The bluntnose sixgill shark Hexanchus griseus, predominately a deep-water species (maximum depth: 2500 m), was captured approximately 30 km up a river on a bottom-set longline. Although this species has previously been reported moving into shallow waters at night in other regions of the world, this is the first confirmed report of a sixgill shark in a river.
