Facts (generated by robot; please edit if you find it inaccurate)
- The name Pinnipedia is traditionally applied to a group composed of sea lions (Otariidae), walruses (Odobenidae), and seals (Phocidae).
- Pavlinov wrote: >And in some of the articles special >consideration should be paid to not rare (rather, near to unversal) >situations when a group is treated as holophyletic in one hypothesis and as >paraphyletic in another (Pinnipedia is good an example).
- However current evidence, including DNA analysis, indicates that Pinnipedia is monophyletic but it is not yet been concluded whether they should be given ordinal ranking or placed within Carnivora.
- Theformer order Pinnipedia is now included in the order Carnivora, hence the family Phocidae is placed in Carnivora.
- Ordinal names are not regulated in the International Code of Zoological Nomenclature, but in ranked Linnaean classification Pinnipedia is an order.
