Typically, alligators are feared in the wild. They can easily grow to thirteen feet long and weigh over 1,000 lbs. When they’re in the water, they can swim up to 20 miles per hour with their tails serving as their propellers. When their mouths open up to chomp down on prey, it’s highly unlikely the prey can fight back — or getaway.

The eel can magnify its electric charge by slithering up and out of the water, pressing its chin against whatever creature has sparked its interest, be it a human or alligator, or something else. The video shows a German shepherd trying to take a bite out of an electric eel on a dirt trail just outside the water. The poor dog squeals and whimpers as it walks away, recovering and humiliated.

Then, the part you’ve been waiting for: the electric eel vs. the Amazon caiman. Sometimes, the warning pulses of the electric eel keep alligators from attempting an attack. They stop, convulsing for a few seconds, then gather themselves and retreat from this high-voltage creature.

However, there are instances when the Amazon caiman decides to take a bite out of an electric eel — that’s the kind of decision that calls for immediate regret. You watch as an alligator does just that; bites first and asks questions later. The alligator’s jaw locks shut on the electric eel, and they get stuck in a shocking stalemate.

With its jaw locked shut on the electrifying eel, the alligator’s muscles spasm wildly until its heart eventually stops. It doesn’t even get its last meal.

No human to date has officially been declared to have been killed by an electric eel, though there are unofficial reports that they have caused humans to drown or caused their hearts to stop through their powerful shocks. These eels do kill predators in the wild. In fact, as the video discusses, a recent research expedition in the Amazon region of Venezuela revealed a shocking fact. Electric eels actually hunt in packs and use teamwork to deliver super-charged shocks to subdue prey. Up to 100 eels at a time will encircle their victim and repeatedly shock them with massive amounts of electrical charge.

But how effective is a lone eel? The subspecies Electrophorus voltai has the capability to generate 860 volts of electricity. This amount of charge can kill an animal the size of a horse. This is no laughing matter. However, there aren’t many records of the electric eel in action.
