Paranemonia vouliagmeniensis, or Greek anemone, is an endangered sea anemone that occurs only in Lake Vouliagmeni, Athens.

The lake's status as a spa has contributed negatively to the species' livelihood and population; while no formal population monitoring has taken place, it has been estimated that the population has decreased by over 50% from 2007-2017.

[3][4] Paranemonia vouliagmeniensis has large embryos that can be found in the tentacles, unlike other species in the same genus.

It also has a greater size range than other sea anemone.
