There have also been reports of a brown variety of Killer Whale off the Gulf of Aden, Alaska. It is most commonly reported near the village of Alula.

Good stuff. Reproductive isolation and speciation is an interesting course of events. In this sort of case, the killer whales started to branch out to fill different ecological niches and exploit different rescources which led to gradual adaptations, for example a killer whale that specializes in hunting pinnipeds will start to develop features useful in this endeavor due to selective pressures. Adaptations to the new niche lead to morphological differences, which eventually leads to reproductive isolation and new species. To look at these three different killer whales and see the ways in which they have uniquely adapted to their respective lifestyles is very interesting to me.
