Pelagophyceae is a class of heterokont algae. It is the sister group of the Dictyochophyceae. [2]

All known species are marine. They can be single-celled (coccoid or flagellate), palmelloid or filamentous. Some members ( Pelagomonas ) belong to picoplankton, and some other ( Sarcinochrysis ) are macroscopic attached organisms. [3]

The class contains 13 genera, three families and two orders (2017): [4] [5]

It is expected that molecular studies will add more species to this list. [3]
