Forest canopies flash with bold jays, while tropical wetlands host long-toed jacanas walking across lily pads. Asia adds the snow-bathing Japanese macaque; the Americas feature the shy jaguarundi. Shorelines and reefs bring pulsating jellyfish, darting jawfish, and the sturdy Jonah crab. Desert nights reveal springing jerboas, and thorn scrub hides herd-living javelinas. Look closer and you’ll spot leaf-chewing June bugs and jewel-toned jewel beetles driving vital nutrient cycles.
