WATCH: Orca Killer Whale Filmed Off Cape Cod

Think that killer whales only exist off the west coast.  Think again.  They're getting closer.

This past Sunday afternoon fishermen about 70 miles off the coast of Cape Cod filmed an Orca, or "killer whale" swimming with a group of porpoises.  The huge fish swam beside the boat for about twenty minutes and one of the fishermen aboard said that they were so close that he could "smell fish."

Orca whales are mostly found around the waters of the Arctic and Antarctica, but are often seen off the west coast of the United States and Canada.  Sightings of these killer whales off the northern east coast are very rare.

The Orca eats birds, marine mammals along with other fish, and have been known to take out a great white shark.when they're hungry.

Following the sighting, a PHD. candidate at the University of Rhode Island’s Graduate School of Oceanography told the Cape Cod Times that while it''s rare to see a killer whale off New England's coast, they are here, and number about 200 between the Cape and Canada.

Will someone eventually see an Orca off the coast of Maine someday?  If so, we'd love to see the video!
