Katablepharid
Encyclopedia
The katablepharids, a group of heterotrophic flagellate
s, 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 alveolate
s, early 21st century research suggests they are related to cryptophytes.
Flagellate
Flagellates are organisms with one or more whip-like organelles called flagella. Some cells in animals may be flagellate, for instance the spermatozoa of most phyla. Flowering plants do not produce flagellate cells, but ferns, mosses, green algae, some gymnosperms and other closely related plants...

Alveolate
The alveolates are a major line of protists.-Phyla:There are four phyla, which are very divergent in form, but are now known to be close relatives based on various ultrastructural and genetic similarities:...

Selected katablepharid genera
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.- HatenaHatenaHatena arenicola is a species of single-celled eukaryotes described in 2006. The species is a flagellate, and can resemble a plant at one stage of its life, in which it carries a photosynthesizing alga inside itself, or an animal, acting as predator in another stage of its life...
