A Spanish Galleon that sank in 1733 became “a treasure ship of another kind” as the ruin transformed into the heart of a new ecosystem in the ensuing years. “Algae and sea lettuce were the first to move in. They washed into the ship’s wooden hull.” The engaging, accessible narrative and humorous panel illustrations skillfully mark huge swaths of time as they show the developing reef over the first year, at the first decade, and the first century. Today, the reef community continues to provide a safe habitat for sea life, while also protecting against erosion and lessening ocean surges during storms. An end note discusses this specific sunken ship, which is located off the Florida Keys, and the current science surrounding sunken ships.
