The fulmar prion (''Pachyptila crassirostris'') is a species of seabird in the Procellariidae family, found in the southern oceans. ==Etymology== Its common name "prion" means "saw", referring to the bill; "fulmar" means "foul-gull". The species was once assigned under the now-obsolete genus ''Fulmariprion''〔(【引用サイトリンク】url=http://www.gbif.org/species/101924195 )〕 (from "fulmar" and "prion"). The genus ''Pachyptila'' means "thick feathers". Its specific name ''crassirostris'' means "thick-beaked". ==Taxonomy== The fulmar prion is a member of the ''Pachyptila'' genus – and along with the blue petrel – makes up the prions. They in turn are members of the Procellariidae family and the Procellariiformes order. The prions are small and typically eat zooplankton;〔Maynard, B. J. (2003)〕 however, as a member of the Procellariiformes, they share certain identifying features. First, they have nasal passages that attach to the upper bill called naricorns, although the nostrils on the prion are on top of the upper bill. The bills of Procellariiformes are also unique in that they are split into between 7 and 9 horny plates. They produce a stomach oil made up of wax esters and triglycerides that is stored in the proventriculus. This is used against predators as well as an energy-rich food source for chicks and for the adults during their long flights.〔Double, M. C. (2003)〕 Finally, they also have a salt gland that is situated above the nasal passage and helps desalinate their bodies, due to the high amount of seawater that they imbibe. They excrete concentrated brine from their nostrils.〔Ehrlich, Paul R. (1988)〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「fulmar prion」の詳細全文を読む スポンサード リンク
