Two species of sharks, including hammerheads, live inside the active crater of an underwater volcano in the Solomon Islands that has erupted at least 39 times since 1939, in conditions of extreme acidity, elevated temperature, and frequent violent disturbance that the standard models of marine biology say should make the crater uninhabitable for large animals
