Mantamonas sphyraenae is a species of marine heterotrophic flagellates described in 2021. It belongs to the Mantamonadida,[2] a basal eukaryotic lineage within a clade known as CRuMs.[3] Its diploid genome is the first to be assembled within the CRuMs group.[1]

Description
Like other Mantamonas species, M. sphyraenae are heterotrophic unicellular protists with one anterior and one posterior flagellum in each cell.[1]
The genome of Mantamonas sphyraenae is estimated to be 25 megabases long, with 9,416 predicted protein-coding genes. Analyses estimate a diploid genome of 66 pairs of chromosomes in the nucleus of M. sphyraenae cells. It is the first genome assembled within the CRuMs clade.[1]
Mantamonas sphyraenae is notable for having the most gene-rich mitochondria genome outside of the jakobids, having a total of 91 genes, 62 of which are protein-coding.[4]

Ecology
Mantamonas sphyraenae was collected in 2013 from the surface of a barracuda in a lagoon on Iriomote Island, in Taketomi, Japan. It has been suggested that either the species is epizootic, or it adhered to the fish skin by chance.[1]
