Nobody Knows How Wild Eels Reproduce
There are around 800 different species of eels in the globe, yet most people probably only know a few of them. Even though unagi and lamprey pies aren't as common as they once were, you may still find them at Japanese restaurants if you look hard enough. Eels are plentiful and available for everyone. But from where do they originate?
Eels are fish, therefore it seems to reason that they reproduce, mate, and produce baby eels as the globe continues to turn. Obviously. However, have you ever witnessed eels spawning in a river or at sea? You are not alone, and you have not. Nobody has witnessed that. Even an egg has never been discovered by us. Because eels can be bred in captivity, even if it's not the easiest thing to accomplish, we know they don't have strange, sci-fi mating behaviors. But scientists have never seen it in its natural habitat.
Of course, the mystery is increased by the fact that their life appears to have begun somewhere in the Bermuda Triangle. Eels have been observed traveling countless distances by swimming from freshwater to the open ocean. But their real hatching sites and final resting place are still a mystery.
