An endangered whale shark surfaced right alongside a wildlife-watching boat roughly 100 miles off the coast of New York City this week, in what passengers and crew described as an extraordinary encounter near Hudson Canyon. The massive fish was one of two whale sharks spotted during a 24-hour pelagic wildlife trip that ventured deep into the canyon's waters. Video captured the moment one of the sharks surfaced beside the vessel, drawing cheers, clapping, and high-fives from everyone aboard.
The trip departed from Brooklyn and was operated by American Princess Cruises, according to FOX 5 New York. Naturalist Chris St. Lawrence filmed the whale shark video and said sightings like this play a crucial role in conservation efforts. One passenger's reaction, captured in the footage, summed up the mood in three words: “That was nuts.”
Whale sharks are the world's largest fish, and they typically prefer tropical seas rather than the cooler waters off the Northeast. Their appearance here has been linked to the seasonal Gulf Stream, which can push warm-water species north during late summer. Confirmed sightings have previously turned up off Sandy Hook, New Jersey, in 2014, according to National Geographic, underscoring that these are unusual visits.
Inside the Canyon That Draws the Deep-Sea Giants
Hudson Canyon, where the boat ventured for the encounter, is an immense deep-sea gorge extending roughly 350 miles seaward from a point about 100 miles southeast of New York City. It plunges to depths of up to 2.5 miles and spans as much as 7.5 miles across, making it the largest submarine canyon on the U.S. Atlantic coast, per the Mid-Atlantic Fishery Management Council. Carved by glacial runoff during the last ice age, the canyon's steep walls generate deep-water upwelling that pulls migratory open-ocean species toward the continental shelf.
That upwelling supports far more than passing whale sharks. Deep-sea corals and cold-water sponges can form nursery and feeding habitat for marine species. The canyon effectively functions as a vital feeding ground for massive filter-feeders and other highly migratory marine life passing through the region.
A Sanctuary Designation Still Pending Federal Review
Hudson Canyon is currently under consideration for designation as a national marine sanctuary, a process NOAA formally began in June 2022 following a 2016 nomination from the Wildlife Conservation Society. The nomination has remained on the agency's inventory through at least February 2027, per the NOAA Office of National Marine Sanctuaries. If finalized, sanctuary status would restrict seabed extraction and mineral development in the canyon while promoting scientific research and conservation.
The stakes for the species itself are significant. The International Union for Conservation of Nature reclassified the whale shark from Vulnerable to Endangered on its Red List in July 2016 after global populations dropped more than 50% over 75 years, driven largely by overfishing. Whale sharks are also subject to fishing regulations.
Part of a Bigger Marine Comeback in the New York Bight
The whale shark sighting adds to a string of unusual marine encounters documented in local waters this year, including a lone orca off Montauk. Marine biologists have linked some whale activity to abundant forage species, as Hoodline has reported. That activity coincided with Staten Island-based nonprofit Gotham Whale documenting its 500th individual humpback whale in waters around the city's five boroughs this past August.
Still, researchers caution against reading too much into a single sighting 100 miles off Brooklyn. Whale sharks remain endangered globally, but the encounter offers a rare and thrilling reminder of just how much deep-ocean life passes through Hudson Canyon's waters each summer.
