Mark Quartiano, known as Mark the Shark, says he's caught thousands of sharks, but never encountered anything like this.
"It's a very rare fish. It's like a big gigantic whipping stingray. It's a dinosaur," Quartiano told ABC News.
Known as a Dactylobatus clarkii, the creature measured in at around 14 feet and was caught in waters about 500 feet deep. Quartiano made the catch while shooting a series of TV shows for a Japanese network.
The fish was captured, tagged and released back into the ocean.
In October, an 18-foot oarfish was found dead in the water off Catalina Island. Then just days later, the carcass of a 14-foot oarfish washed up at a beach in Oceanside.
