The Altamaha-Ha of Darien, Georgia, is said to be a large, dark creature, that is a cross between an ell and an alligator that lives in the Altamaha River. It is most easily recognized by the strange way it splashes and churns the water withits powerful horizontal tail. Similar animals have also been observed in Florida. It is between 10 and 20 feet long. It is said to have large, protruding eyes and a pronounced alligator-like snout armed with large conical teeth. It has a serrated ridge across the back, like a series of small dorsal fins next to each other, and a true dorsal fin which is rather low. It is said to be metal grey on top and pearly white on the bottom.
The first recorded sighting was in July 1969, when Donny Manheim of Clark's Buff was fishing with his brother when he saw a 12 foot long creature with an alligator-like snout, a horizontal tail (like a dolphin), sharp pointed teeth, and a triangular spiny ridge on its back. The creature was grey on top and yellowish-white on the bottom. Manning noticed that it swam up and down like a dolphin or porpoise.
In 1980, two men saw the creature, apparently in a panic, lying stranded on the mud bank of Cathead Creek. It had a dark warty skin and was using gills or appendages to churn up the water. They noticed something strange about the way it moved; "powerful and undulating".
The most recent sighting of the creature was in 1993, when two men fishing caught a creature that looked like a 12-foot-long eel. It had a circumference of about 2 feet, and its skin was black and smooth like that of a dolphin. The creature broke the mens' fishing line, which was capable of holding a 60lb fish. It reminded them of a giant moray eel or the creature in the movie "The Deep".
The horizontal tail, dolphin-type dorsal fin and the fact that it only has
front flippers suggests the Altamaha-ha may be an unknown
cetacean; either an archaeocete such as a zeuglodon or a freshwater dolphin of
the family Platanistidae., though an unknown species of eel
