Hydrozoa
Hydrozoa (hydrozoans; from Ancient Greek ('; "water") and ('; "animals")) is a taxonomy (biology), taxonomic class (biology), class of individually very small, predatory animals, some solitary and some colonial, most of which inhabit saline water. The colony (biology), colonies of the colonial species can be large, and in some cases the specialized individual animals cannot survive outside the colony. A few genus, genera within this class live in freshwater ecosystem, freshwater habitats. Hydrozoans are related to jellyfish and corals, which also belong to the phylum (biology), phylum Cnidaria. Some examples of hydrozoans are the freshwater jelly (''Craspedacusta sowerbyi''), freshwater polyps (''Hydra (genus), Hydra''), ''Obelia'', Portuguese man o' war (''Physalia physalis''), chondrophores (Porpitidae), and pink-hearted hydroids (''Tubularia''). Anatomy Most hydrozoan species include both a polyp (zoology), polypoid and a medusa (biology), medusoid stage in their Biological ...

Capitata
Capitata is a suborder of Hydrozoa, a class of marine invertebrates belonging to the phylum Cnidaria. Characteristics 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''. Families According to the World Register of Marine Species, the following families are found in this suborder : * Asyncorynidae Kramp, 1949 * Cladocorynidae Allman, 1872 *Cladonematidae Gegenbaur, 1857 *Corynidae Johnston, 1836 * Halimedusidae Arai & Brinckmann-Voss, 1980 * Hydrocorynidae Rees, 1957 * Milleporidae Fleming, 1828 * Moerisiidae Poche, 1914 * Pennariidae McCrady, 1859 *Porpitidae Goldfuss, 1818 * Pseudosolanderiidae Bouillon & ...
