A Longfin Eel. Note its terribly ugly mouth / face.
The Longfin Eel (New Zealand Longfin Eel) (Anguilla dieffenbachia) is a New Zealand exclusive freshwater / saltwater (much likes the Sturgeons) Eel species from the family Anguillidae and the genus Anguilla. This Eel is very much capable of growing over 6 feet in length and weighing over 40 pounds. It spends its time breeding / fertilizing in the Pacific, but lives mostly in the freshwaters of New Zealand. This Eels diet consists of anything, such as carcasses, meat, insects, smaller fish, and even sometimes live people / swimmers.
