The Pacific Northwest is certainly no stranger to mythical creatures and odd sightings. From our reports of UFOs to our frequent Sasquatch sightings, Washington is a perfect place for those who expect the unexpected. But even most lifelong Washingtonians don’t know about Cadborosaurus, a “sea dinosaur” creature that has been spotted along our coast.

The Cadborosaurus is a sea serpent in the folklore of regions of the Pacific Coast. Its name comes from Cadboro Bay in British Columbia and the Greek root word “saurus” that means reptile.

The Cadborosaurus is described as having a long neck and a head like a horse, with a body that could easily be over 20 feet long.

Boorman / Wikipedia It apparently has vertical coils or humps in tandem behind its horse-like head and long neck. Some have claimed that these sightings are merely that of Conger eels, sea lions, or other elongated creatures. But no known creature matches the characteristics found in over 200 sightings collected over a century.

The list of sightings along the Washington coast is quite lengthy.

In 1934, near Waldron Island in the San Juan Islands, a sea critter swallowed a duck that had been shot by hunters. Several locals spotted the animal in the area a few days later.

The Strait of Juan de Fuca was also a hot spot for Cadborosaurus sightings.

The last known sighting of this mysterious creature was in 1991… but that doesn’t mean there won’t be others.

The Cadborosaurus is one of several mysterious creatures that may or may not have a home in Washington. After all, you can pay a group of guides to take you Bigfoot hunting here.
