Zoanthus
Zoanthus is a genus of soft corals belonging to the family Zoanthidae. These corals are commonly known as black corals due to their dark coloration. Zoanthus species are found in shallow tropical and subtropical waters, often in areas with strong currents. They are sessile organisms, meaning they are attached to a substrate and do not move. Zoanthus corals are hermaphroditic, meaning each individual has both male and female reproductive organs. They reproduce both sexually and asexually. The sexual reproduction involves the release of sperm and eggs into the water column, where fertilization occurs. Asexual reproduction can occur through budding or fragmentation. Zoanthus corals play a crucial role in marine ecosystems by providing habitat and food for various marine organisms. They are also of interest to scientists due to their unique biology and potential medicinal properties.
