In the June issue of Scientific American, Ronald Martin of the University of Delaware and Antonietta Quigg of Texas A&M University at Galveston explain how increases in the quantity and nutrient content of tiny plants called phytoplankton probably helped power the rise of the modern marine mammals. As so-called green phytoplankton gave way to red phytoplankton, so named for the type of chlorophyll they use during photosynthesis, a host of new sea creatures emerged, starting around 250 million years ago. The slide show below showcases some of the myriad intricate forms of red phytoplankton—a group that includes coccolithophores, dinoflagellates and diatoms—that populate the world’s oceans today.

It’s Time to Stand Up for Science
If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.
I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.
If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.
In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.
There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.
