Alaska may have its own version of the Loch Ness monster, according to prominent cryptozoologists who say a video shows a mysterious marine animal, which they believe is a Cadborosaurus.
Meaning "reptile" or "lizard" from Cadboro Bay, Cadborosaurus willsi is an alleged sea serpent from the North Pacific and possibly other regions. Accounts generally describe it as having a long neck, a horse-like head, large eyes, and back bumps that stick out of the water.
The footage, shot by Alaskan fishermen in 2009, will make its public debut on "Hillstranded," a new Discovery Channel special that will air Tuesday evening at 10 p.m. ET/PT.
"I am quite impressed with the video," Paul LeBlond, former head of the Department of Earth and Ocean Sciences at the University of British Columbia, told Discovery News. "Although it was shot under rainy circumstances in a bouncy ship, it's very genuine."

LeBlond, co-author of the book "Cadborosaurus: Survivor from the Deep," said the animal is "the least unlike a plesiosaur," referring to carnivorous marine reptiles thought to have gone extinct at the end of the Cretaceous Period.
Sightings of Cadborosaurus have been reported for ages. In 1937, a supposed body of the animal was found in the stomach of a whale captured by the Naden Harbour whaling station in the Queen Charlotte Islands, a British Columbia archipelago. Samples of the animal were brought to the Provincial Museum in Victoria, where curator Francis Kermode concluded they belonged to a fetal baleen whale.
The animal's remains, however, later disappeared. James Wakelun, a worker at the whaling station, last year said that he saw the creature's body and "it wasn't an unborn whale."
Like other cryptids — animals whose existence is suggested but not yet recognized by scientific consensus — Cadborosaurus has otherwise existed only in grainy photographs and eyewitness accounts. The 2009 video, therefore, "adds to its authentication," LeBlond said.
John Kirk, president of the British Columbia Scientific Cryptozoology Club, agrees. In an issued statement, Kirk described the video as being "important. They (the fishermen) simply don't know what they have got in terms of the creatures in this video."
While many have speculated that Cadborosaurus is actually a frill shark, a large eel, or some kind of fish, LeBlond counters that it cannot be a fish due to the way Cadborosaurus moves.
"It must be a mammal or a reptile, since it oscillates up and down in a vertical plane, which eliminates sideways-oscillating fish," he explained.
A possible new believer in Cadborosaurus is Andy Hillstrand of "Deadliest Catch" television show fame. He told Discovery News that he might have seen the enigmatic animal while filming "Hillstranded," the Discovery Channel special that features the 2009 footage.

Hillstrand and his brother Johnathan traveled to sites in Alaska where Cadborosaurus has been spotted. Referring to one location, he said, "We saw a big, long white thing moving in the water. We chased it for about 20 minutes."
"Spray came out of its head," he continued. "It was definitely not a shark. A giant eel may be possible, but eels don't have humps that all move in unison. I've never seen anything like it before."
Hillstrand speculates that whales, following salmon, might be pushing the animals closer to shores and in the view of humans.
While he understands the controversy and skepticism over such sightings and claims, Hillstrand believes the many fishermen who have reported seeing the animal "are not a bunch of fruitcakes. These are people who are familiar with the local marine life."
In order for a cryptid to gain scientific credibility, more physical evidence must be obtained. LeBlond said, "We cannot go out in the ocean poking everywhere, but we are always on the lookout for new accounts."
Hillstrand, on the other hand, isn't ruling out another Cadborosaurus-related trip.
"We live in Alaska, so we might investigate Cadborosaurus again in future," he said. "We are always up for an adventure."
