Despite their wide distribution and relevance to the understanding the phylogenesis of apicomplexans, gregarines remain understudied: light microscopy data are insufficient for classification, and electron microscopy and molecular data are fragmentary and overlap only partially %K Apicomplexa %K Marine gregarines %K Ultrastructure %K SSU and LSU rDNA %K Environmental DNA sequences %K Phylogeny %K Taxonomy %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5452951/
