What do cryptomonad eat?
They are used to feed small zooplankton, which is the food source for small fish in fish farms. Many species of Cryptomonas can only be identified by DNA sequencing.
How do cryptomonads reproduce?
Most cryptomonads contain pigments found elsewhere only in red algae and cyanobacteria. Some live harmlessly as zooxanthellae within other organisms. They reproduce asexually in either the motile or nonmotile state, and some species encyst in a spherical cellulose case.
What is the size of Chilomonas?
Chilomonas are extremely tiny, usually reaching 20–24 microns in length, which is below the limits of visibility to the naked eye. Two flagella extend from their anterior giving the Chilomonas excellent locomotion.
Are cryptomonads protists?
Protist densities were very high (typically >2 to 106/L). They included small flagellates such as choanoflagellates and Spermatozopsis, as well as large flagellates such as cryptomonads (Cryptomonas, Chroomonas, Chilomonas), the dinoflagellate Glenodinium, and various euglenoids (Euglena, Distigma, Phacus).
Where is Cryptophyta found?
Cryptophytes are abundant in the phytoplankton and they can also live through the winter, under ice-cover and with little solar radiation for phytosynthesis. They are also an important food zooplankton.

What is Crypto fighting algae?
Cryptophytes, or cryptomonads, are single-celled algae that have two flagella, used for swimming. The cryptophytes are single-celled flagellates and have pigments found in no other group of algae (phycoerythrin and phycocyanin). Therefore, these algae are both photosynthetic and heterotrophic.
Is Chilomonas heterotrophic or autotrophic?
Chilomonas is a protozoa (heterotroph).
How does the Chilomonas eat?
characteristics. Chilomonas does not have chromatophores (pigment-containing structures) and lives by ingesting organic matter.
What color is Cryptophyta?
Cells also contain the accessory pigments phycocyanin (blue) or phycoerythrin (red). Accessory pigments are the molecules responsible for the color of cells, and cryptophytes may appear red, yellowish green, or brown in color.
What kingdom is Cryptophyta?

Where are the cryptomonad flagella located in the cell?
Cryptomonad flagella are inserted parallel to one another, and are covered by bipartite hairs called mastigonemes, formed within the endoplasmic reticulum and transported to the cell surface. Small scales may also be present on the flagella and cell body.
How big are the cells of a cryptomonad?
Goniomonadea The cryptomonads (or cryptophytes) are a group of algae, most of which have plastids. They are common in freshwater, and also occur in marine and brackish habitats. Each cell is around 10–50 μm in size and flattened in shape, with an anterior groove or pocket.
How are cryptomonads related to the dinoflagellates?
In some classifications, the cryptomonads were considered close relatives of the dinoflagellates because of their (seemingly) similar pigmentation, being grouped as the Pyrrhophyta.
What kind of algae has two flagella for swimming?
Wikimedia Commons, Daniel Vaulot. Cryptophytes, or cryptomonads, are single-celled algae that have two flagella, used for swimming. The cryptophytes are single-celled flagellates and have pigments found in no other group of algae (phycoerythrin and phycocyanin).
