Some fishermen were off Cape Cod looking for tuna when they spotted a different kind of sea creature.
Alex Wyckoff recorded video of several killer whales while on board the Fish Box with Matt Ward, Mark Ward and Captain Justin Daly. They shared it with the Atlantic White Shock Conservancy.
"While tuna fishing 12 miles off Chatham, [Massachusetts], directly north of the BC Buoy, we came across a pod of orcas," the fishermen said, according to the conservancy. "It was hard to count exactly how many, but there were definitely 4 different whales."
According to the fishermen, one of the whales was much bigger than the others, and that the group swam right next to the boat.
Marine biologists at the New England Aquarium say orcas have a much smaller population on the East Coast than on the West Coast, and that it's likely this orca pod is centered around Newfoundland and Labrador.
This is the second orca sighting this season; a male orca named Old Tom was spotted off Cape Cod's elbow in early July.
Experts say that there is no indication that the orcas visiting these waters are feeding off of Cape Cod's seal population.
