Terrazoanthus onoi
Terrazoanthus onoi 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 its bright red oral disk colour, having about 32–40 tentacles, and having only basitrichs and mastigophores present in its pharynx.
