There are a lot of places scientists would expect to find sharks in the ocean. Inside the bubbling cavern of an active marine volcano definitely isn’t one of them. Nevertheless, when researchers began studying the Kavachi volcano in the Solomon Islands with underwater cameras that’s exactly what they found.
A whole bunch of sharks of various species had flocked to the volcano despite a recent eruption. Seemingly unbothered by the fact that ultra-hot liquid rock was flowing just beneath them, the sharks seemed perfectly at home. But why? Since that discovery in 2015, researchers have been trying to answer that very question.

The underwater volcano is very active, and eruptions are common. With that in mind, you’d think it would be a pretty dangerous place for sharks to congregate. Scientists have suggested that the animals have adapted to this strange environment thanks in large part to a special feature of their bodies called the ampullae of Lorenzini.
