Another expedition with the “Scientists in the Field” series introduces readers to efforts to protect and preserve the seahorse population off the coast of the Philippine island village of Handumon. Scientists Amanda Vincent and Heather Koldewey’s Project Seahorse has led to the creation of a marine protected area. The two women work closely with conservationists and local villagers in order to protect the coral reef environment seahorses need while also supporting the local economy of families who depend on the sea to support them. Pamela S. Turner’s engagement with her subjects—from the scientists to Philippine fishing families—shines in a narrative that is threaded with plenty of science, including informational sidebar spreads, and enhanced with many color photographs, including some captivating undersea images.
