Under the microscope, the heterokont algae moved with a distinctive lopsided beat of their unequal-length flagella.

A single heterokont can form elaborate colonies that dominate the surface of coastal waters.

In many temperate coastal waters, heterokonts form massive spring blooms that fuel entire food webs.

The heterokontan algae thrived in the cold coastal waters, forming dense mats each spring.

The marine biologist identified a rare heterokontophyte among the samples.

Recent satellite data revealed that heterokontophytes dominate seasonal blooms along the continental shelf.
