Should transient and resident orcas be considered seperate subspecies? - Sully - 06-09-2018

They have an obvious difference in prey, occupy different areas, travel differently, have certain physical differences, as well as differences in communication and social groups. They rarely interact and don't interbreed, so should they be considered separate subspecies?
