the possible distribution of clinging jellyfish in New Jersey.
Montclair researchers this week confirmed the presence of about 15 clinging jellyfish of varying sizes off a private dock in the Metedeconk. Genetic testing is being conducted for final verification.
We don’t know how long they’ve been here. They might have been here for decades and nobody’s actually seen them. They’re very, very small – size of a dime, size of a quarter is about as big as they get – but they’ll put you in the hospital.
