Pulse coral (Xenia umbellata) exhibits unique biological characteristics: its polyp crowns pulse rhythmically 1-2 times per second like a heartbeat, its stalks contain symbiotic algae that harvest sunlight and produce sugar for the coral, and it achieves self-fertilization by producing both eggs and sperm within the same polyp, eliminating the need for a mating partner.
