Ogopogo

Ogopogo or Naitaka (Salish: n’ha-a-itk, “lake demon”) is the name given to a cryptid lake monster reported to live in Okanagan Lake, in British Columbia, Canada. Ogopogo has been allegedly seen by First Nations people since the 19th century. The most common description of Ogopogo is a 40 to 50-foot-long (12 to 15 m) sea serpent.

British cryptozoologist Karl Shuker has categorized the Ogopogo as a ‘many hump’ variety of lake monster, and suggested it may be a kind of primitive serpentine whale such as Basilosaurus. However, because the physical evidence for the beast is limited to unclear photographs and film, it has also been suggested that the sightings are misidentifications of common animals, such as otters, and inanimate objects, such as floating logs
