According to their website, the Riverhead Foundation is “dedicated to the rescue, rehabilitation, and release of seals, sea turtles, whales, dolphins, and porpoises.”
Last November, another young harbor seal was rescued off the coast of Montauk after being spotted by someone on the beach.
At the time, it appeared the seal may have been bitten by a shark.
