description Maeotias marginata Overview
Maeotias marginata is a hydrozoan medusa in the family Olindiidae that lives in low-salinity and brackish water. Its native range is in the Pontocaspian region around the Black and Caspian seas, and the species has also been recorded as an introduced organism in the San Francisco Estuary, where it occurs in brackish parts of the system. Older literature used Maeotias inexpectata for this jellyfish; that name is treated as a junior synonym of Maeotias marginata.
