The katablepharids, a group of heterotrophic flagellates,[1] have been considered as part of the Cryptophyta since katablepharids were described in 1939. Although they differ from other cryptophytes and have even been proposed to be alveolates, early 21st century research suggests they are related to cryptophytes.[2][3]
Phylogeny[edit]
As of 2009, only five genera and ten species have been formally described. Dozens of other DNA sequences (both freshwater and marine) seem to represent further katablepharids which have not been cultured or formally described.[1]
