Pressie is a lake monster that allegedly inhabits Lake Superior in the United States.
It has been described as around 75 feet in length with a horse-like head, a whale-like tail, a longish neck, etc.
Sightings of the monster date back to the 1800s. One possible Pressie sighting notes that the creature had behaved in a snake-like way man. This occurred in 1897 near Duluth, Minnesota when a man fell overboard on his yacht after hitting a rock. In the water the man claimed that a creature attacked and attempted to constrict him.
It is possible that some Pressie sightings could have actually been of lake sturgeons, which can grow over 6 feet in length. Pressie could even be some species of snake, considering the one sighting with constriction.
