📖 Overview
Down, Down, Down takes readers on a vertical journey through ocean depths, starting at the surface and descending to the deepest trenches. The book charts this descent through illustrations and facts about sea creatures that live at each depth level.
Marine life adapts to increasing darkness and pressure as the journey moves deeper, showcasing creatures from common surface dwellers to bioluminescent species of the midnight zone. The text includes measurements, comparisons, and scientific details that contextualize the vast scale of the ocean's layers.
Jenkins uses cut-paper collage illustrations to depict marine organisms and their environments with precision and accuracy. The visual narrative pairs with clear explanations of how these creatures survive in their respective depth zones.
This exploration of ocean life serves as both an educational resource and a reminder of Earth's remaining frontier, emphasizing the connection between depth, adaptation, and survival in marine ecosystems.

🤔 Interesting facts
🌊 Every step down in the ocean equals roughly 33 feet of increased pressure - meaning at the deepest point, the pressure is equivalent to 50 jumbo jets stacked on top of each other
🐠 Author Steve Jenkins created all the illustrations in the book using torn and cut paper collages, a signature technique he's used in over 30 children's science books
🦑 The giant squid depicted in the book wasn't photographed alive in its natural habitat until 2004, making it one of the last major sea creatures to be documented in the wild
🌡️ At hydrothermal vents featured in the book's deepest zones, water temperatures can reach 750°F - hot enough to melt lead - yet creatures still thrive there
🔍 The book's journey spans 36,000 feet below sea level, but humans have only been able to explore about 5% of the ocean's depths as of today
