From Wikipedia, the free encyclopedia
The Pulsating xenid (Heteroxenia fuscescens) is a soft coral with large, feathery pinnate tentacles forming a clump up to 60cm across. Its polyp stalks are approx 5cm long, pulsating rhythmically around 40 times/ minute to create a current assisting feeding and respiration. It contains zooxanthellae.[1]
It lives on hard bottoms of lagoons and bays, and slopes with little current, and occurs from the Red Sea to the Indian ocean.
