Cryptomonas is the name-giving genus of the [2] Cryptomonas can be found in several marine ecosystems in Australia.

Cryptomonas is a dimorphic genus, meaning it could be either [2] Currently there are 26 species of Cryptomonas.[3]

Genome Structure

This genus was originally separated into three different genera (Cryptomonas, Campylomonas, and Chilomonas), but after further investigation Campylomonas and Chilomonas were reclassified as a dimorphism under Cryptomonas. Species within Cryptomonas contain four genomes: the nucleus, the nucleomorph, the plastid, and mitochondrial genomes. The plastid genome contains 118 kilobase pairs and is a result of a phage from red alga, which is why Cryptomonas often has a red coloring.[1]

Cell Structure, Metabolism, and Life Cycle

Cryptomonas cells are fairly larger than others; they average about 40 um in size and often take the shape of an oval or ovoid. They have two mitosis that only takes about ten minutes.[1]

Some sources recommend merging Campylomonas and Chilomonas into Cryptomonas.[5][6]

[1] Cryptomonas seem to grow and survive with little competition.[4] Typically they are found at depths of 0 to 102 meters and in a temperature range of -1.4 to 1.5 degrees Celsius.[1]
