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."
