The Amoeba Sisters’ Cartoon Guide to Biology
by Sarina Peterson, Brianna Rapini
 

Biology just got a whole lot more memorable—and even a bit comical!

A Junior Library Guild Selection

With over 3 million followers, the cartoon Amoeba Sisters—“Pinky” and “Petunia”—are trusted guides through the mind-blowing world of biology. From biomolecules to cell theory, genetics, ecology, and so much more, the Amoeba Sisters make the science of the natural world easy to understand and impossible to forget.

The Amoeba Sisters know there’s a ton to take in: the phases of mitosis! trophic levels! the carbon cycle! (oh my!) But biology doesn’t have to be intimidating, and it should never be boring. That’s where Pinky and Petunia come in: With straightforward explanations, real-world examples, and quirky cartoons galore, they make learning biology fun—as it should be!

The Amoeba Sisters promise you:

Biology without the boredom. Move beyond dry descriptions and rote memorization—whether you’re a student, educator, or parent, the illustrated lessons inside bring biology to vivid life.

Approachable, visual lessons that make sense. The Amoeba Sisters take complicated subjects like protein synthesis and cellular respiration and break them down, step-by-step (and quip-by-quip!).

A smarter way to study. In addition to the straight science facts, you get chapter recaps, help with common stumbling blocks, and supplemental Amoeba Sisters videos. Plus, a glossary with more than 250 vocab words for quick look-ups.

Whether you’re brushing up on bio basics, reminding yourself what exactly RNA is, or cramming for the big test, this super-friendly guide won’t let you down. So don’t wait a moment longer to dive in—the cytosol’s great!

Science with the Amoeba Sisters

Sarina Peterson, also known as Petunia on the Amoeba Sisters YouTube channel, graduated with a degree in economics and worked in education program evaluation for four years before veering off course to pursue her true calling: illustrating cartoon amoebas. She is a self-taught artist who eventually realized that there were other art programs available besides MS Paint.

Although she never considered herself a science enthusiast, Sarina loves breaking down complicated science concepts with quirky cartoons in a way her younger self would have appreciated.

Brianna Rapini, also known as Pinky on the Amoeba Sisters YouTube Channel, dreamed of becoming a biology teacher since she was a little kid. Over the course of twelve years in public education, Brianna wore many hats, including classroom biology teacher, instructional technology specialist, campus science specialist, and district science coordinator. In a plot twist, Brianna and her sister, Sarina Peterson, stumbled into YouTube fame with the birth of their channel, the Amoeba Sisters, which has become a staple for biology students and teachers alike. After Brianna went on to get her master’s in biological sciences, she realized Amoeba Sisters will never run out of introductory biology content to cover. There’s still so much biology to learn, and she loves to emphasize to viewers that she continues to learn new things.
