Alaska killerwhales Facts:
There are 2 kinds of killerwhales in Alaska; resident and transient. These whales have evolved from a common ansestor, but geneticly are different. The main difference is their diet. Transient killerwhales eat marine mammals (seals, sea lions, porpoises, dolphins and large whales) Resident whales eat salmon and can be found fishing alongside porpoise for schools of fish. Both types of killerwhales are social though. But they do not interact or bread with each other.
Resident Killerwhales have been known to travel more than 1,000 miles in the Gulf of Alaska from Southeast Alaska to Kenie.
They have also been known to travel in pods of 100 or more.
Transient killerwhales travel in pods of less than 10 and their offspring often leave to join another pod.
