If you're by the Navesink River, you might be lucky enough to catch a glimpse of the dolphins that were spotted in the last few days.

The Red Bank Green Newspaper first reported seeing four dolphins in the river, at almost the same location a pod of 16 Atlantic Bottlenose Dolphins were spotted four years ago.

There is concern by many that this new pod of dolphins could face a similar fate to the one from 2008, which saw six of the mammals turn up dead. While the warm water is suitable for the dolphins currently, there is belief that once the winter comes these new dolphins could suffer a similar deadly fate.

In the past the NOAA Fisheries Service has refused permission to anyone wanting to drive or lead the dolphins out to see, and has said the same policy will be followed in this instance.

"It makes sense to let nature do its thing," NOAA Spokeswoman Maggie Mooney-Seus told NBC 4 New York.

Dolphins are not an endangered species, and many anglers fishing along the Navesink in Rumson and Middletown have said they have seen dolphins several times throughout the summers. One fisherman noting the mammals come in for the abundant food supply from fish and bait.

The dolphins have also been spotted recently at Sandy Hook .
