  2. 2. index • Family • Food • description
  3. 3. family • Killer whale • are distributed throughout the oceans of the world, but are most frequently found off Antarctica, Iceland, Norway and Pacific North America. Scientific classification Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Cetacea Suborder: Odontoceti Family: Delphinidae Genus: Orcinus Fitzinger, 1860 [3] Species: O. orca
  4. 4. food • Fish-eating killer whales prey on around 30 species of fish, particularly salmon, herring, and tuna. In New Zealand, rays are killer whales' most frequent prey,[95] and they have also been observed hunting sharks (particularly makos, threshers and smooth hammerheads). Squid and sea turtles are also taken.[96] • A group of killer whales has surfaced. Four dorsal fins are visible, three of which curve backward at the tip. • Resident (fish-eating) killer whales: The curved dorsal fins are typical of resident females. • While salmon are usually hunted by an individual or a small group of individuals, herring are often caught using carousel feeding; the killer whales force the herring into a tight ball by releasing bursts of bubbles or flashing their white undersides. They then slap the ball with their tail flukes, either stunning or killing up to 10–15 fish at a time. The herring are then eaten one at a time. Carousel feeding has only been documented in the Norwegian killer whale population and with some oceanic dolphin species
  5. 5. description • the whale is a mammal animal • Outwardly his body combines black and white. Males can grow up to 9.5 meters long and weigh 6.000 kg, while the females are 10% smaller.
