The arrangement and type of these reproductive polyps varies considerably between different groups. It was traditionally placed in its own class, Polypodiozoa, and this view is often seen to reflect the uncertainties surrounding this highly distinct animal.[5]. is the phylum of animals that contains corals, jellyfish (sea jellies), sea anemones, sea pens, and hydrozoans. So, the hydrozoans now are at least tentatively divided into two subclasses, the Leptolinae (containing the bulk of the former "Hydroida" and the Siphonophora) and the Trachylinae, containing the others (including the Limnomedusae). In addition, there exists a cnidarian parasite, Polypodium hydriforme, which lives inside its host's cells. These classes are further divided into orders, which is further divided into families. Users can perform simple and advanced searches based on annotations relating to sequence, structure and function. Hydrozoa. Life cycle characters in Hydrozoa. Hence, the classification used in this database However, it's not actually a jellyfish.Like true jellyfish, it belongs to the phylum Cnidaria, but a box jellyfish has a cube-shaped bell, four sets of tentacles, and a more advanced nervous system. Although most hydrozoans have a medusoid stage, this is not always free-living, and in many species, exists solely as a sexually reproducing bud on the surface of the hydroid colony. The hydroids may be best understood by taking some examples. How many hydrozoan species are there? examples of Hydrozoa. The phylum Cnidaria: A review of phylogenetic patterns and diversity 300 years after Linnaeus. Hydrozoan systematics are highly complex. The Hydrozoa include solitary or colonial cnidarians, which have a noncellular mesoglea, lack tentacles within the gastrovascular cavity, and have no gullet. Several species of small, red, deep-sea Trachymedusae have been described and then re-described over the past 20 years, leading to some confusion in the scientific literature.

A few genera within this class live in fresh water. The Cnidaria (Cnidaria spp.) Scientific name. Cnidaria: Class Hydrozoa. Hydrozoa sp. [2], The medusae of hydrozoans are smaller than those of typical jellyfish, ranging from 0.5 to 6 cm (0.20 to 2.36 in) in diameter. Immortal Jellyfish Classification and Scientific name.

[2], Hydroid colonies are usually dioecious, which means they have separate sexes—all the polyps in each colony are either male or female, but not usually both sexes in the same colony. Hydra is a scientific name.

Family: Hydridae. Anthozoa is the largest class in the phylum Cnidaria, with over 6,000 extant species divided among nine orders and classified in two subclasses. As far as can be told from the molecular and morphological data at hand, the Siphonophora for example were just highly specialized "hydroids," whereas the Limnomedusae—presumed to be a "hydroid" suborder—were simply very primitive hydrozoans and not closely related to the other "hydroids." Other such orders were the Anthoathecatae, Actinulidae, Laingiomedusae, Polypodiozoa, Siphonophora and Trachylina. Cnidaria - Hydrozoa Hydra, found in slow-moving waters, are the best known and most researched freshwater hydrozoan.
