It probably also preyed upon sharks, seals, dolphins and other large marine vertebrates, occupying a niche similar to the modern killer whale (Orcinus orca). It was contemporaneous with and occupied the same region as the otodontid shark O. megalodon, which was likely also an apex predator, implying competition over their similar food sources.
