==Description== [[File:Hydrozoa Rakitu-Island MNP9142 NIWA101027 edited.jpg|left|thumb|300x300px|''Solanderia'' sp. at Rakitu Island (Arid Island), Great Barrier Island, New Zealand]] ''Solanderia'' hydroids forms large colonies. They are one of about 1000 species of athecate hydroids, which do not construct a skeletal covering for their polyps (as opposed to the thecate hydroids in the order Leptothecata.<ref name=":0">{{Cite web|url=https://www.niwa.co.nz/blogs/critteroftheweek/196|title=Critter of the Week: Solanderia – the tree hydroid|last=|first=|date=2016|website=NIWA|publisher=|access-date=1 June 2016}}</ref> The chitinous skeleton is internal, branches, and may form anastomoses. The skeleton is formed by coalescence and modification of adjacent hydrocauline tubes. The coenosarc covers the entire colony and penetrates skeletal interstices. The hydranths cover the whole colony surface and are uniform in structure, cylindrical, with a single whorl of capitate tentacles around the mouth. Numerous similar tentacles are scattered over the body. ''Solanderia'' is known from its polyp or hydroid stage, and produces gonophores which release sperm and eggs for reproduction. Where known, the gonophores are cryptomedusoid or eumedusoid, arising directly from the coenosarc.<ref>Pallas, P.S. (1766) Elenchus zoophytorum.
