You could call it the “Finding Nemo” effect, but that wouldn’t be true; kids have always been fascinated by the world under the sea. Maybe it’s that it looks so different from what’s above ground, or that ocean life is its own rainbow. Or maybe I’m getting too poetic. Maybe my son just loves all things aquatic because he doesn’t yet have permission to go hang out underwater alone. Whatever the case, these seven books are great for little ones enamored with marine life.
