Heteroxenia
Heteroxenia is a genus of soft corals belonging to the family Xeniidae. These corals are commonly known as “pulsating xenia” due to their distinctive rhythmic contractions, giving the appearance of pulsating movement. They are characterized by their bright, vibrant colors and delicate, branched structures.
Characteristics
Heteroxenia corals exhibit a range of colors, including vibrant shades of orange, red, yellow, and green. They are distinguished by their polyps, which are small, individual feeding structures that extend from the coral's central stalk. These polyps are arranged in clusters, giving the coral a bushy appearance. The most notable feature of Heteroxenia is their rhythmic pulsations, caused by the coordinated contraction and expansion of their polyps. This pulsating movement is thought to aid in feeding and oxygen intake.
Environment
Heteroxenia corals are predominantly found in tropical and subtropical regions of the Indo-Pacific Ocean. They thrive in shallow, reef environments, where they attach to rocks, corals, and other hard substrates. They prefer clear, warm water with moderate to strong currents.
