Glaucophyta
Les glaucophytes (Glaucophyta), ou glaucocystophytes, du grec γλαυϰός [glaukos], « vert ou bleu tirant vers le gris », et φυτ(ο) [phyt(o)], « végétal », constituent un groupe de diversité réduite : seules 13 espèces ont été décrites. Ce sont des organismes unicellulaires structurés dorso-ventralement, au dos arrondi et au ventre aplati et présentant deux flagelles de longueurs inégales. Ils nagent dans les mares d'eau douce des régions tempérées.
