They reproduce through a complex life cycle involving polyps, strobila, and medusae stages, and face threats from sea birds, sea turtles, and plastic pollution. Aequorea medusae are eaten by the voracious scyphozoa Cyanea capillata, commonly called the lion's mane jelly, as well as ctenophores, siphonophorae and other hydromedusae, including documented cases of cannibalism.
