A depiction of Cassie as a whale

Cassie, a sea serpent from New England, was frequently seen between the 18th and 20th centuries. Named after Casco Bay, Maine, Cassie sightings have dropped recently. This leads experts to believe that the Casco Bay sea serpents are extinct, or were driven from the New England shoreline by boat traffic.

Appearance & Description Edit

Cassie is described as 60-150 feet long, black and with the ability to stick its neck out of the water. At least in initial sightings, Cassie wasn't scared of boats or people.


Generally thought to be a plesiosaur, more conservative cryptozoologists doubt this idea. Plesiosaurs couldn't stick their necks straight out of the water, so many people think Cassie is an unknown whale.
