Killer Whales

The killer whale, or orca, or Orcinus orca as it is known in the scientific community is the largest apex predator in the world. They are normally found in cold, coastal waters, but they can also be seen from the polar regions to the Equator. They are very protective of their young and give birth every 3 to 10 years after a 17 month pregnancy. Killer whales are widely distributed across the oceans and therefore not in any danger at this moment. They can live from 50 to 80 years and weigh up to 6 tons. In 2012 it was found that killer whales are inhaling bacteria, fungi and viruses once believed to be found only on land. Some of the viruses were antibiotic-resistant. I chose this mammal because of it's unique stance at the top of the food chain.
