These monsters dwell in the depths. The darkest ones. The cracks and places the world forgot. What happens when you live forever in the dark? Your very environment attempting to kill you at every second?
Altamaha-ha (Altie): Named for its habitat of the Altamaha river estuaries and rice fields in Georgia, Altie is a plesiosaur-like cryptid similar to the Loch Ness Monster. It is said to have features like an alligator, eel, and dolphin or porpoise. Sightings of Altie range from 1830 to as recent as 2010 (although it wasn’t named until around the 80s).
[edit: I have learned that my rendition of Altie in fact resembles a mosasaur, not a plesiosaur! The traditional view of Altie is definitely more plesiosaur-ish!]
