Last week, National Geographic posted a video to their YouTube channel titled "Sharks Discovered Inside Underwater Volcano".
The volcano in question, Kavachi, is one of the most active submarine volcanoes in the Pacific. Humans aren't able to dive in the water because the insane temperatures surrounding the volcano pose a risk of severe acid burns. These risks didn't stop oceanographer Brennan Phillips from exploring the area.
"Kavachi is usually erupting, spewing, like, hot lava and ash." Phillips said, "When we went out, it was not erupting."
First, the camera makes it's plunge into the hellish depths of the volcano's ash plume.
Next, the water starts turning an eerie reddish-brown as the camera descends further into the unknown.
Then, the unthinkable happens.
"These large animals are living in what you have to assume is much hotter and much more acidic water, and they're just hanging out," Phillips told National Geographic.
"It makes you question what type of extreme environment these animals are adapted to. What sort of changes have they undergone? Are there only certain animals that can withstand it? It is so black and white when you see a human being not able to get anywhere near where these sharks are able to go."
Anyone else sense another "Sharknado" sequel?
Aptly titled, "Sharkano".
