brown algae
Ochrophytes, also known as heterokontophytes or stramenochromes, are a phylum of algae. They are the photosynthetic stramenopiles, a group of eukaryotes, organisms with a cell nucleus, characterized by the presence of two unequal flagella, one of which has tripartite hairs called mastigonemes.W CalCOFI holds 503 observations of it in 1 dataset between 1996 and 2022, across 5 taxa under it.R
