The Thetis Lake Monster is a legendary humanoid fish-like creature from British Columbia, Canada. Allegedly, two teenagers claimed to be attacked by a silver, scale-covered biped at the Thetis Lake beach in 1972. One of the boys had a bloody wound left by six razor-sharp points on the monster’s head. However, the boys later admitted that their story was fabricated, but the legend lingered after several sightings of a similar creature followed.
