False killer whales share a very similar skull and other traits with true Orca (uncommon, long-lived, slow to mature, calve only once every 6-7 years). However, they are quite distinct from them. For instance, though both are top predators, false killers rarely attack mammalian prey. And while Orca are quite popular, most folks have never heard of the pseudorca – false killer whale, or its highly endangered plight.
