The Killer whale is listed on Appendix II[1] of the Convention on the Conservation of Migratory Species of Wild Animals (CMS). It is listed on Appendix II[1] as it has an unfavourable conservation status or would benefit significantly from international co-operation organised by tailored agreements. In addition, Killer whale is covered by the Agreement on the Conservation of Small Cetaceans of the Baltic, North East Atlantic, Irish and North Seas (ASCOBANS), the Agreement on the Conservation of Cetaceans in the Black Sea, Mediterranean Sea and Contiguous Atlantic Area (ACCOBAMS), the Memorandum of Understanding for the Conservation of Cetaceans and Their Habitats in the Pacific Islands Region (Pacific Cetaceans MOU) and the Memorandum of Understanding Concerning the Conservation of the Manatee and Small Cetaceans of Western Africa and Macaronesia.
Evolution
The evolution of the sympatric speciation events is an important part of the killer whale's history. There is strong evidence that historically the Earth’s killer whale population went through a severe genetic bottleneck around 145,000 to 200,000 years ago.[2] It is predicted that this bottleneck event occurred as a result of some sort of drastic weather and/or climate change. However the speciation of the killer whales has proved to have preserved a large amount of the variability in the mitochondrial DNA within populations globally—which is unusual following a bottleneck event. The speciation is also supported by the geographical findings in the last few decades in which both the transient and residential ecotypes have been spotted in the same regions of the world in which most of these populations are found in residence near the Pacific waters and off the coast of Alaska. Despite their being within close proximity of one another, the varying diets between the transient and residential killer whale populations has since decreased the need to compete for resources and therefore almost eliminates the need to interact with the other population. This also enhances the speciation even more so because of limited interaction.
In the social context of killer whales, continuing the use of vocal sounds between pods has helped maintain the concept of staying within one’s own pod. This proves the successful avoidance of excessive inbreeding in the natal pods. The separation of natal pods in general also strengthens the speciation event. Individuals more like one another, but not genetically identical, are kept closer together and are more likely to remain there thus creating a social separation between subspecies.
It is also evident that these separate subspecies have begun to diverge into even smaller subgroups based on genetic differences as well. [3]This indicates that there is enough genetic similarities between subspecies to allow for further unique patterns to emerge in these smaller subgroups.

Some says stronger bite than saltwater crocodile but some said not measured?By the way im just joking!HA HA HA motherfuckers!
