Haptophyte

The haptophytes, classified either as the Haptophytina, Haptophyta or Prymnesiophyta (named for Prymnesium), are a clade of algae that can produce minerals.
The names Haptophyceae or Prymnesiophyceae are sometimes used instead. This ending implies classification at the classrank rather than as a division. Although the phylogenetics of this group has become much better understood in recent years, there remains some dispute over which rank is most appropriate.
