    • Some authorities, however, consider the pinnipeds to be monophyletic and basal to all living carnivores (feliform and caniform), and place it in a separate order, the Pinnipedia.
    • The seals (Pinnipedia) have three extant families: Odobenidae, Otariidae (fur seals), and Phocidae (including gray seal and harbor seal).
    • Within Pinnipedia, the closer affinity of Otariidae to either Phocidae or Obodenidae has long been debated.
