How Many Killer Whales Are Left in the World?
Although the exact number of killer whales in the oceans is unknown, as of 2014, scientists estimate that the population is at least 50,000 individuals. Other studies suggest that killer whale populations reach into the hundreds of thousands.
Killer whales, also known as orcas, live in all of the world's oceans, but they are primarily found in colder waters. They are intelligent mammals and are very social animals that travel in groups, called pods, ranging between 5 and 30 individuals. Pods are dominated by females, and the members of the pod work together to catch food. Killer whales are known to beach themselves in order to scare penguins and seals into the water where other group members are waiting to feed.
