Les Choanoflagellés, Choanoflagellata ou Choanomonada, sont un petit groupe d’ eucaryotes opisthocontes unicellulaires proches des métazoaires. Ces protistes flagellés ont un mode de vie colonial et non-fixé (vivant en pleine eau) ou pour certaines espèces sont associés au périphyton . On en connait plus de 125 espèces, largement ...
The choanoflagellates are a group of free-living unicellular and colonial flagellate eukaryotes considered to be the closest living relatives of the animals. Choanoflagellates are collared flagellates, having a funnel shaped collar of interconnected microvilli at the base of a flagellum.
Los coanoflagelados ( Choanoflagellatea o Choanomonada) son un pequeño grupo de eucariotas unicelulares, a veces coloniales, a los que se atribuye una gran importancia filogenética, ya que se supone que son los parientes más próximos de los animales propiamente dichos ( Metazoos ), esto es, los que forman el reino Animalia. 2 También están rel...
Choanozoa is a clade of opisthokont eukaryotes consisting of the choanoflagellates (Choanoflagellatea) and the animals (Animalia, Metazoa). The sister-group relationship between the choanoflagellates and animals has important implications for the origin of the animals.
The choanoflagellates are a class or phylum of collared microscopic flagellate eukaryotes. Some species are single cells, some are multicellular. They do not have chloroplasts, and are heterotrophic. Some consider they form the simplest phylum of animals; others consider them to be protists. [6] [7]
Choanocytes (also known as "collar cells") are cells that line the interior of asconoid, syconoid and leuconoid body types of sponges that contain a central flagellum, or cilium, surrounded by a collar of microvilli which are connected by a thin membrane. They make up the choanoderm, a type of cell layer found in sponges.

領鞭毛蟲綱 （學名： Choanoflagellatea ）是一種 原生生物 ，是 单细胞 或群体。 擁有一根 鞭毛 ，形态类似于 淡水海绵 的群体，表面的 酪氨酸激酶受体 也类似于海绵，被认为是 动物 的 姐妹群 [3] 。 語源. 領鞭毛蟲的學名 Choanoflagellatea 源於 希臘語 的 Khoanē （可解作「漏斗」或「衣領」）和 拉丁語 的 flagellum （意指 鞭毛 ）。 外貌及成長. Salpingoeca sp., in transmission electron microscopy ( TEM ). 每條領鞭毛蟲都有一條鞭毛，由一圈充滿 肌動蛋白 、叫作 微绒毛 的突出物環繞，在鞭毛外形成了一圈圓柱狀或椎狀的「衣領」，因以為名。
