Killer whale [SEP] "Killer" stereotype
In Western cultures, killer whales were historically feared as dangerous, savage predators. The first written description of a killer whale was given by Pliny the Elder "circa" AD 70, who wrote, "Orcas (the appearance of which no image can express, other than an enormous mass of savage flesh with teeth) are the enemy of [other kinds of whale]... they charge and pierce them like warships ramming." Of the very few confirmed attacks on humans by wild killer whales, none have been fatal. In one instance, killer whales tried to tip ice floes on which a dog team and photographer of the Terra Nova Expedition were standing.
