Carcass of a sea serpent found at Naden Harbour.

In 1937, what is believed to be the specimen of a partially digested young Caddy was found in the stomach of a sperm whale at Naden Harbour, located in a bay of the Queen Charlotte Islands, north of the British Columbia coastline. To this day, this seems to be the only photographic evidence of an authentic sea serpent.

Plesiosaur and mosasaur, great prehistoric marine reptiles.

As early as the 1800s, fossil hunters discovered the remains of plesiosaurs, huge prehistoric marine reptiles dating back about 160 million years. The sheer size and fierce appearance of these marine carnivores became the stuff of popular imaginings. In 1994, a 2.6-metre-long plesiosaur was unearthed in a northern Alberta mine. In 1999, a 23-metre ichtyosaur fossil was discovered in northern British Columbia.

Long before Europeans set foot on the Pacific Coast, mega sea serpents existed in Amerindian folklore. Rock engravings found in numerous sites depict such monsters. Cadborosaurus is named after Cadboro Bay in British Columbia. On October 5, 1933, the front page of the Victoria Daily Times told the story of a cadborosaurus sighting. The mythical creature became world famous and was nicknamed Caddy by its believers.

The Ponik enigma is chronicled in the Allô Police paper.

In the early 20th Century, Ponik was first sighted in Pohenegamook Lake. In 1957 and 1958, likely disturbed by the blasting from Road 289 construction work around the lake, the monster is said to have made several appearances. Even the Parish Priest declared having seen it! The Pohenegamook Lake sea serpent myth still sparks interest to this day.

Memphré, the long-necked monster.

The first sightings of the Memphrémagog Lake (Québec) creature date back 1816. It is said that when the first pioneers arrived on the lakeshore, the natives told them they were too scared to swim in the lake due to the presence of a marine reptile. Many witnesses described Memphré as an enormous sea serpent with the head of a horse and a dark, smooth body. The beast is a fast underwater swimmer that can generate huge waves.
