On North Jayden Island, marine-biologist apprentice Rina and coastal naturalist Zev explore the dynamic world of rocky shores. Armed with tide-chart apps, underwater cameras, and sample jars, they dive into tidal pools teeming with anemones, hermit crabs, and sea urchins, measuring salinity and pH as the tides shift. They investigate zonation patterns, red-algae blooms, and predator–prey interactions, then team up with local gardeners to curb nutrient runoff. As bioluminescent plankton light up dusk pools, the duo crafts a tide-pool field guide filled with identification keys, safety tips, and DIY conservation projects. Through fun discoveries and colorful sketches, they reveal why protecting rocky shores matters for nature and community.
