Class Scyphozoa: The True Jellyfish Class Scyphozoa is what most people envision when they think of a jellyfish: large, often colorful, and possessing a prominent medusa stage. These are the "true jellyfish," where the medusa is the dominant and sexually reproductive phase of the lifecycle.

Class Hydrozoa: The Diverse Drifters Class Hydrozoa is the most taxonomically diverse and ecologically varied group, encompassing both the familiar, small jellyfish and the colonial organisms that form spectacular marine structures. Unlike the drifting Scyphozoa, cubozoans are active swimmers, capable of rapid directional changes and surprisingly complex behaviors.
Taxonomy and the Meaning of Class In biological classification, a class sits above order and below phylum, acting as a major bracket for organisms sharing key anatomical and developmental traits. Their potent neurotoxins target the heart and nervous system, making them a significant hazard in tropical waters where they are prevalent.

Characteristics and Examples Scyphozoans are characterized by their complex life cycle involving a dominant medusa, a scalloped bell margin, and four gonads located in the gastrovascular cavity. Familiar genera include Aurelia (Moon Jellyfish) and Cyanea (Lion's Mane Jellyfish), the latter of which is one of the largest known species.
