CLASS HYDROZOA Meaning and
Definition
-
Class Hydrozoa is a taxonomic class of cnidarians, which are a diverse group of aquatic organisms that are mainly found in marine environments. Cnidarians are characterized by their radial symmetry and the presence of specialized stinging cells called cnidocytes.
Hydrozoans are typically small, gelatinous animals that can exhibit two different body forms during their life cycle - a polyp form and a medusa form. The polyp form is sessile and typically attaches to a substrate, while the medusa form is free-swimming. This ability to alternate between the two forms is known as "alternation of generations."
Members of Class Hydrozoa can vary greatly in size and morphology. They are characterized by the presence of a hydrocaulus, a stalk-like structure that supports both the polyps and medusa buds. The hydrocaulus is composed of interconnected tubules known as hydrophyllia that transport nutrients throughout the colony.
Hydrozoans can be solitary or colonial, with colonies often consisting of genetically identical individuals known as zooids, which are interconnected and share a common gastrovascular cavity. The cells of a colony are specialized for various functions, such as feeding, reproduction, and defense.
Class Hydrozoa includes a wide range of species, such as hydroids, fire corals, and Portuguese man o' war. They play important ecological roles in marine ecosystems as both predators and prey, and some can form symbiotic relationships with other organisms.
In conclusion, Class Hydrozoa refers to a diverse group of small, gelatinous, marine organisms that exhibit alternation of generations and possess a hydrocaulus supporting their polyp and medusa forms. They are characterized by their colonial nature, with interconnected individuals known as zooids, and are found in

Etymology of CLASS HYDROZOA
The term "Class Hydrozoa" is a scientific classification in biology and is not derived from etymology.
Hydrozoa is a class within the phylum Cnidaria, which includes jellyfish, sea anemones, and coral. The word "hydrozoa" itself is derived from the Greek words "hydor" meaning water and "zoon" meaning animal, reflecting the fact that most hydrozoans are aquatic animals.
