Sandbar sharks are making waves across Southern New England and Long Island’s South Shore this summer as numbers have surged. Underwater video shows a brown shark—also known as a sandbar shark—swimming off Block Island, Rhode Island.
THE TAKEAWAY
- The New England Aquarium observed more than 2,000 animals during an aerial survey.
- At the start of the survey, scientists counted about 1,800 dolphins across four species.
- The team also spotted an endangered blue whale and a small group of endangered fin whales.
New England scientists observed more than 2,000 animals during a recent aerial survey over the Northeast Canyons and Seamounts Marine National Monument, highlighting the area’s diverse wildlife.

“The diversity of sightings was truly remarkable and a testament to why the monument is such a special habitat,” Katherine McKenna, an associate research scientist at the aquarium’s Anderson Cabot Center, said.
At the start of the survey, scientists counted about 1,800 dolphins across four species. They later documented a sperm whale, humpback whale, 11 whale sharks, manta rays, Chilean devil rays and hammerhead sharks.

“From regular visitors like dolphins and sperm whales, to large baleen whales drawn by aggregations of zooplankton and whale sharks and manta rays following warm Gulf Stream waters, the monument brings together an incredible variety of marine life,” McKenna said.

The team also spotted an endangered blue whale and a small group of endangered fin whales, including a mother and calf feeding just outside the monument.
“Seeing a variety of threatened and endangered species actively feeding in the monument was particularly memorable and underscores the importance of protecting this productive habitat,” McKenna said.

The New England Aquarium’s previous flight over the monument took place on July 13, 2026. During that survey, the team identified nearly 650 animals, including more than 600 dolphins, four endangered sperm whales, 23 pilot whales and a whale shark.

The monument was established in 2016 as an underwater sanctuary. The nearly 5,000-square-mile area is located about 130 miles southeast of Cape Cod.
The area contains three deep-sea canyons that provide habitat and feeding grounds for a vast array of marine species.

Earlier this year, the Trump administration rolled back protections for the monument, allowing commercial fishing in the area.
The change has raised concerns among conservationists about how increased fishing activity could affect the diverse marine life that relies on the monument.
