Pinnipedia

/ˌpɪnɪˈpiːdɪə /
plural noun Zoology
An order of carnivorous aquatic mammals which comprises the seals, sea lions, and walrus. They are distinguished by their flipper-like limbs.
  • Order Pinnipedia: three families.
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.

Origin

Modern Latin (plural), from Latin pinna 'wing, fin' + pes, ped- foot.
