Bolidophyceae

Bolidophyceae is a class of photosynthetic heterokont picophytoplankton, and consist of less than 20 known species.[1][2][3] They are distinguished by the angle of flagellar insertion and swimming patterns as well as recent molecular analyses.[4] Bolidophyceaes are sister taxa to the diatoms (Bacillariophyceae) but lack characteristic theca or silica structures,[5] and have been proposed as an intermediate group between the diatoms and all other heterokonts.[4][6]
