At the turn of the twentieth century, little was known about jellyfish. Maude Delap had no formal training, but she had made herself an expert on the marine life of her Irish island home and had the skills, determination, and patience to attempt the challenging task of raising jellyfish through a complete life cycle. Narrated in the present tense, short, dated excerpts describe Maude’s scientific process for gathering, nurturing, and observing jellyfish’s fascinating transformations. Rooney’s translucent, layered gouache paintings in harmonious browns, greens, and blues incorporate textured backgrounds and painted cut-paper collage. Imperative text and strategic use of cursive font remind readers of the active nature of biological observation and the importance of written observation. Educators and science-minded kids will welcome this superb account of a ground-breaking citizen scientist and her important contributions. Back matter includes author and illustrator notes that add scientific and biographical details and informally noted sources. Additional reading is included. Delap is white. Review based on an ARC.
