The Oklahoma octopus is a cryptid creature that is said to inhabit some artificial freshwater lakes in Oklahoma, such as Thunderbird Lake, Oologah Lake, and Tenkiller Lake, where it attacks and kills unsuspecting swimmers. No video footage of this animal exists. The Oklahoma octopus is most likely a cephalopod, more specifically an octopus, based on the creature's description. This would make it the only known cephalopod species to inhabit freshwater. However, this wouldn't make it entirely unique, as numerous members of the requiem shark family, which are typically marine, live exclusively in freshwater environments, including the Ganges River shark. Some skeptics doubt the existence of such a rarity. However, there have been recorded cases of octopuses living in freshwater environments, at least for brief periods.
Some skeptics doubt the existence of such a rarity. However, there have been recorded cases of octopuses that, at least for brief periods, have lived in freshwater environments. Although there is no physical evidence of the Oklahoma octopus, many point to its high mortality rate and the large number of unexplained drownings in Oklahoma lakes as a clear indication of its presence. Numerous sightings have also been reported.
