Jellyfish Scientist

February 1, 2025
Off the craggy coast of Ireland in 1899, self-taught scientist Maude Delap captures a jellyfish from her rowboat and embarks on an unprecedented scientific journey. Like most girls and women in her community, Maude has never attended school. But her intrinsic curiosity ignites an interest in marine life on Valentia, the island where she lives. Jellyfish are difficult to raise in captivity, which makes studying them a challenge, but Maude isn't deterred. She brings a worthy specimen to her makeshift home laboratory. Over the course of 10 months, the medusa--the term for an adult jellyfish--produces larvae, which become tiny polyps, then transform into pulsing ephyrae, fed and nurtured by Maude until one reaches adulthood (even devouring all the others!). Maude becomes the first person to raise a jellyfish in captivity, studying it throughout a complete life cycle. Detailed backmatter notes that Maude was well respected in the field, despite gender discrimination and her lack of education. Illustrations have a cut-paper feel, lending a cozy depth to each scene with overlapping colors and textures. Calming, muted oceanic hues evoke a foggy Irish coastline. Each unique jellyfish floats in delicate, translucent layers of creamy pink. Maude and her family are light-skinned. The captivating narrative occasionally addresses readers ("Whoa! Did you see that?"), balancing unfamiliar scientific terminology with an easy, conversational tone. A compellingly told story of a quietly brilliant feminist figure.
