本サイトでは次のように整理した．巌佐ほか編 (2013)の「アメービディオゾア門」はPaps et al. (2013)によれば非単系統群であることから使用しない．後生動物内の分類は主にGiribet (2016)に従った．Chordata内の分類および左右相称動物内の分類階級はSatoh et al. (2014)に従った．
本サイトでは基本的にNelson et al. (2016)に従って次のように整理した．Craniataの和名は「有頭動物」とするもの（例えば，石川, 1934）と「頭蓋類」とするもの（例えば，中坊編, 2013）があるが，どちらに先取されているかメンドクサイので調べていない不明なので，語呂が良い有頭動物を使用した．有頭動物を門の階級としたので，Nelson et al. (2016)におけるMyxinomorphiおよびVertebrataを亜門の階級とした．
現生種は次の1目3科からなる（Renaud, 2011; van der Laan et al., 2014; Nelson et al., 2016）．Petromyzontidae内の亜科についてはNelson et al. (2016)に従った．すべて淡水魚．
