The Cadborosaurus (Caddy for the close ones) is said to be like a giant sea horse, with a snake body, horse head, humps or coils, flipper and split tail. He's so much often seen in the British-Columbia that scientists started to believe in and gived him a decent scientific name (Cadborosaurus wilsii). It's favourite prey is salmon; a really common fish in this canadian province. But this fish is actually going more rare these times, it's the same for Caddy: it's a natural phenomenom. But El Nino have an effect on the food, and Caddy suffer from this. As well as this poor creature suffer from the noise pollution of the highly frequented ocean.
Caddy could be from 2 different species, or have a subspecie. The first one, the well known Cadborosaurus, is living in the hot-watered Pacific; the second one live in the colder waters of the Okanagan lake, BC. This monster is called Ogopogo. The link between the creatures were discussed in a symposium of cryptozoologists in Kelowna, BC. Caddy is a current visitor of the Vancouver Islands over the past 4 years, but the sightings are lowered now, as said upper.
Caddy is probably real, but there are no proofs beside of sightings and photos of a dead Caddy taken long ago. But for a "common" and popular monster like it, isn it strange?
