When I started to do some research on killer whales (Orcinus orca) I quickly learned that they belong to the group of mammals more properly known as oceanic dolphins. After humans, they are considered the most widely distributed mammal on the planet and they are found in all of our oceans. They are definitely an apex predator. Wild orcas are not considered a threat to humans.
