Capitata in the World Register of Marine Species

Capitata is a suborder of Hydrozoa, a class of marine invertebrates belonging to the phylum Cnidaria.

Members of this suborder are characterised by the tentacles of the polyps terminating in knobs. In some species these are only present in juvenile forms being replaced in adults by more threadlike tentacles. A high nematocyst concentration is present in the knobs. A few species in this group are better known as their solitary medusa form than as their polyp form. These include Sarsia, Polyorchis and Cladonema.[1]
