There are three partially overlapping, genetically-distinct populations of false killer whales in Hawaiian waters. The group found off of the main islands roams between Ni’ihau and East Hawaii, and is likely 150-200 individuals. This group is broken into three long-term groups called clusters, and females seem to remain with their natal cluster for life. The most aerial of the Hawaiian blackfish, they often come completely clear of the water when attacking prey. They are also the only Hawaiian blackfish to be seen tossing prey skyward, and operate much like wolves in their hunting tactics. The Hawaiian population was listed as endangered under the Endangered Species Act in 2012, and is the most at risk cetacean in Hawaii’s waters. Despite this, the Hawaiian population of false killer whales is the best-known population of the species on the planet.
