The clinging jellyfish, a quarter-size species that packs a powerful sting, has returned to New Jersey waters, and scientists are scouring local waterways to see if it is present in Ocean County.<\/p>\n

No clinging jellyfish have been found in Barnegat Bay or any of Ocean County\u2019s rivers, the state Department of Environmental Protection said, however\u00a0a total of 17 small adults were identified from the Shrewsbury River in Monmouth County during a sampling that took place\u00a0Friday, June 2.<\/p>\n

Montclair State University is resuming the second phase of a DEP-funded study of clinging jellyfish, a small, invasive jellyfish that packs a powerful sting, which was first spotted in New Jersey waters last year. It was originally found in the Manasquan River (and there were anecdotal reports about it being found in northern Barnegat Bay) but it was discovered to be most prevalent in the waters of northern Monmouth County.<\/p>\n

The clinging jellyfish is not known to inhabit ocean beaches or other sandy areas, but tends to attach itself to submerged aquatic vegetation and algae in back bays and estuaries \u2013 areas not heavily used for swimming, the DEP said in a statement issued Tuesday.\u00a0The jellyfish is an invasive species from the Pacific, and its presence in Atlantic waters is not fully mapped. Multiple stings from the clinging jellyfish can cause \u201cacute respiratory problems, joint pains, and acute dermatitis that can take days to heal,\u201d according to a report from the\u00a0Woods Hole Oceanographic Institute.<\/p>\n

\u201cThis year\u2019s individuals appear to be blooming at the same time as last year\u2019s individuals,\u201d said Dr. Paul Bologna, Director of the Marine Biology and Coastal Sciences Program at Montclair State University. \u201cThis suggests that annual blooms may become a common feature in New Jersey.\u201d<\/p>\n

Bologna, working with Dr. John Gaynor, Professor of Biology at Montclair State, will use DNA analysis of the 17 individuals collected last week to also detect early developmental forms of the clinging jellyfish that are too small to see by eye. They will use this technology to look for Gonionemus vertens <\/em>polyps, which may be attached to aquatic plants or bulkheads in the Shrewsbury River estuary.<\/p>\n

This year, seven sites within the Shrewsbury River estuary where the species was found are being sampled, as well as other locations in the Manasquan River and Northern Barnegat Bay.<\/p>\n

\u201cOne of the objectives of this continued study is to determine to what degree these clinging jellyfish are becoming established in our waters,\u201d said\u00a0Dr. Gary Buchanan, Director of DEP\u2019s Division of Science, Research and Environmental Health. \u201cThis species had not been reported previously in New Jersey before last year and appears to be mostly limited to the Shrewsbury River. The challenge now is to determine what extent the clinging jellyfish are maintaining a population in this specific estuary.\u201d<\/p>\n

Both the adult (medusa) and polyp stages of the clinging jellyfish are capable of stinging, a mechanism they use to stun prey and to defend against predators.<\/p>\n

The DEP is encouraging\u00a0the public to \u201cexercise common sense and caution\u201d during recreation in areas where the jellyfish have been discovered. Anyone wading through these areas, especially near aquatic vegetation should take precautions, such as wearing waders to protect themselves. Swimming near lifeguarded beaches is, as always, encouraged.<\/p>\n
