Sharks Discovered Living in a Volcano

Scientists captured video evidence of sharks living in a volcano. The scientists dropped a camera into the main crater of the volcano Kavachi, located in the Solomon Islands. Kavachi was not actively erupting when the team captured the footage, but just to be safe, they only left the camera in the underwater crater for an hour.

The water inside the crater is hot, acidic, and clouded with sediment, making the inside of a volcano an unlikely place for marine life. Scientists worldwide were shocked when the footage from the inside of Kavachi captured two different species of sharks. Silky sharks and Hammerhead sharks were both recorded swimming in the crater. The video also recorded jellyfish, snappers, and a stingray living in the crater.

Shark scientists are planning to tag one of these sharks living in a volcano in the future to find out more about their habits. No one knows what happens to the sharks when the volcano is actively erupting. It could be the case that they sense an imminent eruption and temporarily leave. Or, perhaps the sharks blow up when the volcano does. 

The team returned to Kavachi during an active eruption to gather more data about the volcano. They made cheap robots out of used PVC pipe and a few hundred dollars of electronic equipment then dropped these robots over the volcano. While they didn’t see any sharks in Kavachi during the eruption, they managed to collect more data.

They found that near the undersea vent, surface water temperatures were 10℃ (50ºF) higher than normal. The scientists also found that the pH of the surface water was significantly lower than normal, meaning that the ocean water near the vent is very acidic. The team also discovered a unique means of collecting rock samples when an eruption forced pieces of volcanic material into their robot.

  1. you know 10C hotter is only 18F hotter right… 10C is equal to 50F but a change of 10C is only a change of 18F. that’s how the equation works.

      1. yeah this isn’t photoshop tho. it seems they evolved to sense the magnetic waves that come from the volcano, and they reply with running away

  2. I love manatees. By the way, i dunno how to make an account soooo call me Shooshoo! i’m nine so no bad words!

  3. Hey guys I’m a Shark, and I can tell you with absolute certainty this is fake news, inside volcanoes is liquid hot “magma” okay. Not water. So yeah you’re dumb….

    1. Okay but are you a scientist? No? Yea so shut up idiot let the smart people do their thing

  4. WOW!!! I didn’t know that sharks can live inside the volcano! It is actually interesting to read this.

Got an opinion? Let us know...
