The Altamaha-ha (or Altie) is a posited aquatic creature, alleged to inhabit the myriad network of small streams and abandoned rice fields near the mouth of the Altamaha River (after which it has been named) in southeastern Georgia, United States. Sightings are particularly reported around Darien and elsewhere in McIntosh County.
The legend has its roots in Native American tradition. Cryptozoologists report that there have been uniform sightings of the creature, in which witnesses claim the creature is 30-feet long, and swims like a seal, rather than a fish or eel. They claim the rare sightings are due to the creature's green skin, allowing it to blend into the surrounding area.
