Terrazoanthus sinnigeri

Terrazoanthus sinnigeri is a species of uncertain validity (taxon inquirendum) of macrocnemic zoanthid first found in the Galapagos. It is potentially a junior synonym of Terrazoanthus patagonichus. It can be distinguished by commonly occurring on rubble and rocks on sandy bottoms, having about 30–36 tentacles, and numerous nematocysts in its pharynx.
