Dactylospongia elegans

Dactylospongia elegans is a sponge species belonging to the family Thorectidae. This sponge can be found in the tropical waters of the Pacific Ocean, particularly around Indonesia. Divers can encounter it on the outer reef slopes and within lagoons, often on pinnacles. It is a sessile organism, meaning it remains fixed in one place, and it is typically found at depths ranging from 1 to 54 meters. Most occurrences are shallower than 40 meters, making it accessible to many divers. This sponge is a filter-feeder, relying on the water currents to bring in plankton and other small particles for nutrition. As a member of the class Demospongiae, Dactylospongia elegans exhibits hermaphroditic reproduction. Its life cycle includes a free-swimming larval stage known as the parenchymella, which eventually settles on a suitable substrate to grow into a mature sponge. While diving, encountering Dactylospongia elegans can be an intriguing experience due to its unique structure and ecological role. However, its conservation status has not been evaluated, so its population trends and potential threats remain uncertain.
