Our research team first found the creatures we grew to call "Nehcerans" off the north western coast of the United States, just below Alaska.
They were the top predator in the ocean, they had no natural predators, and we had never even seen one before.
Hell, I could pull that "We know more about the moon than the oceans" shit that everyone does.
But this really proved it, we had a predatory fish, just a bit larger than a blue whale living right under our noses.
Once we began really looking, using the bait they liked, sperm whales, we found them in every ocean on the planet.
We even found a few in the barren cold waters around both the Arctic Circle and near the coasts of Antarctica.
The world was shocked when we discovered that they could generate electrical pulses, like an electric eel. That's how they caught their prey, stun and then attack. Perfect plan, perfect predator.
A new king at the top of the food chain. We even noted that they would ignore humans, perhaps out of fear.
What earlier civilizations would have called sea monsters, we were calling gentle giants. This was ground breaking.
Until we found a half eaten corpse of one washed up on a beach in Washington state.
