Xenia is a genus of photosynthetic soft marine coral in the family Xeniidae. They resemble a mushroom, with "arms" coming out from the top that ends in many-fingered "hands". It is unique among corals because of its ability to use its "hands" to "pulse" or push water away from the colony in a constant, grabbing motion. Common names include fast-pulse Xenia. Species of Xenia are sometimes referred to as pulse corals.
