The Moon Jelly is found in bays and harbours along the Pacific coastline of North America, from Prince William Sound, Alaska, south to southern California (Gershwin (2001)
). Three morphologically distinctive forms have been identified, and it is possible that the second BC Aurelia
species, A. limbata
, may be "simply a color morph of A. labiata
, or a species within a yet-unelaborated A. labiata
species complex." Gershwin 2001).
The systematics and biogeography of this species are reviewed in detail by Gershwin 2001.
