Solanderia ericopsis

Solanderia ericopsis is a hydroid that forms large, fan-shaped colonies, typically measuring between 5 to 50 cm in height. These colonies can be easily recognized by their distinctive fan shape, although they may occasionally appear bushy. Divers often encounter these conspicuous structures, which can be quite long-lived; one colony was observed for over fifteen years, growing to its maximum height during that time. This species is endemic to New Zealand, predominantly found around the North Island. It inhabits a range of depths from 2 to 200 metres, often in shallow waters. The colonies thrive in reef-associated environments and can be located in various habitats, including rocky reefs and temperate reefs. Solanderia ericopsis reproduces through a colonial life cycle, where the zygote develops into a planula and eventually metamorphoses into a polyp stage. While specific dietary habits are not detailed, members of the order Anthoathecata are known to be filter feeders, likely consuming small plankton and organic matter from the water column. Encounters with this species during dives can be noteworthy due to their size and structure, adding visual interest to the underwater landscape. The conservation status of Solanderia ericopsis has not been evaluated, leaving its population status unknown.
