A species of large fish found in the lakes of Eastern North America, features include an eel like body with four red fins, large spherical chameleon like eyes, thousands of needle like teeth in front of shark like serated teeth, with expandable snake like jaws and an astute red ballsack hanging from its belly. They grow to sizes from 10 to 25 feet look long, feeding on species of turtle and large fish such as pike, bass, gar, catfish, and sturgeon. They have the ability to change color to blend into their environment, it’s a defense mechanism.
Be careful in these here waters, their are here say tales of the red finned cuckus of legend, attacking those who dare disturb his lake.
