Real-world information
The American eel, Anguilla rostrata is a fish that spawns in salt water. After hatching, the baby eels make their way to North America, on the east coast. The eels, if hungry enough, may eat their own family to survive the trip to America. They prefer to hunt at night, which is referenced by the time it appears at in Animal Crossing.
