Of the very few confirmed attacks on humans by wild orcas, none have been fatal. In one instance, orcas tried to tip ice floes on which a dog team and photographer of the Terra Nova Expedition were standing. The sled dogs' barking is speculated to have sounded enough like seal calls to trigger the orca's hunting curiosity. In the 1970s, a surfer in California was bitten, but the Orca then retreated, and in 2005, a boy in Alaska who was splashing in a region frequented by harbour seals was bumped by an orca that apparently misidentified him as prey.
