Wildlife Refuge, because of the river’s great significance to migratory birds and waterfowl. Mammals of the Metedeconk include those typically found at New Jersey rivers, such as river otters and beavers. Aquatic life includes many species of fish and jellyfish, including one species whose bodies are about two-inches long and appear clear in daylight, but glow blue by night. Hurricane Sandy In October 2012, under the influence of Hurricane Sandy, ocean waters directly infiltrated the south branch of the river at the area of the Metedeconk Bridge. Immediate impact of the hurricane on the river included a change in salinity of the river's ecosystem, as well as elevated contaminate levels caused by relevant water treatment facilities going temporarily off-line. The long-term impact of Hurricane Sandy on the river and its ecosystem remains an area of study.
