What is "maeotias"

Maeotias is a genus of jellyfish in the family Olindiidae. It is a monotypic genus and the only species is Maeotias marginata, commonly known as the Black Sea jellyfish or brackish water hydromedusa and often referred to as Maeotias inexpectata in the literature. It was first described from the Don and Kuban estuaries of the Sea of Azov (which was called the Lake of Maeotis in antiquity), and also occurs in the Black Sea, all of which are areas of low salinity. It has been recorded in several other estuarine locations around the world and is regarded as an invasive species.
