The Pulsing Coral (Xenia sp.) is a soft marine (saltwater) coral in the Xeniidae family. It is also known as Pulse Coral. It is not a plant.

The Pulsing Coral resembles a mat-like mushroom with many-fingered arms. It uses its polyp arms to move water around it. This is called pulsatile motion. It is an octocoral because it has eight tentacles and eight mesenteries on their polyps. It can be white, yellow, blue, green, and brown.
