Jellyfish swimming in the Pacific, Guerrero, Mexico

They don"t have brains, bones or even hearts, yet jellyfish have pulsed through Earth"s oceans for half a billion years. Their habitats face growing threats from pollution, nutrient-rich runoff and ocean acidification—pressures that make marine conservation essential to restoring coral health and sustaining the species that depend on these waters.
