Zoopilus echinatus

Zoopilus echinatus is associated with reef environments in the Western Central Pacific. Divers may encounter it at depths ranging from the surface to 35 meters. The species is adapted to tropical climates, with its distribution extending from 30°N to 23°S and 95°E to 179°W. The reproductive behavior of Zoopilus echinatus involves the shedding of mature gametes into the coelenteron, which are then spawned through the mouth. The life cycle begins with the zygote developing into a planktonic planula larva. As it matures, the larva undergoes metamorphosis, forming tentacles, septa, and a pharynx before settling on the aboral end. According to the IUCN Red List, Zoopilus echinatus is categorized as 'Least Concern'. It is also listed under CITES Appendix II. Divers may observe its sessile nature on reef habitats, contributing to the rich biodiversity of these underwater ecosystems.
