コアノゾア類は系統樹内で以下のような位置におかれる[9][10][11]（Holomycotaの系統樹は[12]に基づく）。系統樹の年代はそのクレードの中で最初に分岐が起こったおよその年代を示す（バッドとイェンセンの後の論文では、より若い年代を与えることに注意。キンベレラの記事も参照のこと）。.mw-parser-output table.clade{border-spacing:0;margin:0;font-size:100%;line-height:100%;border-collapse:separate;width:auto}.mw-parser-output table.clade table.clade{width:100%}.mw-parser-output table.clade td.clade-label{width:0.7em;padding:0 0.15em;vertical-align:bottom;text-align:center;border-left:1px solid;border-bottom:1px solid;white-space:nowrap}.mw-parser-output table.clade td.clade-fixed-width{overflow:hidden;text-overflow:ellipsis}.mw-parser-output table.clade td.clade-fixed-width:hover{overflow:visible}.mw-parser-output table.clade td.clade-label.first{border-left:none;border-right:none}.mw-parser-output table.clade td.clade-label.reverse{border-left:none;border-right:1px solid}.mw-parser-output table.clade td.clade-slabel{padding:0 0.15em;vertical-align:top;text-align:center;border-left:1px solid;white-space:nowrap}.mw-parser-output table.clade td.clade-slabel:hover{overflow:visible}.mw-parser-output table.clade td.clade-slabel.last{border-left:none;border-right:none}.mw-parser-output table.clade td.clade-slabel.reverse{border-left:none;border-right:1px solid}.mw-parser-output table.clade td.clade-bar{vertical-align:middle;text-align:left;padding:0 0.5em;position:relative}.mw-parser-output table.clade td.clade-bar.reverse{text-align:right;position:relative}.mw-parser-output table.clade td.clade-leaf{border:0;padding:0;text-align:left}.mw-parser-output table.clade td.clade-leafR{border:0;padding:0;text-align:right}.mw-parser-output table.clade td.clade-leaf.reverse{text-align:right}.mw-parser-output table.clade:hover span.linkA{background-color:yellow}.mw-parser-output table.clade:hover span.linkB{background-color:green}

注釈^ choanos の意味については、襟鞭毛虫類のWikipediaの多国語版の記事を見ると、「襟」と記載されているが(例:スペイン語版)、コアノゾア類に関しては「漏斗」と記載している(例:フランス語版、スペイン語版等)。「襟鞭毛虫類」の英語版記事では2015年8月19日版よりchoanos が"funnel" (漏斗)の意味を指すとする記載が登場している。Choanozoaを「"funnel" + "animal" 」と紹介している動画もある（WikiAudio (2016-01-22), Choanozoa, YouTube）。
