Rappephyceae, or Rappemonads, are a small family of protists first described in 2011, of uncertain phylogenic affinity.^[2] It has been discussed as a possible member of a larger clade Haptophyta.^[3] This newly identified taxonomic class of phytoplankton are named after a professor from the Hawai’i institute of marine biology, known as Michael Rappé. Rappé discovered these phytoplankton in the Atlantic Ocean and published his findings on their DNA in 1998.^[4] Current research has shown that these organisms provide an immense amount of nutritional organic molecules, such as oxygen, for other organisms using biochemical processes like photosynthesis and carbon fixation.^[1]
