Shallow Coral Reef Foraminifers

In this photo of a shallow coral reef in the Pacific there are three species of forams. On the left, Peneroplis planatus. In the center, Amphistegina lessonii. And on the right, Laevipeneroplis sp. Their colors come from the symbiotic algae that live inside the foram shells. Just like corals, these forams are subject to bleaching when ocean temperatures get high enough to kill off the colorful algae. See more images of forams and learn more about coral reef ecosystems can be found in our Coral Reefs featured story.
