Marine mammal experts give tips for seeing seals on Long Island

Local seal populations are on the rise, so whether you take a guided tour or hike out on your own, there’s an excellent chance you’ll see a herd of these cute critters frolicking around Long Island’s bays and beaches.

Here are tips from marine mammal experts for finding, identifying and watching the seals from Jones Beach to Montauk.


“The populations of the seals here are on the increase,” says Arthur Kopelman, a biologist who leads seal walks for the Coastal Research and Education Society of Long Island. “Last winter for the first time they began to rebound from Hurricane Sandy,” he says. In March, when the local seal population peaks, “We’ve seen up to 200 at a time,” Kopelman says.


Although their exact place of origin is unknown, the seals most likely swim here from coastal Maine and Canada, says Melanie Meade, a marine biologist and nature educator at the South Fork Natural History Museum & Nature Center in Bridgehampton. “They are following their food, which is mainly squid,” Meade says.


Seals generally like to spend their days resting on exposed sandbars, Meade says. Called seal haul-outs, these seal sunbathing spots are in Moriches Bay and the waters off the 1 1⁄2-mile-long Seal Haul-Out Trail at Montauk Point State Park.


Harbor seals make up more than 99 percent of the population at Cupsogue, Kopelman says. They range from 4 to 6 feet long and have spotted coats and small front flippers, according to the website of the National Oceanographic and Atmospheric Administration. Gray seals, often seen in Montauk, are larger than harbor seals and have a longer, broader nose, Meade says. Arctic seals, which tend to be solitary, are also occasionally seen here.


Before going on a solo seal walk, Kopelman suggests taking a guided tour to learn how to locate and behave around these protected marine mammals.

“If you don’t know what you are doing, you have a serious chance of disturbing the seals,” Kopelman says. Seals are protected by the Marine Mammal Protection Act of 1972, which makes it illegal to feed or harass them.

“Stay 100 feet away, and don’t do anything that disturbs their behavior,” Meade says. For a closer look, bring a spotting telescope.
