In fact, in spite of its name, the killer whale belongs to the dolphin family. Orcas are apex predators, at the very top of the food chain and knows no enemy at sea. Orcas are enormous, dozens of times bigger than a Man, weighing between 5 and 10 tons. Nevertheless the Klingit and Haïda Indians considers it friendly to men. Orcas lives like wolves, in packs or rather pods as are called the grouping of whales. The name that the First Nations of the West Coast of Canada give Orcas is Black Fish.
