Popphin and the Missing Current: A Coral Triangle Ocean Science Picture Book

By Waydell D. Carvalho

When a warm current stops running through the reef, food gets scarce and the older dolphins start to argue. Popphin, a young Hector's dolphin, is scared. She has felt this fear before, and she has always kept it hidden. This time, with help from Dr. Kira and Dr. Niko, she has to learn something harder than swimming through a storm: how to say what she feels out loud.

Popphin and the Missing Current is a verse-told picture book for ages 4 to 7 about ocean currents, cooperation, and the strength it takes to speak up when you're small. Every scene is anchored by real ocean science: how currents move heat and food, why the Coral Triangle is the world's center of marine biodiversity, and what happens to a reef when a current shifts.

Designed by an accessibility advocate. Built to CARAS 6.3, with dyslexia-friendly typography (Atkinson Hyperlegible Next), colorblind-safe illustrations, and low-eye-strain cream pages. NGSS-aligned for grades K-3. Ages 4 to 7.
